I am sure this has been asked a thousand times but.. what are the biggest tires i can run on a 4x4 dually that will be towing frequently? I dont want spacers, so any help will be greatly appreciated.

Your not going to get much bigger than stock, with out spacers for the rear! A few guy's run 35-37's and still tow daily.

I have run my 35" dynapro MT's with no spacers and no lift. They rubbed up front at full lock. I threw in a 3" suspension lift shortly after and later on added spacers, but I still towed 20,000 pounds without the spacers for a few months.

Ok fellas, I appreciate it. I do have a leveling kit on the front end, but that is all the lift I will run. I appreciate the help. Ram rod, is that the size tires you are running? Thanks :beer

I appreciate it widehips, but are the spacers very safe to use for towing? I pull cows and a dozer and a track hoe some too. I dont want to have to worry about the spacers coming apart. Thanks
