Just got 2 bridgestone pole possitions for the rear because I had a nail on one of the rears & it's not patchable. The insides of tire was cracked a little because I droved it for a week with nail on it by putting air 2 times daily. I drive only short distances to work so I thought it was ok to do for a week because I was really busy but guess not, the inside of the tire with nail cracked a bit. After I got the polem possitions on for the 2 rears, the ride feels alot better than before. I could really feel the difference & would recommend this tire.
