Tires OEM BMW or NANKANG

The CRS tires hold there grip very well thru out the life of the tire. They can come to heat cycled from the shop but these do work better if you heat cycle them per their instructions before your track day.

I've been on CRS V1's all year and commute to the track about 130 miles in one direction. I'm getting 20 lapping sessions out of these tires before they start to degrade.

Nankang's FT7 tires are good, cheap and can take quite the beating off road without shredding to bits. You won't need M/T tires for your usecase.

For better handling and winter traction, I would consider getting wider tires.

So I got these nankang AR-1 and never run them before. They talk about a break in, a certain amount of heating, the off the car for a full day.

Nankang CRS is worth a look. I’m on my second set because I had good results with them. They have been consistent and good feedback.

nankang is not bad just probably a bit of road noise

When I had BBS RCs I switched from 225/40/18 General Exclaim UHPs to 215/40/18 Nankang NS-II. Not the best tire (by a long shot), on the low end of decent I'd say, but they were cheap and available in the size I was looking for.

F'ing terrible compared to a reputable summer tire IMO.

I had nankang before. Stupid loud and didn't last long at all.
