Hoosier SM7 205/50/15 Mounted and Balanced!
Hoosier Racing Tire Sports Car D.O.T. Radial SM7 tires are R6 tires made for Spec Miata (same tire, just marked for Spec Miata). Track and Competition DOT tires developed for who compete in road racing where responsiveness and high levels of grip in hot, dry conditions are desirable. Radial SM7 tires are designed to reward drivers with fast, consistent lap times and extended wear due to their traction and handling.

WARNING: D.O.T. labeled Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire, including D.O.T. tires, on public roads. The prohibited use of Hoosier Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and possible injury or death.

And like all Track and Competition DOT tires, Radial R6 radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It s also essential these tires be stored indoors at temperatures maintained above 32 degrees F.

The Radial R6 features an aggressive tread compound molded into a slick tread design featuring two symmetric circumferential tread grooves. Beginning with a tread depth of 4.5/32", they will not require shaving for competition, however they will benefit from heat cycling before competition to enhance wear and provide more consistent performance, as well as scuff-in during their first laps. A more rounded tread profile extends the life of the shoulders and produces more consistent treadwear across the entire contact patch.

The tire s internal structure features a symmetric construction that uses nylon cord radial carcass plies reinforced by two lightweight steel belts and a spirally wrapped circumferential nylon cap ply under the tread. The tires feature a rim recess design on all sizes. Additionally, their symmetric tread design and internal construction allows them to be mounted on either side of the car (and later be remounted inside out to further extend their life).

Brian's Application Notes: If you want to be the FASTEST at that track event, here it is! If you want a fast tire to last a few more weekends, get our TOYO RR or Nitto NT01 instead. Either way, order up four of any of our wheels with four of these tires and we will deliver them mounted and balanced and ready to roll.


You guys are great! The new suspension is in and the ride is much improved. Thanks for the great service.

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
