My question is if this tire has to be repaired is it OK to tow with a plug in the tire? Or should I replace it? Tires has about 10k miles on them.
If it is Discount, and if not it should be
, ask the techs there. They know tires. I have had several repaired over the years, and if it were not safe to tow on I certainly would not be using that same method on my vehicle that my wife or I are driving. If they repair it it is safe. If they say they won't, usually a sidewall, then it is not.
10K on trailer tires. How may days sitting, in the Arizona sun, baking? Just a question that I ask myself about time to change tires. In Arizona 3-4 years depending upon the quality of the tire I originally put on. Dry rot in Arizona is a tire killer.
