Most half-ton pickups bought within the U.S. don’t really include truck tires,” says John Wu of Maxxis Tire. Bafflingly, he’s not unsuitable: Most 1500-collection pickups bought on this nation come commonplace with P-metric passenger-series tires.
To get a real LT-grade tire in your new truck, you need to both go deep into the choices sheet, swap out to upgraded rubber, or make the leap to a minimum of a 2500- collection pickup.
“It’s simply the way in which most individuals use vans,” Wu continues. “Most pickups are mainly passenger automobiles or SUVs with beds. Homeowners would possibly throw a pair baggage of mulch or just a few 2x4s in at Lowe’s or Dwelling Depot, however principally they’re not getting used as high-load automobiles.”
And that’s the important thing time period proper there: load. As a result of that’s what separates a real LT truck tire from a passenger tire that simply occurs to suit a truck.
Once we purchased our 2010 Toyota Tundra, it had plenty of snug and nice bells and whistles, however we knew that 90% of its use would contain hauling a loaded trailer to a race monitor or autocross web site. The tires that the earlier proprietor had put in appeared good sufficient, however they had been way more suited to a big luxurious SUV than a truck that will see some hauling use.
And these tires had been completely incapable of coping with any kind of gentle floor. This level was pushed house at, properly, our house, when the truck nearly acquired caught in our yard–on stage floor–simply because the tires may get zero buy on the moist, muddy grass.
Whereas we by no means plan to go off-roading in our two-wheel-drive Tundra, race monitor paddocks don’t all the time provide probably the most well-groomed surfaces for trailer parking. If we couldn’t even comfortably negotiate our personal yard, we needed to search for some extra succesful rubber.
However did we’d like a “truck” tire? And what even is a truck tire? Is it notably completely different from a passenger automobile tire that simply occurs to suit your truck? That’s the place our dialog with John Wu began.
When our Tundra’s passenger automobile tires practically left us caught in our personal yard, we upgraded to actual truck tires from Maxxis. The outcome: higher grip and elevated load capability.
“When our engineers are designing a tire–any tire, actually–they’ve an inventory of priorities of issues they need that tire to do,” he explains. “Journey, dealing with, steering response, load capability, longevity, off-road traction, highway noise: All of those components and extra are concerned in each tire.”
However designing these components into a selected tire is lots like constructing a personality for a online game the place you could have finite assets to assign throughout a number of skills. Including further hit factors could imply it’s good to take away some harm means and vice versa.
Nicely, the identical is true with tires. “Our engineers will simply reprioritize these design parameters for every tire,” he continues, “whether or not it’s a tire designed for monitor days, the place grip and suggestions are extra vital than journey and put on, or a truck tire, the place load capability is normally the prime consideration.”
When it got here to our Tundra, Wu advised a set of Maxxis Razr AT tires in 33X12.50R20LT to switch our P305/50R20 P-passenger rubber. The surface diameter would barely change, however the load capability and design philosophy could be way more industrial-grade.
These Maxxis Razrs are designated with an F load vary. Meaning they’ve the equal energy of a 12-ply tire from again within the day–when the load vary of tires was outlined by their carcass thickness, not their absolute energy.
Our outdated passenger-based tires carried a C load vary– only a six-ply score–and their accelerated put on and poor journey when towing instructed us lots about why automobile tires aren’t truck tires. Our new truck tires are rated for a load of 3000 kilos per tire and might maintain as a lot as 80 psi of air, making them way more appropriate for doing precise truck stuff.
True LT tires have just a few different variations from P tires. “Normally, you’re additionally going to see a extra sq. edge on the tread and deeper tread blocks on an LT tire,” Wu explains. “That is for a pair causes. First, we’re attemptingto design the tire to have an optimum contact patch below increased hundreds, which is when it issues probably the most. And in addition, we are able to construct somewhat extra depth into the tread simply to provide somewhat extra longevity earlier than the tire must be changed.”
We anticipated the transfer from passenger to truck tires to return with sacrifices to journey high quality, highway noise and steering really feel. (Keep in mind the thought of getting a finite pool of means to attract from?)
However what we skilled was exactly the other. All of the “luxurious” qualities of the truck had been immediately improved after we switched to the LT tires. A part of this could possibly be as a result of we had been changing older tires with newer ones– or possibly the Razr ATs simply hit a candy spot in balancing functionality with consolation.
Our 33X12.50R20LT Maxxis Razr ATs can be found from varied retailers for round $325 every. LT tires are continuously priced a bit increased than similar-sized P tires, however the more money means further capability for doing the issues that vans do. And that was Wu’s commonplace after we requested him learn how to determine between true truck tires and tires that merely match a truck.
“How a lot of your truck’s functionality are you utilizing?” was Wu’s rhetorical reply. “If you happen to’re by no means placing any stress on it–simply driving it prefer it’s a automobile with a giant mattress within the again–then passenger tires are most likely a high quality selection.
