I've been researching maximum tire size for the stock spare location and some have had success with 265/65/r18 fitting in the spare location while others have not. Mostly depending on tire brand. I wanted to get Michelin Defenders in a 265/65/r18 size this spring, which has been shown not to fit. Would removing the hitch allow for more space and the spare to fit without rubbing KDSS? thanks.

Removing the hitch would give more room
i have 265/65/18 Pirelli A/T Plus and it fits

WAGX

thanks, do you have the hitch on your truck? Does it touch the KDSS?

I have a 265/65/18 Pirelli All Terrain Plus and it fits with a good amount of space with the factory hitch

Both my factory hitch and the tires are for sale currently lol

just looked into the Pirelli’s. Some members of the forum have done research on revolutions per mile on several tires affecting fit in the spare location. Looks like the Pirelli’s and Michelin’s have nearly the same revolutions. I hate to ask but could you take some pictures showing the fit of the spare? Thanks!

Just checking back if the 265/65/18 pirelli scorpion plus fits the spare tire with factory hitch?

"Factory Hitch" has different definitions ... there is the Class-3 "Receiver" Hitch and the Class-4 "Full-On" Hitch (that also attaches to the frame side rails). The answer to your question is different based on the specific hitch.

Class iv hitch. Part number PT228-60140.

I have Falken Wildpeaks in the same 265/65-18 size. The spare fits with no problem, no rubbing anywhere, but the Curt class III hitch does not fit with the bigger spare. But since it's only 4 bolts, I'm keeping it and if I ever do need to tow, I'll just remove the spare and bolt the hitch in.

Thanks...will stick to the stock size.

For others searching.. I run 265/70/17 Falken Wildpeak E-rated tires and it baaaaaarely fits with the Class IV hitch. Had to kind of kick it as I pulled it up into place.

Not exactly the same but for reference:

TLDR: 265/70/r17 fits but you might need to move the hitch some.

klinquist

Yeah, I tried moving the hitch... still ended up grinding a little “nub” off of the inside of the hitch just a few mm. Even tires of the same size will have slightly different diameters, and every mm matters . That’s why I mentioned the E-rated Wildpeaks - I know they have more tread depth than the SL-rated ones.

I can confirm 265/70/17 wildpeak at3 will fit in spare location with the curt hitch...if use smaller washers on the two forward in car bolts, and not the ones supplied by curt.

Just chiming in to report that 265/65/r18 Pirelli Scorpion Plus fit with the Curt hitch/receiver.
