Our jeeps are like unicorns, I like it!!I know that there are some Toyota 4runners and some other brands that get wheeled, very very rarely do you see them doing the same type of wheeling that you see Jeep wranglers doing. They are usually on trails that any SUV or even a lot of 2wd trucks could do with very little difficulty. It just seams to me, that as I have wheeled all over the US, that for every 4Runner, Tacoma, or other type of off road street legal vehicle, I will see hundreds of wrangler. Then when the trail get difficult, they are almost non existent. I am sure they are out there. Just like there are hot women that are not crazy, it just unusual to actually see them out in the wild.
Depends how big tires you go. Every component is the same other than axles and transfer case. So yeah huge tires can ruin axles. But the sport axles can handle up to 35s.I'm guessing you have a non Rubicon model? Nothing wrong with that if you make the right upgrades. But if you just throw on bigger tires stock and go wheeling you're gonna break stuff.
