does anyone make an oversized wheel and tire to replace the dual rear wheels?

 

There are three options.
Go with a large single rear wheel.
Run spacers between the wheels that you would use to run dual wheels on a single rear wheel truck.
Stay with the stock size.

Your choice may change your ability to carry weight.

You have to have clearance between the tires when the truck is loaded, or you will blow the tires from heat buildup.

 

are you wanting to go to a wide single rear wheel, or wider dually wheels?
check out wheel shops that build custom steel wheels like stockton wheel.

sorry for the slow response, my computer had a bad spell. i am interested in going with a wide single on the rear. the trailer i haul only weighs 5,500 so this is not an issue for me.

 

off topic. Have you got stuck with your four wheel drive daully? i have the same truck but it's two wheel drive. i get stuck in anything off road. want to make it four wheel drive but it will cost an arm and leg. different trans., transfer case, drive shafts, front end, (tires, axles, leaf sprinps) steering box cloum. everything. BE cheaper to buy a new truck.

 

I have never been stuck with this truck. if not for the four wheel drive, i would have plenty of times.
