<div dir="ltr">Lee - I'm not sure where or who you run with, but different sanctioning bodies have different rules regarding tires.</div><div dir="ltr"><br></div><div dir="ltr">For example, the Hoosier A7. which is basically an autocross tire as well as the R7 are NOT approved for use with SVRA and all sanctioning bodies that use the SVRA tire reg. Some groups do allow the R7's - so you have to check with the group you run with. One group that I run with, Historic Racing Group, allows the Hoosier R7's. Talking to other drivers, those tires are at least 2 seconds a lap faster than the Hoosier TDR's that I run to be legal with VRG and SVRA. Also note that some racing groups will let you run the faster tires, but you run with more modern cars that will (mostly) be a LOT faster.<br></div><div dir="ltr"><br></div><div dir="ltr">If the rules for your group are relatively lax, the Hoosier R7 is a very fast tire. If you are just learning vintage, I would stay away from the fastest tires until you get more comfortable with both the car and those drivers around you. That said, if your group requires a minimum treadwear rating, you need to focus on that. For example, some groups say 200 min on the TW and that limits your choices. Also note that in addition to treadwear ratings, some groups have limits on the tire profile so you have to pay attention to that.</div><div dir="ltr"><br></div><div dir="ltr">Last - if you are forced to switch to bias-ply tires, you will have to look at your setup specs, specifically the camber settings. Bias tires run with much less camber than the radials require.<br></div><div dir="ltr"><br></div><div dir="ltr">Regards,</div><div dir="ltr">Bob Lang<br></div><div><br></div>

Currently running Hoosier P185/60zr13 A7 on my Racing Spitfire. Getting ready to order new tires for this year. Wondering if anyone has input on a possibly better choice?</div>
