I have owned my 2000 Prelude since it was new and have driven it very
responsibly, mostly highway mileage. The car came with Bridgestone Potenza
RE92 (205/50R16) tires, since I also have an older (second gen.) 1987
prelude, I don't drive the 2000 that often and have only put 53K miles in
it, today I noticed the front passenger side tire has cracks all around the
sidewall, I can only see the cracking on this tire, the others seem ok. I
check tire pressure every 2 to 3 months and don't recall going over anything
or hitting a curb that could cause such damage and there are no signs of any
wear or tear on the wheels and the tires still have excellent tread.



The questions I have:

1) is this normal wear or could it be possible I damaged the tire some how?

2) Has anyone else had any similar experience with these types of tires?



Thanks, CDMA
