I get lots of compliments on these wheels. Most people do not understand the weight capacity increase from using these wheels. My truck had some 18" aftermarket wheels on it when I bought it- they were rated to carry 3100 lbs which was too low for our 5th wheel. Having these allow 4500lbs per wheel gives us the safety factor we were looking for.My truck is an oddball - it is a 1973 with a late 80's Dana 60 front axle and a 2002 AAM 11.5" from a Duramax in the rear. Both 8-lug. The wheels fit with no issues and the backspacing looks good on the vehicle. I am running 225/70R19.5 tires now, but I would recommend using 245/70s with these wheels. The 225s are a little too narrow.
