Since I had to lower my spare to install my exhaust today, I thought I'd check the air pressure in it. It's the first time it's been down since I bought the truck. To my surprise, it's not the same size as my tires. My truck rolls on 245/75/16. My spare is a 235/70/16. I know cars have had "donuts" for years, but I didn't expect the factory to put an odd-ball size in for a spare on a truck.

 

At least you got a 16" wheel. My truck came with 16" Alloys from the factory and my spare was a 15"... bah..

 

same as me

 

that sux, my truck had a full spare with a 16

i have a stock 245 75 16 spare if you want it...25 + shippin
tire only

 

acully alot of trucks came with tons of odd sizes

 

i had 245s stock..on 16s..spair was 235 on 15

 

my spare size is 225/70/15

 

be happy u got a spare at all, my cousin picked up his new F150 and when he did his oil change he noticed he didnt have a spare LOL

 

I had the teardrop 16's 245/75, the spare is a 235/75R15 (or is it 235/70?)

Anyway I had to use it once.. its odd driving with a crap puny rt/s with
3 toyo 265/75r16's

too bad the toyos were on backorder too ended up with 4 new tires.

 

I don't know what the hell mine is . Afraid to look . Some kinda doughnut . Wasn't a big issue before though . I couldn't get the wheels off . The previous owner put gorilla locks on the wheels ; and either he didn't leave the tool for them or the detail people at the dealership took it out . I welded nuts to the locks and removed them and replaced them with stock L-nuts . The dognut spare is useless anyway . I need a real rim or two , maybe 16's to hold a big enough skinny tire .

 

My spare wasn't right either on my old truck. Don't know what it is on the new truck. Probably should check that out.

 

They come that way from the factory. This is part of the problem of haveing a 20 year old fram rails. There just isn't room for a bigger tire. I have a 235/70r16 as my spaer and there is barely any clearance for the exhaust to run by. Not to mention it literally touches my Hitch too. When I ran my dual exhaust I had to wrap it to keep the heat off the tire.

Exactly the same setup as is on my truck.

Maybe someone else can elaborate, but I thought it would wear out the clutches on a limited slip differential by running tires of different sizes. I would think that it could cause some serious damage to the Torsen differential in the L2.

In the owner's manual for my buddy's RX-8 it says to move a good tire from the front to the rear, and run the donut on the front, in the event of a flat in the rear. I haven't found anything along those lines in my owner's manual, but then again, I haven't looked for it either.

About a year ago I read where someone on this forum successfully got the dealer to put a 31" BFG on his spare rim, at no cost, since he had the FX4 with 31s. I had previously heard that it wouldn't fit between the frame rails, but I guess I should check it out for myself...

 

They intentionally mismatch tires and wheels on these to make themselves more money. If you blow out a tire they want you to buy a new tire not take your spare and use it forever... Ford has an amazing way of doing that. GM did too when I worked there but the Dodge trucks at work all have the correct size spare so I don't know. The only cool thing was my spare is a 245-70-16 which is plenty close enough to what I have now to use.

 

i had the oem 15 inch wheels with a 16 inch spare

 

Well damn. I thought I just got screwed. I didn't know they were doing everybody.

 

Trust me it won't work on my truck. I will take a pic when I get home. It is veryclose to the exhaust and it is literally touching the Trailer hitch. I have emergency roadside assitance and road hazzard warranty with my tires. Unless I am in an Emergency that spare will never go on this truck. I will have it towed and a new tire put on or the old one repaired for free. The funny part to me is, My 01 Off-Road package had 16" rims and a 15" spare. My level II has 15" rims and a 16" spare. That is just awesome right there!

you guys are lucky to have a spare i have no spare compartment i hav to keep it in the truck

 

I got two brand new Goodyear wranglers one is on the truck right now with the steel rim.

My 245/75/R16 is STUFFED up under the bed, looks like it needs a coat of wd-40 to slide it out.

 

Didn't know Ford was in the business of selling tires..

..You don't suppose it could have anything to do w/ saving the customer money by not including another expensive alloy wheel or another expensive large brand name tire, do you?

Here's your tinfoil hat dude..

 

Not to mention when I was working at valvoline, Ther was a store a few miles from me that was caught stealing the tires off the bottom side of the trucks that were coming in. They would keep them until they had a complete set and them sell them off for a profit. On a side note We have a burnout Contest at my churches Carshow every year and My buddy scott collects tires that have fallen off the bottom of our trucks and uses them for the contest. I thought he was nuts when he told me he picks up brand new tires of the side of the road all the time, but I have noticed them a lot more since he mentioned it. The cables that hold it up there get rusty and they finally snap and boom! he has a brand new tire. He is a truck driver so he is on the road alot more than most of us.
