20x10" wheels? For off roading... I was reading some posts and they were already saying the 18" wheel is too big. Granted I'm only going a few weekends a year, but I've always been about using the car/motorcycle for what's intended for and the H2 is no different.

Does anyone know if a 4.75" backspacing will work with a 13.5" wide tire on an H2 with a Cognito leveling kit?

I run 37x13.5 tires on 18x10 wheels with 4.5" backspacing and get moderate rubbing at full lock, especially when compressing the suspension (torsion bars are cranked so truck sits almost level). I trimmed the lower 4-5" off the inner fender, as it was getting chewed up. On 9" or 9.5" wheels, you're likely to get less rubbing on the fender, but the 4.75" backspacing may result in some minor rubbing on the frame and sway bar. Another concern is if you have rear air ride...more backspace puts the tires closer to the air ride sensors, which could cause damage when offroading.

I would bet the individual that wrote the post has never wheeled with a 20in rim setup. With a 35+ in tire there is still plenty of rubber. Ive wheeled what is arguably the toughest orv in the east on 20's and have yet to see how a 17 or 18in rim could possibly out perform my setup. In fact i have been told by on lookers that my 20in rim with 35in tires has out performed a 17in rim with 37in tires

You will want to stick with 20's.

Btw, txsut just pretends to know what hes talking about.

I do not have the rear air ride suspension.

Ok, so the consensus is that I will be fine with a 9" wide wheel with 4.75 backspacing running 13.5" wide tires?

Thanks I just want to be absolutely sure before I buy a setup and finding out later that it doesn't work...

Not that simple. Even with stock tires/wheels, different H2s have different rubbing issue. Too, you're adding the Cognito kit (which in theory should help). Imho, no way to tell until you try with your own H2. Make sure you can return/exchange tire/wheel, or buy 'em used/cheap on eBay.