“However when you’re utilizing greater than half the max mattress capability a pair instances a month, or towing one thing like a automobile even a few times a month, that’s form of after I begin suggesting having a tire that’s rated for the job,” he says. “You want to choose your tire to deal with your most troublesome utilization state of affairs, as a result of that’s once you depend on your tires the most.”

That is a penalty of the 2wd truck: noisy tires. Additionally (usually talking) aggressive tread blocks like that worsen mileage than quieter HT tires.
However completely agree concerning the load score, when you tow, get AT LEAST a ‘D’ rated tire.
In case you are towing on a regular basis inside the manufactures tow score, the tires that come on it from the manufacturing facility will work at that tow score, even P rated tires.
LT tires maintain much less weight on the identical strain as the identical dimension P tire. So to really enhance their load capability you need to run significantly extra strain. That does nothing to deal with suspension and drivetrain limitations.
With an LT you’ll sacrifice journey high quality, value and usually put on, and in lots of instances with out really growing towing capability.
If traction or high quality is an issue most instances you may right that with out really shifting to an LT
The opposite drawback of an LT is often increased rolling resistance – so gasoline mileage will drop.
Your truck is rated to tow with the tires that got here from the manufacturing facility on it, so a brand new set with the identical load vary will permit you to tow.
If you happen to’re proper on the restrict of the truck, it is going to work higher than vans used to at their GCW, because the SAE commonplace now requires you to stand up Davis Dam and all OEMs that I do know of require that the truck additionally descend from Davis Dam at that weight.
“You want to choose your tire to deal with your most troublesome utilization state of affairs, as a result of that’s once you depend on your tires the most.”
That sums it up proper there.
Over the previous few many years I’ve used my vans solely as vans to haul and tow issues, whereas I take advantage of my passenger automobiles to haul individuals extra effectively than a truck may ever do. I discovered this the arduous means a few instances after I was in my 20s pulling U-HAUL trailers throughout a few strikes. On the primary event I acquired caught in about 3 inches of snow on high of a light-weight glaze of ice following an sudden snow squall going up a slight grade on a really rural U.S. Freeway. The second time I had a blowout on the Interstate. Each situations had been late at night time whereas utilizing the tires nonetheless inside, however close to the highest of their load vary on the acceptable inflation pressures. Not cool. These had been the final set of passenger automobile tires I ever placed on my vans. I’ve managed to keep away from any related subject since.
Pay consideration to inflation pressures! These load rankings solely apply at most inflation pressures. Something lower than max strain means a decrease load capability. Any important change in load will doubtless require a corresponding change in air strain from what’s printed on the sticker in your door jamb. The various of tire pressures to accommodate completely different hundreds ought to be widespread follow for anybody towing the identical trailer at completely different weights, and may be carried over to various hundreds in common passenger automobiles, though the variations are normally not as dramatic as with a trailer, or a pickup. There are tables you may Google that present the connection between %max load vs. %max inflation strain.
One other advantage of mild truck tires over passenger car tires is their general toughness. This turns into evident when you make plenty of journeys down dust roads with bigger and sharper mixture, or when you do issues like make plenty of journeys to the dump. You should have lots fewer punctures and tread harm with mild truck tires than passenger car tires because of the thicker tread blocks and thicker carcass.
If, nonetheless, all you do is drive your Pickup/SUV/Crossover on dry paved roads carrying 4 passengers and the occasional mattress frames, bicycles, and massive display screen TVs, all you will ever want is passenger car tires. Simply do not blast into the primary snow storm of the season in October in your shiny 4×4 with these passenger car tires considering you are still going to have the ability to execute that 75+ mph morning commute such as you did in early September. Wait. How did I stand up on this cleaning soap field?
This appears like producers understanding their viewers (mall transport with the occasional journey to Dwelling Depot to purchase the extra-large bleach and a can of Raid) and faking journey high quality. They do not do that with 2500s.
For a dose of actuality, take a look at drive a brand new 2500 of any model with the ridiculous Firestones all of them include inflated to 80 lbs. That is truck journey high quality.
In reply to rustomatic :
Yah for a very long time Dodge was the one one which did it proper. All of the producers specified one air strain on their massive vans. Usually like 65F and 80R. This was nice when towing. Once you weren’t towing it rode and wore like hell.
Dodge had a loaded and unloaded strain and their TPMS even labored at each pressures. The those who adopted it acquired far more life out of their tires and their truck did not journey like crap on a regular basis

Far more to unpack right here. Once you’re towing, you throw the load half out the window. I imply, sure, you need to be sure the tires can take the load, however that has nothing to do with the way it will deal with a trailer.
