It feels awkward referring to our 1991 Toyota MR2 Turbo as an “older” automotive. In spite of everything, we nonetheless bear in mind it profitable our Editors’ Selection award as the very best new automotive again when it got here out. That we drove that first mid-engine turbo Toyota greater than 30 years in the past appears pretty absurd, but right here we are.
So when our MR2 wanted some new wheels and tires, we bumped into some points. We couldn’t merely hop onto Tire Rack’s web site and place our order with just a few clicks. The second-generation MR2 is notoriously difficult to suit with trendy wheels and tires. In truth, that’s a typical subject in our world, particularly when the automotive in query is barely uncommon and some years older.
This MR2 was initially geared up with 14-inch wheels–Toyota ultimately moved to 15s just a few years later–however you possibly can already see the issue with looking for new tires. Because of our automotive’s staggered fitment, Tire Rack doesn’t record any stock-sized tires for our automotive.
Nothing.
The non-obligatory 15-inch setup doesn’t assist, both, as Tire Rack reveals only a single possibility for tires. We would have liked to have a look at modernizing our MR2, and we nearly needed to work backward. First, we wanted to establish some acceptable tires, then discover some wheels to suit them.
Step 1: Tire Hunt
We knew we needed an especially sporty tire however not a devoted observe mannequin. Most of in the present day’s 200tw rubber within the extreme-performance summer time class would fill our wants properly.

This MR2 isn’t going to be an on a regular basis commuter or a “preventing for the final hundredth” observe automotive, nevertheless it wanted to have the ability to do mundane day by day obligation when the temper struck, together with an autocross or observe day with no need a tire change. The 200tw scene is actually constructed on that ethos.
For sizes, our most excessive limiting issue was the general diameter within the entrance. The unique 195/60R14 tires measured about 23 inches tall, and as a result of proximity of the spring perch to the hub, we measured our most doable tire diameter at about 24.5 inches. Switching to coil-overs gives extra choices as a result of it frees up some area, however we weren’t fairly able to make that leap.
Our MR2 initially ran a 205/60R14 rear tire, and that dimension is just about NLA. Nonetheless, we had numerous room vertically between the hub and the perch, that means our greatest limiting issue was width.
So we began to have a look at trendy tires that would offer appropriate exterior diameters whereas nonetheless (hopefully) clearing our fenders. We noticed 15- and 16-inch sizes accessible, however wheel availability and the extra desired width within the rear weren’t at all times choices in these diameters. Ultimately, a 17-inch was seen as the very best all-around use of assets.
As quickly as our new König Hexaform wheels arrived, we test-fit them to ensure our measurements checked out. As soon as they bolted up easily, we felt protected having our Falken tires mounted.
The entrance wheels had good clearance from the strut housings, however the distance from the wheel to the spring perch on SW20-chassis Toyota MR2 is restrictive. A brief tire is a should for automobiles with inventory spring perches.
The rears have loads of vertical room, however our 9.5-inch-wide wheels have been fairly cozy with the strut housings. A good sidewall profile makes rear fitment a lot tidier.
At 23.8 inches tall, a 215/40R17 entrance tire appeared like the very best match. For the rear, we needed to fill out the wheel wells and make the most of the accessible area, however we didn’t need to get into modifying the sheet steel for clearance. Preliminary measurements confirmed we had a bit greater than 10 inches of area between the strut and the fender lip, and the 10-inch-wide, 24.8-inch-tall 245/40R17 tire seemed like a great match.
Taking all this knowledge and cross-referencing what we may use with the businesses that had these sizes in a tire we favored led us to the Falken Azenis RT660. Whereas our testing has proven that different 200tw tires might be able to run an absolute quicker lap time, the Azenis continues to be considered among the best tires within the class for all-around efficiency on each avenue and observe.
Step 2: Wheel Buying
Now for wheels. After we purchased the MR2, it wore a set of Derpmaster 3000 alloys, probably purchased through some Balkan eBay pirate clone web site that stole everybody’s bank card quantity after it despatched them crappy wheels. Certain, the wheels have been ugly, however they gave the impression to be of suspect high quality as effectively.
