Max tire size on stock 2500

[ERK]

Anyone put larger tires on a stock 2500? No lift/leveling. Stock rims or aftermarket? How big did you go? Any rubbing?

Gonna be the same as the 4th gen HD's, might wanna check out that section, or the HD rams forum too.

do you have a sawsall ?

Our sister site. You will get much more HD help there.

This really depends on what you are using the truck for and really is only limited by the front tires.

295/60R20 is one I have heard. Which would be 295/70R18.

I would guess right about 315 would be the max.

If you stay on pavement you can go to the big side...if you go offroad a little smaller.

And then, there is, the sawsall.

Good luck

325/65R18 only rub at full lock on my oem wheels.

I'm running 285/75-18s on mine. No issues whatever. Stock wheels and no lift/level.

What did it do to the speedo/trans etc???

 

[NordicNevs]

I bet the Speedometer still reads as it did before the tires and the trans I still happy. Not that much bigger of a tire over stock.

I’ve got 285x60r20 stock tires on my 2500 Longhorn mega cab. I would like to go to 35x12.5r20 tires. I’ve had several people tell me that I could go with the bigger tires stock, no lift or leveling but I don’t know of anyone who has done this. Anybody out there put 35s on a stock configuration 2500 suspension?

Mine are essentially a 35/11.50 and they do not rub.

My odometer is off by 5% and the speedo is off by 3%. I just live with the difference.
