I'm not looking to cut a 1.5 or lower 60', But I'd like to get a consistent 1.6ish. Car has just 683rwhp 687rwtq. I've picked up a set of used 15x10 race stars with almost no life on the 275/60/15 Nitto 555r's. Looking at the same size Mickey Thompson ET Street Radial or going with 555r again. Don't want to go bias ply because I've heard not to mix with radial front tires. Thoughts?
