Trying to find out whether I should go with 17s, 18s, or 20s, on my 2007 GMC LMM. I tow sleds a lot in the winter but I will switch out my sets, so these are just for the summer. I think I am going to get a set of Rolling Big Power R94 wheels, (black with chrome insersts of course) my truck is black. Any pictures and recommendations would be great. Also I am just leveling my front end so you can take that into consideration. Thanks alot.

I was in the same spot a couple years ago, the difference in price form 18-20" tires made the call easy. 37X13.5/18 were about $339.00 Each same tire in a 20" the price jumped about 150.00 a tire. I put too many miles on the truck to spend that kind of coin on tires every couple years.

20' gets my vote I like a little more wheel to show

I was in the same boat a few months ago. Actually I put 265's on stock wheels for a few years because I didnt know what size to get. In the end I went with 20's and never looked back. Doing a search and looking at all the different combos also really helped.

I would go with 18's. It's a good balance of tire/wheel in my opinion. Not sure of how big you can go on LMM's leveled. 33's and 18's seem to be a good match.

I went with 17's and 33's due to cost, couldn't justify the huge increase in price for the wheels and tires. Plus, doing as much towing as I do, looks like I'm only going to get 25K-30K miles out of my Toyo MT's, this time next year, I'll be buying tires again. Can't afford $1K tires every two years. Lots of pics in my garage. Chris
