I need to mount some heartland tires they have a red spot and a yellow spot how are those supposed to be mounted should one of those be next to the air valve

If you don't know what you are doing...have a professional do it for you so you don't put yourself and others in danger.

Stacy is correct! Too many things could go wrong! My son's first job was there, and 20+ years later, Discount Tire is still the only company our family will used! For a nominal fee -$50, they guarenteed all 4 times lifetime replacement!
