As my sig says, I have 32x11.50R15 tires. I currently have the OEM stock tire. I desire a real spare that will fit under the bed.

I've read that a 31" tire fits under the bed. I've also read that a 32" tire w/ 50% tread fits under the bed. Using a spare like this I would need to deflate the opposite tire to level out the truck.

I'm thinking of getting a new 32" tire and using that as my spare. Since it wont fit in the spare tire spots, I figure I can just deflate it to the 31" tire size and shove it under the bed. The benefit to this would be that if I get a spare, I could drive to the nearest gas station and pump air into the tires and be at 100%. Or, on planned offroading adventures, I could bring a portable tire inflator with me.

What do you guys think of this?

Oh yeah, can my stock jack still extend enough to lift my truck off the tires?

 

i think a 265/75/16 will fit under the bed.

your spare wheel is 16x7 anyway. that tire size should be enough anyway.

do you have a rear limited slip? if not a 1" tire size will not matter that much.

 

Hey man, just get a used 32" tire. If you need rims, I know of some cheap places here in Los Angeles that will sell you a rim for like 15 bucks. Try craigslist for the tires. I got mine for 20 bucks!

 

why does a L/S matter to what size tires fits under the bed? the rear diff is the same size weither you have an open or L/S diff.....

a 32" tire would be tight.....my stock 31x10.50x15 was pretty tight......and if you have or plan on adding a hitch, it will be worse.....my 31" barley fit with the hitch on it...

 

Jared fit a 33 under his, I plan on fitting a 33 or atleast trying lol. I am going to make it work one way or another. With the LS you have to have the same tire size or it will burn up the clutchs.

 

A L/S makes a difference when running two different sized tires. They will want to turn at different speeds and lock up the L/S. Which will wear the clutch packs out.

I have a used 265/75/16 under my bed.

 

ahhh yea i forgot about that...

 

Thanks for the tip Larson. I'll keep an eye out.

I'll try to re-state my idea....

FACT: a 31" spare fits under the bed
FACT: I have 32" tires
FACT: I can purchase a portable tire inflator
QUESTION: Would it be a good idea to purchase a 32" spare tire, and deflate it an inch (to the 31" size). Thus allowing me to inflate it to the 32" tire size when I have access to air (from a gas station or a portable tire inflator).

 

Tommy ideally you should find a used 32 to keep as a spare underneath. Thats what I have. Mine is a stock tire off of a F-250 and it fits under fine.

 

no need to deflate...

 

you will fit it.
i could prob put my 33 under if it wasnt for my exhasut

 

Do you have a hitch?
My hidden hitch won't even let me fit a worn out 31"

 

I have the uhaul round tube hitch, I believe it is equivalent to the hidden hitch.

 

i need to take another look at mine, i have a hidden hitch but it is the same width as the frame rails, i can't even get a 235 up there, i think the biggest i can hold is a 215/75
