Largest tire on a dually

DMDP · Jan 7, 2015

My '15 350 Dually is scheduled to be delivered next week. Going to try and hold off on tuning it for a little while, but I gotta get some nice rubber under it. What's the largest tire guys are fitting under a STOCK height dually? Camper package and 17 inch wheels. I don't mind buying spacers for the rear tires, just don't want to get into lifting it right now. Any pics would be awesome. Thanks

You could get away with 35s with some minor if any rubbing on the front and might need a 1/2" spacer on the rear between them.

35 12.50 will fit with possible rub in the front but a lower coil spring spacer will solve that ( easy to install and cheap to buy) but you will need a 2" rear spacer with that size . 285/75/17 will fit with no spacer and no rubbing with stock hight

when you say minor rubbing, where? cab pinch weld, fender, or bumper? my 6.4 was leveled with 35 12.50s on stock 18's and it rubed on the radius arms slightly when turning sharp which im not worried about

On the frame at full lock usually

Tires are not going to hit the frame. They might rub the radius arm. You'll need to trim the inner fender, massage the bottom section of the fender a little, and you'll be fine. To clear a 12.50 tire on the rear with factory wheels you'll need a 2" spacer between the duals.

FYI. 295 60 20's clear on Eagle wheels with no spacer.

The SRW trucks come with 275-65-20 from the factory so i would assume that these would fit on our duallys, obviously you would need 20" wheels. That's my plan any way. As far as stock 17's, tires up to 285's will fit but I just dont like how they fit on such a narrow wheel.

Got the truck! Didnt know it was coming with the wide track front end (which is awesome btw). Does that change anything with tire fitment? Ive been taking some measurements but really want to hear someone say "yes I have ran them". Im really against doing any triming of anything to make tires clear. Im leaning towards the Cooper S/T Maxx, 295/70r17 (33.23 x 12.0) and 2 inch spacers in the rear.
