LOST JEEPS :: View topic - spare tire max size

that sounds about right but I don't see why a 265 70 16 wouldn't fit cause they're the same diameter but obviously wider

Back in June, I had and posted having 245/70R17 (nominal 30.5" OD) MT/R installed on the KK's spare rim and it fits within the area underneath and it fits fine, although snugger than OEM.

E2: What lift do you have or are you planning on going with?

IMO, rubbing and gearing are probably more significant issues when going to a 31.7" tire.

I would just leave one of your existing tires under as a spare for normal driving. Although not ideal, it will get allow you to go a short distance home or to a tire shop.
Then when you are going on long distances or offroading put the 31.7" spare on the roof.

Because of the rubbing and gearing issues, I decided to go with a JBA 2.5" lift and LT245/75R16s for now. So, my spare fits underneath, but when I go offroading I still plan on putting my original stock spare on the roof just to be double safe.
I blew a tire on my last offroad trip so I had to put on my spare so effectively drove with no spare the remainder of the day and it made me very nervous. :shock:

if youre goin ATs and not with a 32 i would just go with the 265/70/16, theyre about 31x10.5 and what i run. when its time for new tires ill see if a 265/75/16 fits under there, but that could a while, or i could decide to upgrade to MTs but im sure someone will try to make one fit by then

I have just under 3/4" of clearance all around my stock P235/65/17 (29.0" diam) spare.

I didn't have any problem mounting a 245/70R17 Goodyear MT/R down there. See also this thread which contains: MtnLuvr wrote: Back in June, I had and posted having 245/70R17 (nominal 30.5" OD) MT/R installed on the KK's spare rim and it fits within the area underneath and it fits fine, although snugger than OEM. If you're thinking about 32's like I believe I saw in another post, then you may have some challenges if you have the OEM tow hitch and maybe also near the heat shield. You could wait and do what I did which was get the tires I wanted installed on the 4 corners and then I test fit one of them up in the spare well to check for clearance before I went and had one installed on the spare rim. Hope this helps.

Yeah I don't really want a tire of top of my roof and for sure not on my hood. So if the next size down from a 32" is a 31" for a spare I take it that is still a bad idea! So I want the 235/85r16 A/T a 31.7" tire, but looks like a 245/75r16 a 30.7" tire is the max size that fits as a spare underneath. So do I go with 31s?

I blew a tire on my last offroad trip so I had to put on my spare so effectively drove with no spare the remainder of the day and it made me very nervous. Okay Okay I am getting the 4" JBA lift. As the plan was to get this liberty off the ground as needed clearance with or without the more clearance larger tires will give. If I can get a way with 245/75r16 I could just go with all 5 tires with this as my tires size. If I go with 245/75r16 then I may go with the mud for that slight extra size compaired the A/T on the BFGoodridge brand. But this is my daily driver so A/T should be fine as I life in CA where the mud? If I go with the 235/85r16 then the spare could be the 245/75r16 so not 31.7" tires with a 29" spare it will then be a 30.7" spare, better but not the best. It's just a 235/85/r16 will not allow me go into parking garages as my daily driver. By the way I have the automatic KK so the gearing should be based on that model. So where is a 32" tire versus a 31" tire for off-roading really needed. What does everyone else have?

if youre goin ATs and not with a 32 i would just go with the 265/70/16, theyre about 31x10.5 and what i run. when its time for new tires ill see if a 265/75/16 fits under there, but that could a while, or i could decide to upgrade to MTs but im sure someone will try to make one fit by then

The white and black looks good. Yeah the 265/70r16 are slightly taller than the 245/75r16 by about .3. Having a wider tire to me means less mpg and these liberties are not the best mpg. My 93 truck gets the same when I drive it hard or better mpg if a drive it without my lead foot as it is a 4.3. So based on what I see most people have the 245/75r16 or the 265/70r16 not 32's the extra taller tires would help, but that much?? if I go with everyone who has 31's then really having that tire would keep me from leading for following. And then I can stick it underneath. When I got a a week or so before I get my lift. Yep V2.0 JBA's are going to ship the end of next week. So 32's or 31's is the week challenge...................

im going with 265/75/16 when I get my jba in also. I want to wait a while and install other stuff first since my tires are new anyway. need to get my locker and gears in first cause you will need gears with a 32in tire. if it doesn't fit underneath ill just buy a rack and throw it up top when im out wheeling. unless you plan on changing gears you should stick with 245/75 anyway, even if a larger tire will fit underneath.

Post subject:	Re: spare tire max size
why are you guys so worried about the spare? Theres more than enough space behind the driver seat to trow a 44'' spare for the few times your gonna wheel it. dont select the tire size based on what you can fit in the spare area

Post subject:	Re: spare tire max size
A spare is like underwear. Maybe not, but good to have but not needed. I could throw a spare inside but that not normal and when done takes up lots of space. Being on la I am often finding myself in parking garages with 6'8" clearances. So a roof rack with spare on top would not fit. If the lift alone with the larger tire did not fit than it would not matter but I think I can fit so I worry as I can.

This is what it would look like with a roof rack and spare (245/75/16) on the roof of your KK (this is mine) and a 3.5" RK lift:
