R-compound tires are a uniquely American factor. Born out of newbie motorsports guidelines restrictions, they’ve advanced into shut cousins of purebred racing slicks–however with simply sufficient puncture and warmth resistance to satisfy U.S. Nationwide Freeway Visitors Security Administration regs for road legality.
Not that they’re really appropriate for that function. Because it says proper on the label, “Not For Freeway Use.” …
Hoosier TrackAttack Race R8
- Greatest lap: 1:24.04
- Common of greatest 3 laps: 1:24.09
The consistency of the R8 is outstanding. As soon as it is available in, it delivers the identical grip and really feel lap after lap. This makes it straightforward to dial in your braking and turn-in factors. It’s not probably the most responsive of the bunch, relying as a substitute on grip to execute fast laps. It’s additionally straightforward to drive on the restrict, although on this tire our Miata was exhibiting a contact of understeer.
Yokohama Advan A055
- Greatest lap: 1:23.39
- Common of greatest 3 laps: 1:23.55
We love this tire. It’s comparable in grip to the Hoosier however a way more responsive dance associate. It combats localized per-corner warmth soak with crisp turn-in traits. This enables for higher mixed loading asks on nook entry after heavy path braking–carving as a substitute of tossing. Better of all, it wanted solely a tough out lap to come back as much as temp.
Yokohama Advan A055 vs. Hoosier TrackAttack Race R8
Whereas the Yokohama Advan A055 picks up time below path braking, the Hoosier TrackAttack Race R8’s shorter gearing claws some again below acceleration.
Pirelli P Zero Trofeo Observe
- Greatest lap: 1:24.85
- Common of greatest 3 laps: 1:25.00
The Pirelli was much like the Yokohama in responsiveness, albeit with much less mid-corner lateral grip. It took just a few laps to reset our expectations and dial in entry speeds to match, because the breakaway attribute was an atypical high-frequency chatter.
Longitudinal grip, however, matched the A055. As soon as conversant in its traits, the Trofeo was enjoyable to drive and constant throughout a session–good for turning laps at your favourite observe even within the hottest circumstances.

Hoosier TrackAttack Race R8 (retest)
- Greatest lap: 1:23.85
- Avg of greatest 3: 1:23.97
Bolting the R8s again on to test for any observe evolution or driver inconsistency, we once more strung collectively a sequence of comparable lap occasions–aside from the primary. Given the residual core temp, the tire required no warmup laps to rise up to hurry this time–or so we thought. Information confirmed it was nonetheless not fairly 100% for the primary half of timed Lap 1.
With a lap time delta of solely a tenth of a second on the primary session, we have been glad with our knowledge.
After we final in contrast the Yokohama Advan A055 to Hoosier’s R7, there was a four-tenths hole favoring the Yokohama. With the R8, the tempo hole hasn’t modified a lot, though the brand new tire is decidedly extra constant and straightforward to drive.
We have been a little bit involved that the Hoosier was at an obstacle this time because of being on its second warmth cycle, however a glance again on the first check warmth cycle throughout the all-Hoosier check reveals the identical tempo hole to the TrackAttack Professional.
As for the Pirelli, it simply wasn’t on the identical stage as the opposite two. It’s a enjoyable tire, however the lateral grip simply wasn’t there to match its rivals. The smaller bodily sizing was probably an element, however the tempo hole was too giant for that to be the only real purpose.
