run the bfg k02 37. Ita tad larger then an 35 but not by much. I ran them with no lift on 0 offset wheels had 0 rub. Other then that the only agressive c rated 35 I know of is made by general and I think they make the bfg mud terrain in a c.
Most people don’t realize that most 35s and 37s are load d and e rated tires. Meant for heavy big 250 and 350 trucks. Those are like Rolling Stones on a light weight small truck. You have to run then at low psi or rattle your teeth out. That’s specifically why the bfg ko2 37 on the raptor...
Njnmdoc is right. I have the perch collars and the ride feels exactly the same as before I did them. I am also running bfg c rated 37 and the car is very comfortable.
