5th Gen Ram Bighorn stock max tire size fitment (no mods or upgrades)

[PickupMan]

I'm looking for confirmation from anyone who has installed 33" tires on a 5th Gen Ram 1500 bighorn with no modifications done. There is a lot of unclear information and/or confusion regarding the specifics I mentioned, so would greatly appreciate feedback from anyone who's actually done this, whether the install was successful without further modification or not. Thanks!

*Please do not comment unless you have direct experience with the specifics I mentioned above

Does your truck have the off road package? If so they will fit no problem. No mods here and my truck clears 35 x 11s with no issues with factory off road package.

275/60r20 will fit no problem. Thats equivalent to 33” tire.

Rebel take offs are 33 X 18. Good deal if you like those wheels. Some 18's fit, some don't.

I have a stock ride height Bighorn with 275/70 r18, they measure 33.2 x 11. Only modification was recalibration of the speedometer with a Hypertech programmer. It was off by 2~4 mph before recalibration.

There is no rubbing, plenty of room, could probably go 34s but might need to trim or zip tie the plastic fenders liner out of the way

Agree with stock rims this will fit.

you can fit a 34.3X11.2 with the help of a heat gun on front wheel well liners.
