I just got a few used tires form this guy and was wondering if this tire is still ok. Got them super cheap and this was the only thing that is wrong with the tires. Its about 1/8 inch deep all around the tire. I know it is form it being flat and the rim riding on it. The guy hit a pot hole on the 10 and lost his front wheel so im thinking its form the one behind it. Im not going to do anything crazy with them just use them till i can afford new tires after my lift gets in. Any help is appreciated. They are 285/70-17s.
