I have a 99 Ram 4x4 with factory tow/off road/sport package I also added skyjacker coils to the front for 3 inch of lift and added 2 leaf springs to the rear for around 2 inchs of lift.
What is the biggest tire I can put on there with out going to aftermarketed rim?
Biggest tire diameter with aftermarket rim?
I currently have 265/75R on factory rims
I just rebuilt my differntials have 4.56 yukon gears with powertrax locker in rear so gearing is not an issue. This truck sees alot of off road action but i still need to be able to pull the car trailler and camper with it. so 15 inch wide tires would put way to much stress on the barrings.
Any ideas or experience would be greatly appreciated

 

I'd say 305/70s would be about the largest you could go, and even then you'd still have some slight rubbing on the control arms.

 

I'm not going to recommend sizes anymore. I tried that with radwebster and his rubbed.

All I can say is that a 3" susp. lift with a 10" wide wheel with a 33"X 12.5 tire will work for some (me), with no rubbing.
A 35"X 12.5 tire fit mine with the same susp. lift and a 3" body lift.
The truck was stock with 265/75/16's
