i have a 1984 toyota truck thats all stock and i want to put larger tires on it,and black rock crawler rims. i really want to try to put 33s on it. i am about to put 63 inch chevy springs in the rear and maybe rears up front im not sure. my question is will i have top regear with 33x10.50x15 and what width rim to go with either 7 inch or 8 inch and what size backspacing should i go with. if i have to regear what should i regear it to. also any inputs on tires would be great im thinking about bf goodrich at ko's. i use the truck as a daily driver but i want to be able to offroad well to thanks Nick

4.88's are recommended for 33's

Its relevant to you, if YOU need to regear.

I run a 8" wide wheel on a 12.50 tire. No problems there.
