Soon I hope to have my new suspension installed, but I still have no ideal what wheel/tire combo too run.

To catch you up, I presently have a small lift (2"poly spacer) and run 255-85-16 tires, with a rear spacer. The new lift(skyjacker 4. 5" system), with Fab Tech dual shock mount and Fox reservoir shocks all around. In the rear besides the new leaf springs I will run Firestone air bags, and traction bars. To keep things real, I want to keep one set of my 16 inch tire/wheel combos for winter and when I need to tow and sell off the other set. I do not expect a dually to fully function with large tires, and the added height they bring.

For new wheels/and tires I am thinking about switching to 17" wheels and going with a 37x13. 50x17 tire. I thought about the 19. 5" option, but the thought of 16ply tires and there awful ride, and no real off-road tire selection put that thought out of mind.

I would like to have wider rear wheels then the normal 6" ones, but can not find any without going full custom and they are just to expensive. So I figure I will stay with the normal 17x6" rear wheels and find a brand/style that allows me to run a dually rear wheel but also allows me to run the same style wheel up front, but in a wider non-dually width. This leads me to where I am now, looking for a brand that offers dually wheels, and regular wheels of the same style. The reason for a non-dually wheel up front was to get away from the confines of a wheel 6" wide. I would prefer one 8-10" wide, what do you think?????

For a tire I would like to stay in the 37" range, and get them as narrow as possible something like 12. 50-13. 50, and of-coarse with an off-road type tread. I currently have a set of BFG MT's, and a set of Trxus MT's both in the 255-85-16 size. I like both sets of tires, they run smooth and seem to get good mileage. I would like my next set of tires to be close to what I currently have, which leaves the extreme off-road tires out, they have to be practical for everyday use.

What have you guys been running? Any ideals, comments or suggestions?
 
Hey how are you doin I live about five minutes from rickson truck accesories and wheels in hunt valley MD. Ihave had two set from him and I loved them. He takes alot of time in taking all the precautions to prevent the dreaded rough ride his match mounting and balancing is real it is no gimmick he has spent alot of money and time in machines. so depending on what you plann on doing with the truck you should look him up ricksontruck.com with what setup you are saying you have you can go with like a 265 19. 5 tire and it would look sweet and be functional. just go on his website and see for your self from all of the customer pics.
 
I thought about 19. 5" wheels, but like I said I don't want the rough ride of the high biased ply rating, and truly they do not offer the type tire and tread I wish to use.
