mini spare

ok so i kind of feel a little foolish askin, but would feel more foolish driving. whats the point of having a lifted jeep with 33's or 35's and then the big ol stock 30" spare? i mean not everyone does it but i see it around quite a bit. is there any benefit of carrying around a tire that you can't use, or do these people carry them incase someone in a stocker gets a flat on his spare? or can the mini spare be used?

Hilarious. I never got that either. I have 2 sets of tires and wheels 31's and 33's both with full size spares!. Ya know else bothers me is that when companies say like Pro Comp run deals: buy 3 get the fourth free.....what about the fifth! Idiots

Thats cause most people do not think about there spare that much I have 33s with a 31 spare because I value my tailgate more than getting home Nauh really the 31 will work fine to get me home as long as it isn't going home in 4WD! the smaller spare can be used as long as you do not have to use 4WD.Besides hanging anything larger than a 31 on your tailgate without a bumper mounted carrier is just asking for trouble.

I took mine off when I put my 33's on. I thought it looked ridiculous. Plus, now I'm starting to like the look of a Jeep without a tire carrier.

I actually had this problem on sat, wifes ZJ with the LT235's got a flat at the store while she was shopping, in the rear, brand new tires, picked up a piece of steel about 2" long, looked like a concrete nail. Flat was in the back and thats got a locker in it, her stock spare is a P215, seeing as how I did not want to grenade the rear I pulled the spare out of my XJ and put that on.
Got to run out tomorrow and mount and balance one of my 50% BFG AT/KO's on a spare canyon wheel and put that in the ZJ for future just in case use.
The TJ's all have 30's and I have two complete mounted sets of 4 in the shed on canyons so thats not going to be an issue with them.

my jeeps had a 33 inch spare and a custom high lift holder on the tailgate.. its been on for 4 years and never had any problems with it.. having a smaller spare it pointless.. when you on the trail and need a spare a smaller tire isnt gonna cut it... if your afraid of breaking your tailgate with a 33 then get one of those bumpers with over sized tire carrier... having full size spare is the smart choice.. i have a bud who has a full size spare thats a cheaper tire but it will get the job done in case of a flat..

To answer the question at large, I assume it's as people are upgrading in stages and forgo a "fit spare" so they can afford a winch, gears or petrol. Some on the other hand, bought used and either didn't notice the difference, or haven't felt the need to fix it yet.

As Rich ran into and SLF mentions, if you have a mismatched spare and have to hang it someday, treat it like one of those fake tires you get with small sedans.

Run with mismatched in 4x4 (locked) and you will destroy the drive. Run with a mismatch in the rear with limited slip...well I don't know what would happen, but prolly not a postive outcome. Us (TJ and older anyway) folks don't have to worry about ABS, but I'm not sure how that system would react with mismatched tires. Common sense tells me that as the ABS is monitoring all 4 wheels individually and keeping them from locking up, then a different size tire in one quadrant would naturally push or pull (depending on if it was larger or smaller) across the x/y of the vehicle. Not necessarily a deal breaker, but I wouldn't want to have to fight that problem during a high pucker braking event.

I had the same problem Rich had a few years ago with a used truck. Got a flat and THEN found out that the spare was from a different bolt pattern vehicle. I check now...

I get pissy when I can only get a "deal" on 4 tires too. Stupid marketing people I guess.

Thats one of the reasons that if you buy a car with ABS it comes with a full sized spare and not a donut. And ABS was an option, I know a 97TJ that has it. I have also seen SE TJ's with donuts on the tire carrier from the factory the owner told me he ordered NO extras including a radio so it also had no antenna. The dealers always order them with radios and normal spares because they just look plain silly on the lot with that donut hanging off the tailgate.

I just got my jeep(1999 wrangler)it had 31x10.5 on the road but a 30x9.5 spare. UGH who ever had it before was either ignorat or cheap but I replaced the spare with a 31x10.5 this last weekend, though it isn't the same brand as the road tires.
So IMO it is ignorance of not thinking of the spare. If the size differance is such it will ruin the jeep. Ask them sometimes

cheers

I stand corrected. I've never seen a TJ with ABS, but that don't mean they don't exist...Wonder why Jeep got on that bandwagon? I don't see ABS as a positive in TJ's.

I have seem em without radios tho...most of the old postal vehicles were like that too.

No, I think it's more a matter of money, $500 set of 4 vs $650 set of 5. Also most don't think about it and unless you have a traction device really does not make any difference to get you home or to a tire shop. With a traction device it's a different story, basically one wheel spins more than another so it stays locked which can eat a LSD or break a locker.