LT tires are constructed utterly in another way than P tires. P tires are designed to be compliant and comfortable. LT tires are designed to carry extra strain and never puncture each time they roll over a rock. The online result’s that LT tires have stiffer sidewalls which pays HUGE dividends on sway management.
Put it this fashion… I had an F250 that the fool former proprietor skimped out and acquired P tires placed on it. My Branger has correct LTs. I had utterly white knuckles towing my 3500 lb boat behind the F250, however the Branger dealt with it like a boss.
You additionally must remember the fact that stiff sidewalls don’t have anything to do with weight capability. The sidewall’s solely job is to not explode with the strain contained in the tire, however it’s 100% the air strain that suspends weight, not the stiffness of the sidewall. E vary tires have stiffer sidewalls which helps significantly with towing means, nevertheless it has nothing to do with their weight capability. Their weight capability comes from the truth that they will maintain 80 psi with out going increase.
The opposite massive issue that many overlook is tread deformation. With a P-tire, you give it (for example for instance) 32 psi. Interval. That could be a strain that suspends the load of the automobile and makes a flat contact patch. If you happen to inflate it to 36, you will put on the middle of the tread sooner. Deflate to twenty-eight and you will put on the outsides sooner. That is partly as a result of a passenger automobile might need a 500 lb payload capability so the distinction between empty and full is way lower than the standard truck. LT tires are designed to function over a far broader vary as a result of they could have a 3000 lb payload capability. You may run E-range tires at 40 psi or 80 psi and probably not discover a lot distinction in tread put on throughout the patch as a result of LT tires (particularly the heavier you go, like D and E vary) are designed to not deform the tread as a lot as a P tire as pressures change.
The precise weight capability of a tire is among the least considerations.
In reply to Curtis73 (Discussion board Supporter) :
I used to be a tire man in truck nation for a few years and I could not disagree with you extra.
A lot of the cowboy Cadillacs out right here which are by no means hooked to a trailer and are ran on the producer’s really useful spec (which is usually geared in direction of the towing facet) put on out the facilities lengthy earlier than the perimeters, particularly on the rear axle. A truck made and pressures designed to tow 13k kilos will not be blissful using round with solely 6 or 7k kilos on them. Contact patch is dependant on weight (which might range significantly with and with out a load) and strain (which 99 % of the inhabitants simply run what’s on the door, which is what it takes for max towing capability, particularly on newer vans that may usually throw a TPMS mild until you have acquired them cranked to the door spec of most likely 70f and 80r)
An LT tire in the identical dimension and strain as a P tire has a decrease weight capability than stated P tire (till you transcend the P tires max capability strain, and typically about 10 psi later the LT has the next weight capability)
So most individuals that put an LT tire on a half ton after which simply run them on the inventory strain have significantly decreased the automobiles functionality, and don’t know what they’ve achieved. This isn’t right however it’s what the vast majority of the inhabitants round right here do after they make the change. I can inform you that the overwhelming majority of LT tires on a half ton will not be blissful at 40 or decrease and drive like they’re made out of jello
I used to tow extensively with half tons together with a 30 foot camper and full dimension choose ups that hardly match on my flatbed. I’ve ran P and LTs. I’ve seen no distinction in sway management from correctly inflated manufacturing facility spec p tire to an LT tire inflated to supply the identical weight capability as manufacturing facility. If the argument is I ought to have ran them at a fair increased strain to stabilize the carcass then I simply shrink my contact patch, which is the very last thing I need whereas towing a 30 foot camper. The one main distinction I’ve seen in sway management in equally outfitted vans is DRW vs SRW which makes an enormous distinction.
My place is, when towing inside the producer’s capability, which was designed for the inventory (usually P) tires and pressures, you achieve nothing (possibly sidewall puncture safety, however I’ve pulled loads of nails and screws out of the perimeters of LT tires), however sacrifice the whole lot (value, gasoline economic system, put on life, journey consolation, weight)
I don’t consider that working an LT tire on a half ton that got here with P raises the towing capability in any respect, it doesn’t deal with suspension, or drive practice and if it was as straightforward as throwinh some LTs on and spec the next strain each producer would do it as a result of then they might declare the title of most at school blah blah blah.
I am with Curtis. His expertise mirrors mine. I all the time ditch the P rated tires on my Pickups. Towing or hauling, I need the protection margin in dealing with and sway management that 80 psi offers. Drop it down when not hauling to 50-60 and it would not journey any completely different than with the P tires.

Sway management? Actually? Towing is about stability. Sway is brought on by an excessive amount of reward stability on the trailer. Not by the tires. Nicely, it can be brought on by improper trailer wheel alignment. However once more not by tires.
Subsequent time you could have a sway state of affairs weigh the trailer hitch. And string the tires.
OK grossly overloaded possibly a LT tire would possibly offer you a tiny bit extra load capability.
