Any word on the actual circumference of the 245/35 r15? Such a strange size. I heard they run a bit wide, does that mean that their profile is enlarged also? Should be if following the % rule. I really don't want to lower my car any more than it is, as well as the shorter gearing associated with going to these. For reference, 2004 MSM, currently running 245/40 r15 RS4s on a 9" wheel.

I picked up a set of 17 inch wheels this week. Too few options for 16 inch sizes. Currently using 225/50-16 RE71rs, for autocross. Class limited to a 7 inch width wheel.

I will be trying the P1 in 225/45-17 after I finish off the Falken 660 tires on the 17s.

Not seeing much discussion about these on low power FWD cars.

Excellent artcile and feedback from everyone! Im in hot pursuit for some new racing tires before the season starts up for me. I run intermediate on track with a 2018 M3 (stock) and im coming off of Toy R888s. Yeah i know. They did serve me pretty well but def looking for something more consistent that will give me more confidence in high speed corners and just increasing my times overall while maintaining thru each session all day. These sound like the ticket. I've research the crap outta just about everything else. 

Anyone have exp with these on an M3/M4 or similar?
