tire size

[CBrabec]

My '14 3500 came with 275/70/18 Firestone tires but this next spring would like to upgrade to some bigger tires. I like the factory rims so I will stick with those, so I'm wondering if it will be possible to install 35" tires on the factory rims? I already have a front leveling kit to help with clearance.

35's will fit just fine, may have slight rub on the sway bar and control arms at full lock.

Any fuel economy advantage to larger diameter tires? Or does the extra weight of the rubber negate fuel mug increases?

I just went to 295/70/18 and lost a few mpg...but was worth it for being offroad so much...they will fit on factory rims but I went with new ones for the look

I had 285/75/17's on mine until a few months ago and now I run 275/65/20's. Both of them have been on factory rims. They fit fine and I don't notice any appreciable fuel mileage difference.
