255/80/r17s pizza cutter thread

Lifts aren't going to necessarily decrease mpg's. The only reason lifts typically decrease mpg's is because people upsize tires (read: add more weight and rolling resistance).

 

Rear no, front the usual = fender trim, pinch weld, cab mount chop/relocate.

 

Do most go with the same size Pizza cutter spare under the back of the truck? Do you have to bash the metal tab out a bit to accommodate the larger size in there?

 

Not me. Waste of a perfectly good spare, that I may never use....

 

I’ve heard it’s possible to fit it under the bed, but I keep mine in the bed due to laziness and the fact that it can get trapped under the truck it stuck situations.

 

Keep your original spare to begin with, as you wear out a set of tires, then put the best of your worn out 33" in the spare position. Your spare does not need to be the same size as what you normally drive on the road with, or off-road either. The spare is just to get you back home or to the shop.

 

Ah okay, makes sense. My tires are currently 265/70R17. One size up from stock. The original spare is a Hankook Dynapro HT equivalent in a 16” wheel. So I’d have to get a equivalent 16" tire to fit my current 16” spare.

 

No, I do not think it is making sense to you yet.

You have increased the size of your tires up one inch, from ~30.5" to ~31.5" +/- 0.5". Your spare is for emergency use, or simply to get you home or to a shop who can repair/replace it. There is no need to do anything with your spare at all. The difference is only a half inch of ground clearance, if you are running any trails.

My example: I will be running 35"x17" tires on the trail and *30.6"x16"and 33"x16" tires on the road. My spare is an old practically worn out 33" BFG KM3 which fits just fine, it is tight, in the spare tire position under the truck. In either case of a flat no matter what size tire I'm using on all four wheels, the spare will remain a 33" tire. All is very OK with that.

* In case you question the 30.6" tires; like you I'm a bit OCD and wish to wear out that original dismounted spare tire I still have so I am going back down to 30.6" before I install the 5.29 gears for permanent use with the 33" and the 35" tires.

Every tire selling person I regard as a friend kept repeating to me that I did not have to match my spare with the tires on the ground. I finally took their advice, as I am giving it to you here. To further drive this idea home there is an Association of 4-Wheel Drive clubs in CA that requires a spare tire to be within two sizes to go on one of their trail runs. You are within one tire size.

 

Okay thanks.
