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.

 

mounted 255/80r17 over the weekend, coming from LT265/70R17 lrE, the new size doesn't feel noticeably slower. These falkens feel more comfortable than the KO3s they replaced, not sure if it's due to the narrower profile (more flexy) or the compound. They have the same load range E rating. They definitely rub with 100% stock setup, however, after cutting just the corner pieces of the plastic trim behind the front tires, they are now rub free from daily on road driving.

 

Super nice rig, I do also have a 2015 Black
Still on air whether go for 255/80/17 or not due to the fact that it's commonly called skinnies.
I have my friend has Land Cruiser 70 series where he fits 255/85/17 doesn't look skinny in naked eye. But whenever I see the pics posted on internet with 255's they look sunk into the wheel well. I'm afraid

 

I agree that 10mm change should not give much of a difference. But what I doubt myself is why it looks skinner to the exact front view compared to 265/70/17. Any thoughts?

 

It’s all in what you want. If your concern is looks then yes I like the look of a wider tire better. If you want function? Skinnies work best around here in mud, rain, snow, and some rocks. This is only my opinion but I e had both work de tires and skinnies

 

Just put 255/80/17 Toyo R/T Trails on my 460

Last set was 34x10.5R17 KO2s


New set on the truck

 

How is the noise/ride quality of the RT Trails so far?

 

So far not appreciably worse than the KO2s they replaced but I need to play with the PSI a bit. Maybe marginally/slightly louder? Though I've been driving it with the radio off to try and get a feel for the sound with them new

 

Thanks for the feedback, I'm considering the RT Trails when it's time to replace my Toyo AT3s.

 

I've run the A/T IIIs before (albeit in 285/70/17) and they're my favorite tire that I've run, and the one I recommend most (based on both my and others' feedback). Very curious to see how the R/T Trails compare on and off-road.

 

Thanks
I do live in Canada with snowy weather so I do prefer 255's that also helps on MPG. I agree your points.
Only thing holds me; a way to keep tire edge sits along/ aligned to the Fender. Wonder whether spacers help but it also have cons more than pros
Thanks for the comments, helps a lot

 

As my first set of A/T’s my Toyo AT3’s have been good and trouble free. 265/70R17. I live in the PNW so I appreciated the siping all the way through and good wet weather performance. They were SL load. What load rating were your tires?
