tirerack.com of course.I had a 2003 acura CL type-s. The original tires are michelin and they were quite expensive for the quality and durability.When I changed, I went for Yokohama avid V4SThey were almost half the price. THey lasted longer and they were grippier. They were more rigid than the michelin and it helped in taking curves. They were maybe a little bit noisier but I can't even be really sure.You should look them up if you don't want to spend too much.
