I bought new rear Razr Mx tires for my Blaster and after the third ride I found a quarter inch or so slit in the sidewall of one of my tires. I'm going to buy a new tire to replace it anyway, but was just wondering if there was a way to repair the sidewall slit safely? Since I did not get my money's worth on this tire, I wanted to see if I could use it as a backup in case of another flat. Or should I just trash the tire?
