Kuhmo XS?
 

I'm going to be buying some new tires soon. Looking for 285/30/18 and 315/30/18 sizes. My car might see 5k miles of street use and hpde track days. On the fence on whether to just get some toyo r888's or a sticky street tire like the xs or falken 615.

I have used the kuhmo mx before and really liked them except the sidewall could have been a little stiffer.

Any reviews of the XS?

Lots of info on the tire rack. Also they did very well in a recent C&D comparo.

For your app they're perfect, I'm not convinced the R888s heat up quickly enough to be a viable street option. I run the XS on my Fikses...... very sticky, pretty light, price is right :D

Just don't drive in torrential downpours ;)

of the top street tires (the ST lineup) XS has the best dry traction, and is worst in cold/wet.
if you need wet traction for whtever reason, go dunlop

falkens cant compete with any of the tires out now. unless you get them on clearance, dont bother
