spare tire

Hey everyone - I am putting 31X10.5X15 tires on my 1997 Jimmy and currently have the spare tire up underneath on the cable setup. My question is do I have to get a full-size spare tire or will the "doughnut" work? I think that I need a full size spare, but I am just being cautious. Will the 31" spare fit up underneath on the cable, or do I need to mount it on the outside of the vehicle? I could get a rear rack like a ZR-2, or I could mount it on my Thule roof rack, but I would like it underneath for convenience purposes. Thanks for the help, Scott

Re: spare tire

Personally I wouldn't trust a doughnut at 55 mph with 31's on there. Too much of a size difference. Just see if you can find a larger doughnut if it will fit underneight there. Otherwise you don't need to get a good spare just an older 29-31 incher that holds air.

<font face="Comic Sans MS">If you have a limited slip differential make sure you don't even consider running mismatched tires on that axle...

Re: spare tire

Would it be safe to put the doughnut on the front? I know that it would not be smart on the back, but would it be ok on the front? Thanks for the help!

Re: spare tire

Under the vehicle is my faveorite place to keep a spare tire..[img]/wwwthreads_images/icons/wink.gif[/img] Just think when your in a high angle rutted road and boom!! a tire blows.. You get out and look at the rear of your vehicle and the rear end is basicaly under ground bottomed out.. I dont even thingk I got enought room to fit the jack under there.. Hmmm what do I do now.. I love it too when your in a water crossing and get stuck and need an anchor to tie your Pull-Pal onto.. Thankfully I have that spare radiator hose I can use as a snorkle.. Then going with the size part of you question, if you blow one on a run and only have a doughnut to replace with, your froading day is over.. Turn around and go home.. But to end all this it is fun getting a ~90 lbs 33" spare off your roof thats 6 1/2 feet up..[img]/wwwthreads_images/icons/laugh.gif[/img]

Re: spare tire

Thanks for the help. Would it be ok to run the doughnut on the front for on-road use, or would that cause wear to drivetrain components? Thanks again.

Re: spare tire

I noticed a lot of times in my trips to the junk yard that there are many lifted (lifted in many weird ways, i seen a block of wood for a body lift) s10s that have 31s on the stock rims. i haven't gotten around to asking how much they want for one, tho i do need one. but what im saying is go to the junk yard and see if they got a used 31" tire on an s10 rim, or even just a used 31 and have it mounted...
just my $.02.... don't know about drivetrain ware with a donut

Re: spare tire

I'll be damned if I"m going to ever mount my spare underneath the vehicle. On my way over to my sisters wedding i blew a tire. Of course i was in dress clothes and it was rainy and muddy outside. I keep a real flrro jack in the truck so that part wasn;t the problem, but the spare hadn't been used in about 10yrs. all i ever did to it wsa check the air. I spent about an hour with my leatherman to cut off the framework that holds it up. damn near missed the wedding. now a days the spare is always in the bed.
