Sidewalls are shagged on 3 of the 4 tyres on my new alloys, but the odd thing is the tread is near enough new, but the alloys were heavily kerbed so i guess some woman owned the alloys before i did, ive had a tyre that would go down every few days but was too lazy and busy to get the puncture repaired and just kept blowing it back up, did about 1000 miles on it before i got pissed off with keep blowing it up and i remember it had more rubber on the inside of the tyre than the outer when we changed it
