Just picked up an 01 F150.

Anyway, it's got a non-stock dual exhaust system on it, and the full size spare doesn't fit under the bed. I'd rather not have the spare in the bed even tho it's got a tonneau cover.

should I try to go with a 15" spare? Do they make a mini spare for trucks like the do for cars? thanks....

 

No because a 15" wheel will not fit the truck. If the stock tire will not fit and you absolutely don't want it in the bed, you can find a smaller tire that will fit your rim, make sure if you have a flat, to put it on the front and not use 4x4, assuming you have a 4x4.
Or put a stock style exhaust put back on.

 

yea it's a 4x4. I assume it'd be OK to put it at any corner, just to get me back home and get the regular tire fixed. Anybody know offhand the smallest tire that'll fit on a 17"? Guess it's time to grab the tape meaure and crawl unde my bed....

 

No as stated before it would not be o.k. to put the smaller tire on any corner just to 'limp home'. Make sure that you take it out of 4x4 and put the smaller tire in the front, even if it means to replace a good front one onto the back...just as long as both the drive wheels are the same size (this will not confuse you diff and cause many more problems.) Where was the spare before in the bed? I have a Di/Do exhuast and I fit a full size spare underneath, i wonder who did yours to not allow you the same luxury?

You could always bring the truck in to a exhaust shop and have some new pipes bent so they go around the spare.
