I currently run Michelin tires but have an issue getting a replacement from Discount Tire here in Phoenix. What would be a equal or better replacement tire? I only get approx 48-40K on these 70k tire...
^ Then buy a different brand/tread of tire. And why would you run without a spare intentionally? Used tires are a dime a dozen if you're waiting to make one of your old tires a spare. Craigslist will probably net you a new set of takeoff tires real cheap. Amazon will ship them to your door for less than a tire shop charges, some deals to be had there too.
About 100 different options and sources for tires....today or tomorrow.
