Any opinions out there regarding upgrading the tire size for a dually? A tire shop I use often suggested that I stay with the stock size due to the 17" rim's limiting my options on the selection of simular load range tires. Also it was pointed out that the gap between the duals would narrow if not touch when going to a larger and fatter tire. I can understand that to a degree when I'm humping down the highway with my 5'ver which is 16,000 lbs. plus. But on the other hand, I seem to think that the tires look a bit small sitting in the wheel wells on the truck. So.........any past experiences out there from the dually gang? __________________________________________________ ______________________________

 

I too am looking for ideas regarding new tires. Mine are only 235/80/17, and look real small. I am probably going to move up to a 265/70/17. My friend just put 285/70/17 on her 2500, and they appear too wide to use on the rear without spacers, which I don't want to do. To keep the load range and the spacing it appears there is not many options.

 

I have a chevy dually and got bigger (taller and wide) tires than were suggested for the stock wheels, everyone said that the tires would rub. I put them on anyway, I still have over an inch between the tires even when loaded.

If your trucks are cruisers and you tow a lot... maybe you would want to check into bigger wheels, like 19.5" wheels and commercial duty tires. I read on another forum some guys were suggesting bigger tires in back than front... don't do that. (It is not recommend) it upsets your anti-lock brake system.

 

I am currently running 265/70R17 om my megacab dually but i had to add a 1/4" spacer!

 

Its not a great picture, but you can see the added width!

Thanks for the pic, do you also have a side profile photo? The tires look semi aggresive, suppose for the mud / snow where you live. I'm just interested in road tires.

 

They are Cooper Dicoverer SST M/T

As i work in the oil and gas industry, this truck sees the hiway 2x per year! The rest of the time she is mud, snow, and dirt road.

 

i know a guy that had 37s on his stock wheels i think he used spacers between the wheels to make up clearence of the wider wheels

he now has 22s i will dig out the pics for you guys

 

If I had a dually I would get a set of 22.5 Alcoas and tractor-trailer tires. Expensive, but you'll get several hundred thousand miles out of them. Plus they look bada$$.

 

I steped up from 235/85s to 255/85s but I'm also running 16" wheels. That narrowed the gap in the duals to about a 1/2" on the bottom. I hauled 3k of granite in the back and the gap stayed the same as unloaded.
