So yes, fitting 35’s are definitely possible and without any additional mods. The 35 is a common upgrade and still retains the trucks practicality and off-road abilities.

The 35 can it snug inside the wheel arch and still allows full articulation and droop, which is fantastic.

Biggest Tire on Stock Suspension

We’ve since established that the biggest tire you can fit on the stock Ram 2500 wheels are a 35 inch tire x 12.5” width, without any additional modifications. This means there is zero rubbing or fender trimming required. This tire size is the easiest and most hassle-free tire option and a straight bolt on fit. This tire size will work on the Power Wagon, 2500 and 3500 Ram trucks. This tire choice offers a nice balance between street, off-road and towing practicality.

What if you want to go more aggressive on the tire and are prepared to do additional modifications to make it fit on a stock suspension?

Maximum Tire size on the stock Ram 2500 suspension with some modifications

So this section is to determine what the absolute maximum tire size you can get away with on the stock wheels and stock suspension.

Take note that in order to make the biggest wheel fit, you’ll have to accept there will be some light rubbing on the radius arm fastener, as well as wheel rub on the sway bar. You should be prepared to do some trimming on the inside of the wheel fender liner. You can go as big as a 37×12.5” tire on the factory stock wheels. This will be the same for 2500, 3500 as well as Power Wagons on stock wheels. The wider offset factory wheel on the power wagon is actually going to make this easier and with possibly less modifications.

Maximum Tire size on the stock Ram 2500 suspension + Aftermarket wheels

Now if you’re prepared to spend a bit more and do the modification a bit better, then you should really opt for an aftermarket wheel with the correct positive offset. This will negate the need to do much trimming and cutting of the wheel fender liner and will look so much better. In this instance you can push the upper limits of 37” tires.

The maximum tire you can fit with an aftermarket wheel would be a 37×14.5” fitted on a wheel with an offset between +18mm and +27mm. Avoid all zero (0) offset rims and anything with a negative offset.

The main thing here is the offset of the aftermarket wheel. Understanding offset is quite simple.

In short, the more (-) negative the wheel offset, the further out the wheel sticks out (Show truck style). The more positive the offset the more flush the outside of the wheel sits relative to the wheel hub. In other words, a negative offset wheel moves the center line towards the inboard side of the rim, thus pushing your tires further out. Offset is the distance from the wheel mating surface to the center of the tire tread.

Will 35” Tires Fit Stock Dodge Ram 3500 Dually (FITMENT GUIDE)

Big tire is one of the most popular upgrades most truck owners do and usually the first. Bigger wider tires enhances the look of the truck, as well as improves the way it hauls heavy loads. Bigger tires ads stability and improves the trucks towing abilities. In order to fit 35” tires to a Ram Dually, you’ll need a minimum 2” front leveling kit combined with well-engineered hub centric ¼”steel spacers between the duals, running 35×12.5 tires.

This configuration offers enough clearance to prevent tire rub at full lock and scrubbing at full articulation. It’s a very practical upgrade in that you improve looks but also the trucks practicality isn’t lost.  High grade quality steel spacers are a must so don’t cheap-out on low cost aluminum versions. Ensure you fit a 1/4″ spacer on the rear to prevent the tire chaffing on the rear leaf packs.

Running 35 inch tires on a Ram Dually (Spacers vs Aftermarket rims)

When doing a big tire upgrade, there’s always the cheaper way versus the proper, yet more expensive approach. There are, however, many Dually owners who’ve fitted spacers instead of aftermarket wheels and swear they’ve never had any hassles at all. However, if you really want to run 35’s on the dually, if possible, invest in a set of rims that does not require wheel spacers.

You are far better off going with a wider wheel with the correct width and offset. This will allow you to maintain the carrying capacity of the truck, since they are properly sized and designed for the larger tires you intend to run.

Conclusion

Going bigger tires might look awesome, however you want to limit how big you go, especially if you still want to maintain full functionality of your truck. Bigger isn’t always better since the bigger you go, the more modifications you’ll need to make as well adjusting your speedometer reading. For the best all-round upgrade we recommend not going bigger than 37”
