came out in the thunder and lightnight today to a flat tyre. The tyres are firestone firehawks which were looking ok still with 1 to 2 mm to the tread indicators. had planned to change them around christmas. took off the tyre and saw it has totally worn the inside half inch off the thread and it and the tyre wall have parted company. The tyre looks in good condition till you take it off. I know 155's are hard on front tyres. the car drives well but could this wear be due to shocks or wishbones. Is this excessive wear as to the eye from looking straight at the car or from the sides the tyres look good and not in need of a change. big blow pout if it had happened at speed.
