I plan on getting a set of tires to use at the track. Right now I am not sure which tire I should run. I know alot of you guy and gals here are running the nitto tire, but I also know that mickey thompson has been making racing tires for along time. I plan on putting them on at the track so they won't be seeing any highway driving. Right now on ebay I can get a pair of 555r for 298, but I can order a pair of the et street radials from summit for 351. Should I just bite the bullet and get the et street tires or should I save the 53 bucks and get the 555r tires. I have been told the et streets really hook up well but I have no knowledge of the 555r grip. Help please.
