Spare tire question...
Go easy on me yall.... I have a silly question.....
I recently upgraded tires to BFG KO2s 275/65/R20 from stock Bridgestone's 275/55/R20. It did not don on me until now about my spare tire size which is a an 18" Goodyear Wrangler. I'm not sure of the specks of the 18" spare but I know it can be used with the 20"s otherwise Ford would not have it a spare. I realize my spare can be used with my stock 275/55/R20 tires but I went up a tire size from 55 to 65 which is a taller tire.
Do I need to change my spare tire size to the equivalent of upsized 275/65/R20 or can the 18" stock spare still be ok with the upsized BFGs if I get a flat?
thanks!

I wouldn't worry about it too much. But when these tires go to get replaced, save one and put it on your spare. Someone correct me if a 34" tire won't fit in the spare location.

Thanks yall for your replies. I'm just concerned that if I DO have another flat (I did have a flat with the stock tires that is why I went with BFGs) the spare wont be tall enough.

I think I read on here somebody who put a 34" tire under there with no issue. But wouldn't worry too much about it, if you get a flat, put the spare on a front tire and take it easy getting to the shop.

Thanks yall. Since I really cant afford a new wheel and tire for the spare at the moment, is there an 18" equivalent tire I can buy and mount to the stock spare wheel so that will not affect the rotating components and also still mount under the truck bed? I much prefer to not risk damage to truck components as I cant guarantee I would be close enough to a place to get a flat fixed.
I apologize for all the questions but I greatly appreciate the feedback.

295/70/18 is closest, I think. Check tiresize.com if you want to look at tire sizes quickly.

I was trying to google off my phone and it's not very efficient. My numbers were an off the wall guess.

275/75R18 is 34.25" tall. Just a 1/4" taller than your 20's.
Edit, thats not a real size. 285/70R18 is 0.2" shorter than your 20's
