I have a gash of about 1 inch long and it only goes down into the rubber. The gash is about 1/4th inch deep. Don't know how it happened but the gash is located on the outer sidewell near the rim part of the wheel.
I went to Firestone and the man behind the counter said I needed to replace the tire because things like that are unrepairable and dangerous to drive around with.
I am sure this guy knows what he's talking about but I had been under the impression that these little 2 dollar patch kits sold at Wal-Mart were made to repair things like this (put on the rubber cement, wipe it all off except a thin film, let it dry, apply patch) because they say "Radial patch kit" or something similiar.
Just wondering what folks think here about whether I should get a new tire.
