Funny you say 20's are a crap choice when this vehicle comes with 20's (obviously in certain trims). Stock wheels are alloy, so why can't I put different alloy wheels on? Load rating is pretty decent 2500 lbs per wheel
Yes, I actually have a cut a tire while on the trail. My Duratracs actually had a cut on the inside sidewall while I was on a trail that I had taken highway tires on before.
Just for you J, I'm gonna try to fit some 35's. 11-11.5 in width. FYI, that'd give roughly 7-7.5 inches of sidewall. About the same as a 33 on an 18 inch wheel, just more narrow. Just for you
A. I should clarify why I say "crap choice". Just because a 20 comes on the vehicle, doesn't mean it's the best choice for rock crawling, or anything other than highways for that matter. I'm not talking about load ratings or even the material it's made from, just the dimensions.
B. if you use a super low psi such as 20 like I can on the bfg km2 285/70-18, you will risk pinching the tire between rim lip and rock or root. In order to avoid this, you will be forced to use higher psi, probably around 35 or more. These is a significant advantage to using low psi which allows the tire to deform over the shape of whatever object.
C.you cannot make use of a 35 without a body lift, that is the next line crossed in maximum sizing.
Basically the lines are:
1-stock wheel and 31.2-31.5, no problem. No mods needed, even fits in spare tire location under vehicle. BFG runs small so the 31.2 or so 265/65x18 works great with no mods.
2- 32" requires mods. 275/65-18. BFG fits easier than Goodyear Duratrac or Michelin but the fit with the mods and snug 8 wheel.
3- 33.7" requires more mods such as 2" strut tower spacer and also requires 8" wheel tucked in as far as possible.
Basically if you cannot do a system deflate and drive around a parking lot to full lock both directions, onto a curb and turned, without hearing grinding, then they don't "fit" anymore than a shoe on your foot 2 sizes too big or too small.
Putting that tire you videod onto the rear, not lowering fully, not testing on the front, was like you getting some boots, putting one on your hand and saying "see, it could work" LOL
