What is the biggest tires that i can put on the stock wheels of a 2008 dodge dually and not have them touch when i have my fifth wheel trailer hooked up. thanks.

 

well i guess nobody wants to answer the question

 

IIRC, 265-70/17 is what Dodge spec'd for a factory option.

I currently have that size, from Bridgestone Duravis M700. I like them a lot. I picked up about 1.5mpg with the camper in the bed.

Be careful about that size and different brands, when loaded. Other brands may squat more. The Bridgestone's don't squat much, even with 55-60psi in them.

Im running a 295/75 R22.5 which equates in my brand to a 39.87" tire , with a 6 inch BDS long arm lift kit. I pull trailers all the time with this setup with now problems. All of the trailers are atleast 28 foot long with tandem duals usualy.

 

It depends if you want to use spacers between the duals.I think 285 are real close with no spacer and no load,but dot quote me on that.Do a search on here,thats been asked before.

 

I'm running 35x12.5/R17's on mine, with a 2" spacer.
