Its getting to the point in my mud truck project where I need to start looking into getting mud tires, I plan on get super swamper TSL's ... The rims i have are 16x12.5, I want to get anywhere from 38" to 42" tires. But im unsure how wide i can go with the tire on a 12.5" wide rim ? I just want to know what is the widest i can go with the tire and still have it fit good on a 12.5 inch rim? THANKS !!!

 

Why would you want wide tires in mud? A 12.5" rim is likely a lot wider than tires offered in the 38-42 range would need. Go to the Interco web site and look at their recommendations.

 

its a daily driver also thats why i want tires that wider for turning
