I'm looking for some tires in 255/35/18. these will be primarily for daily driving, i was thinking Sumitomo HTR-Z III or yokohama S.Drives. i'll have a spare set of wheels for any trackdays.

any opinions between these tires or other recommendations

 

i really liked the sumitomo htrz. great grip, long lasting, and cheap.

 

The HTRZ III is a step above the S-Drive. In fact we tested them against the Advan Sport and the HTRZ III came out ahead.
If I can help let me know.
