I'm having some difficulties finding what the largest tire I can fit under an '05 Dodge 3500 4x4 without changing wheels or using spacers. My local tire dealer says its stock or nothing. Somehow this doesn't sound right but the local tire guy is unwilling to try several different sizes. I asked my local Dodge dealer, as usual totally useless. I'd like to put 275's on as a minimum, would like to go as high as 37's but I suspect that I'd need aftermarket wheels and/or spacers. American Force has some great wheel and tire packages but the price is way out of the park I'm playing in. Any help would be much appreciated.

285's might fit... but you've got to be really careful with duals... because when you put larger tires on you have to keep the tires away from each other... larger tires are usually wider too... so they'll touch each other and rub themselves to pieces... you might have better luck with a 255/85 tall and skinny...

I cant give you any advice as to what will work but i can tell you what wont. 37s are basically out of the question, they are too wide. I had 315/75/16s (35-12.50-16)on my 99 dually with aftermarket wheels and spacers and they were ok unloaded but with our 7,000 pound 30 foot livestock trailer and a full load of cows they rubbed bad. I got luck on a few hundred mile trips with my tires rubbing in the middle. I now run 285/75/16s (33-11.50-16) with the spacers and they are about perfect, but even with the skinnier tire i  have to leave the spacers, without them the tires would rub under a load. I didnt want to go down from 35s but the only 11.50 inch wide tirei could find was a super swamper bogger in a 35-10.50-16, a great tire, and maybe along the lines of what you want, but even though i would love to have 6 boggers on my truck they sure wouldnt last long under my 8,000 pound truck. Im not sure if this helps but i hope it does. Good luck and i understand your tire guy problem, but i dont have a fix for that.

Thanks for th eadvice, looks like I'm going to have to use spacers afterall. I will be towing a 35ft 5th wheel camper trailer. I've seen several advertisements in the DP mag, I'll give them a call. Thanks again guys, much appreciated.

Say what??? I have a 2004.5 which is pretty much a 05 when i buy aftermarket parts. I run 285/70/R17's i dropped load range to a D but i dont tow to maximum GVWR by anymeans. I dont have any rubbing and have plenty of clearance between inside of DRW's. not to mention the Goodyear MT/R's are the best tire  i have ever run. truck has seen too many burnouts and its time to replace them. No doubt going with Goodyear MT/R's again. great in snow, dont notice noise on street, great on wet pavement, acceptable in mud and sand.

Dont buy wheel spacers as they really arent neccesary. i have also seen aluminum wheel spacers from one of the companies that all the studs broke and truck was brought back on a tow truck. we had just installed the adapters 2 days before and we used impacts to run lug nuts up and torque lugs to finally specs. That was a one time thing but still scared me when i saw it on one of the customers trucks.

the 255/85 is a 34x9.5... if that's about the size you're looking for... just know for like a 305/70/17 you're looking at 11.5" wide... and for a 315/70/17 you're looking at 12.5"... here's the formula for converting it...
section width(255) x aspect ratio(85)x 2
                 /24.5                        +rim diameter(17)=34.1

Thanks for the formula, I'll call my tire guy and see if they can get the 255/85's.

I have an '03 3500 dually and was looking at putting on 35x10.5x17 finding several options. Superswamper makes an LTB which is your cheapest option at around $140/ tire but im told i will burn through them quick if on the road under an 8000lb truck. Several companies make this size at a higher price including the Swamper SSR, Goodrich Mud Terrain, etc, etc, good tires that will last longer but a lot more money, $325 each. The nice part is though no rubbing and no spacers required, plus you can use factory rims. Ive got a question though i want to use this truck for pulling through the field, heavy logging trailers etc, although ive been running into problems with the wickedly heavy front end, what are some thought on putting another pair of rims up front and increasing the surface area with duallys on both ends? Turns couldnt be as tight but if your burried up to the grill its hard to turn at all.

you do have the option of gettin wider rims for the front and putting 12.5" tires on front... makes it hard to do a rotation... but it is an option... as for putting duals up front... never heard of it done... and it probably wouldn't work... you would rub if you turned much at all... so some 10" rims with a 35x12.5 or 35x13.5 up front will help float that front end...

I ran into the same problem when i recently went to buy some new skins for my ride.. They told me that i couldnt go any bigger because of the duals aswell.. i thought it was all bs but i ended up getting a set of Big O BogFoots X/T. Even thought they arent any bigger they look a hell of alot better and more aggresive.. fairly good tires in snow and mud also..
