Will a 255/85/16 Fit Spare Location??

Anyone know if a 255/85/16 bfg-KM2 will fit in the stock spare location under the truck? (02 4runner) Thinking it might be a good idea to have a full size spare....

doubt it, its not the width of the tire thats is the issue its the height, I don't think the frame rails are wide enough and if you have a hitch I don't think its far enough backward out of the way to fit

However if your wanting to carry a spare but don't want to put it on the roof or in the cargo are, look at a CBI hitch mount tire carrier, it puts the spare on the back like the FJ but tilts down so you can still access the rear hatch, the only thing left to do then is relocate the license plate, and fro $20 at pepboys I can do that for you easily

get an OBA, or a power tank system, and carry a deflated spare in the stock location. :)

:hillbill:

i have OBA. Even if its super flat underneath it will still inflate right?
thanks!

I was mostly joking. But as long as it is on the bead, it will be fine if you want to risk it. maybe WAY udnerinflated it would work.

I wouldn't do it, Think about it, a 33" tire your inflating from nearly nothing in it, plus you don't have the pressure keeping the bead seated, if dirt get up in thre you could have a hard time keeping the spare inflated

i run my 33's on the trail with 11 pounds in them... you could probably keep a bead on with 7 or 8 pounds if it was just sitting under the truck instead of wheeling it.

the mounting system for the spare puts force on the tire sidewall as the rim is pulled up towards the frame, this could cause you to lose a bead over a few thousand bumpy miles.

for me, if this is a DD, an under or uninflated spare is worthless. for a trail truck, you can get away with it, but i wouldn't do it on a daily driver. usually flats happen at the worst possible times, and air sources typically fail when you need them most.

Everything in this post is why I was mostly joking about the under inflated spare. If it doesn't fit, which I don't think it does, I would look at a CBI tire carrier, or doing the 1st gen roll bar mod on the inside of your runner and making a tire mount there.

you joke about it, but i had many people suggest it to me back in the day, and i know a number of people do it. i keep my spare at 40psi, in case i had to change a rear tire when fully loaded (37-38 psi)

[04 Rocko Taco]

I keep mine at 42 psi. (max PSI on the tire) and figure I can let a little air out, but that way if it leaks slowly or anything under the truck, I should still be good.

I got a cheap nock of CBI from amazon (it dosen't tilt) but I had to have my spare and it was making the truck to top heavy on the roof and I needed the cargo area for my other crap so I put it on the back and it works great for now, I have long since removed the spare tire carrier mechanism due to I welded the hitch as a rear cross member in the back.
