I'm looking at getting a Tuff Country 4" lift, and was wondering how well a set of nitto terra grapplers 305/55-20's would fit. Also Moto Metal 951 (20-9) to fit the tires onto. Are there any issues I need to be aware of before purchacing. I'm sticking with a 4" lift so I can still park in my garage. Please help. Thanks

As long as you get the correct off-set on the wheel you should be fine. I'm running the 6" kit on a 18x9" wheel with a -12mm off-set and a 35x12.50x18 tire and the lift is actually set at about 5" and I have minor rubbing if cranked hard and going over a curb for instance.
