That's good to know. The last 2 sets of tires I got were from America's Tire, which is what Discount Tire goes by in California.Discount Tire will fix any flat for free whether you bought from them or not. I really like my local store and they'll rotate my tires I got from them for free, but I can do it at home in just a few minutes so I do it myself.
Last I knew, Walmart would plug tires for $10. I know places won't do a tire repair if the problem is near the sidewall.