So whereas something can be an improve, we nonetheless needed a high-quality wheel that correctly match and in addition enhanced the MR2’s retro vibe since this automotive is now older than many of the NFL’s beginning lineup. And, as with our tire state of affairs, we thought our wheel alternative can be tightly restricted.
A flow-formed wheel appeared like the right reply right here. Making a flow-formed wheel includes working an aluminum casting by means of a machine that makes use of warmth and strain to create a robust, light-weight barrel. This often creates a wheel that weighs lower than a standard solid wheel but prices lower than a completely cast mannequin.
“The tooling for circulation forming might be fairly costly, and the educational curve for correctly producing wheels might be steep, however the payoff is in elevated versatility of the molds,” explains König’s Scott Weiss. “That offers us flexibility down the highway that we don’t have with different manufacturing strategies and lets us produce wheels to satisfy increasingly particular calls for.” As Scott provides, all wheel manufacturing in the end flows from buyer demand, however the versatility of circulation forming permits König to react to and serve extra area of interest audiences.
König gives a variety of flow-formed wheels, so we dove into its catalog for a mannequin that met our specs relating to diameter, width, offset and that all-important bolt sample. A mode that labored effectively on our rad-era traditional can be a significant bonus.
We took measurements and consulted some testimonials. The gallery part of the Fitment Industries web site might be an distinctive useful resource relating to discovering workable wheel specs for a lot of fashions of automobiles. It comprises posts from precise customers itemizing wheel specs, tire sizes, automotive setup and any modifications required to suit the combo collectively, and it helped us again up our personal measurements.
All this analysis led us to the König Hexaform mannequin: 17×8 inches with 38mm offset up entrance and 17×9.5 inches with 38mm offset out again. As a bonus, the Hexaform seems to be a bit like one thing from the ’90s JDM scene and invokes among the OEM wheels Toyota provided on the MR2 again within the day. A 17-inch mannequin weighs about 17 to 19 kilos, relying on offset, and determine a avenue worth of a couple of grand for a set of 4.
The 245/40R17 Falken Azenis RT660s within the rear have a really slight quantity of stretch, creating a bit additional clearance under the strut housings. As soon as mounted, it seemed like our rear fitments can be positive with none spacers.
The rear tires stuffed out the wheel wells properly with none trace of interference on the within edges. Underneath full compression, although, we nervous there may very well be some fender interference, so we determined to place a little bit of a roll on the rear fenders–simply to be protected.
We didn’t therapeutic massage the rear fenders a lot–simply sufficient to take the sharp horizontal edge out of play.
Our remaining product makes use of trendy wheel and tire expertise to create a satisfying, retro look whereas providing trendy dealing with.
Our measurements, nonetheless, confirmed that we is likely to be a bit near the strut housing on the within of the rear fender, however it will in the end come all the way down to the form of the tire as soon as mounted. If we had a clearance subject, we figured we may clear up it with a spacer (fingers crossed).
When our wheels arrived, we first mounted them on the automotive with out tires to verify match, as König won’t settle for returns as soon as tires have been added. This gave us an opportunity to verify our measurements and examine that our tire would match positive inside a sure margin of error. As we suspected, the within fringe of the rear wheel sat fairly near the strut housing, however tire form would in the end dictate our path.
Time for the second of reality: We mounted up our Falkens. The rears had a really slight little bit of “stretch”–sufficient to create loads of clearance between the spinning meeting and the strut housing, precluding any want for a spacer. The fronts, as we suspected, match positive.
We did put an ever so slight roll on the rear fender lips–principally to take a pointy edge out of the equation, though we don’t suppose that lip will ever be in play at our present journey top until one thing extraordinarily dangerous occurred. Nonetheless, we thought of a small fender therapeutic massage to be a bit insurance coverage coverage towards a catastrophe, irrespective of how unlikely.
Our remaining product suits nice, seems to be acceptable and gives efficiency past what Toyota ever meant for these automobiles. Now we are able to correctly put down the facility, turn-in feels improbable, and there’s traction for days.
Fashionable, high-performance rubber can actually remodel older automobiles, giving them grip you’ve barely ever dreamed of whereas retaining uncanny highway manners.
