MizuTigr Racing Posted January 27, 2019 Report Share Posted January 27, 2019 Trying to develop a plan to run a 2001 Spec Miata but unsure what tires are recommended/allowed. Currently running Hoosier SM7's but someone told me they aren't allowed. Any suggestions would be appreciated. Quote Link to comment Share on other sites More sharing options...

Currently running Hoosier SM7's but someone told me they aren't allowed. Any suggestions would be appreciated. First off, read the rule book.... That said, 180tw is the tread wear rating limit. Hoosiers are a no go, plus you'd be going through a lot of them in a weekend. Most popular tires seem to be Hankook RS4, Dunlop Dirrezza Star Specs, Bridgestone RE71, as well as others. 1 Quote Link to comment Share on other sites More sharing options...
Team Infiniti Posted January 27, 2019 Report Share Posted January 27, 2019 (edited) Expanding on that, following the above advice in the 200 TW range will get you a whole race without having to worry about tires, Anything else won’t last as long or probably not legal Excluding RE 71 , they are fast and legal but don’t last Edited January 27, 2019 by Team Infiniti Quote Link to comment Share on other sites More sharing options...

True though in a normal weather event anywhere from 3-7hrs has been reported on life. I would also say the Toyo's are similar in being fast but won't last. We get around 30hrs out of a set of RS4's in our Miata. Also, word of advice since they are no longer a sponsor, the Maxxis tires, in our teams opinion, were rubbish and easily 2 seconds off pace of the RS4's as well, so I would stay away from those unless you are out of options.

Administrators E. Tyler Pedersen Posted January 27, 2019 Administrators Report Share Posted January 27, 2019 Welcome! The Rival-S 1.5 is a no go as well. It's a dedicated autox tire and won't last a race. Quote Link to comment Share on other sites More sharing options...

oddcarnut Posted January 30, 2019 Report Share Posted January 30, 2019 Perhaps we are just too slow with the Chandler Miatas but we've had no problems getting a full race weekend out Rival S, 225/45-15. Did the VIR 24 one set per car as well as AMP on a single set. Last time I ran Piggy at Rd All, we did the fully race on a set of 225/45-17 Rival S.

Not at all, we were on latest edition of Rival S. For full disclosure, I work for Michelin/BFGoodrich motorsports... Of course other folks results vary as function of tracks, cars, driving style, etc. etc...Depending upon who we have in the Chandler cars the tires may go longer on one car than the other...We had more than 30 race hours on one set between VIR, AMP and a track day at Roebling. Now had I run those same events with our old SAAB 900, no way the front tires would have gone that distance. The original Piggy was a piggy when it came to eating front tires at many tracks.

Other teams have and they have the life like a RE71R. If you're getting 14 hours out of them that is great. You're lighter as well. Use the tire more to get faster Quote Link to comment Share on other sites More sharing options...

We also have found we get a fair amount more time out of the go fast tires due to overall weight of the car. Quote Link to comment Share on other sites More sharing options...
