I hate mud. I live in the midwest and everything is mud. Fields everywhere. People who.take their daily driver and throw a lift and mud tires on it and then go spray mud all over it are idiots. I know, ive been one of them. It just ruins a good truck.
Id personally buy a pos truck and put a good, powerful motor in it and then run some huge rubber ala tye sawzall mod and beat the piss outta that junk.
Since this thread is about stretching tires i dont know. I have 12.5s on a 12" wheel. Not exactly the subject of this thread,lol. I like the squared look it affords me. As I dont like the tiny wheel and huge bulging sidewall look. I agree, do what you want. But dont ask about it unless you're ready.for opinions.
