I'm working on a buggy build for KOH, and getting to the point where I need to do the tube work for the rear. I was thinking about putting a spare tire (or two) in the back, but a 40" tire takes up a lot of room! If I lay the tire down its going to make the chassis really wide, but if I stand it up its going to sit up pretty high. Either way, I think its going to look kind of stupid back there, and I don't want to make the rear tube work look like shit just so I can mount a spare. Anyone have good ideas or pictures?

There is plenty of room on the roof

x2, Jody's looked pretty good and might help balance the weight of the rig front to back for the high speed stuff???

This is how I would do it... A little lower center of gravity, but too low that you'll hit it in the rocks (too badly)
Jess, I doubt a smaller tire would be an issue. The high speed stuff isn't on pavement, it's on loose dirt. Tehre's plenty of slip with the dirt, and the tires unloading in whoops, etc. No real time to cause any bind, IMO. Besides you could just run the 37" a little more inflated than the 40 to compensate if you were worried about it.

That's similar to where Goat1 runs his spare (little wussy 37)

Don't you mean your new buggy?
I had no bad issues with the tire mounted that way, except you can't see out the rear view mirror. The weight really helped the car in the whoops at speed, but it was a little more prone to standing upright on verticle climbs. I could spin that car around on a dime in third gear with out any feeling of tipping over, but it had leaf springs on the front.
I am interested in seeing this thing since Jim and his crew have put a few bucks in it. Maybe they will need a driver for the MORE race they plan on running? Jim you guys should race it with JT in a hill climb...... Better yet let me race JT in a hill climb.

Looks like Poison Spyder might be using clamp on tire mounts...

I wonder if that would hold up to the pounding of whoops? Mine sat the weight on a tube and it would really be hard to get the mount off from moving down on the tube, when I wanted to put the ice chest rack on.

People have used similar clamps to mount hyrdo steering cylinders so I think the bolt on clamps would hold up fine. The down tubes may also be angled out so there would be no chance for it to slide down.

so with pits planned in 3 places maybe running a 33 x 9.50 would be trick to keep the weight and SIZE down to and could get you to the pits.
I still think you run for the win and a flat this year is a loss with the 3 minutes minimum needed to change a flat. I know Shannon got a flat, but he got really lucky they had a chase crew there.
While it is totaly doable, we ran from the last pit all the way in with a 35 on the right front and 40s on the other 3 corners. Scott had his hands full on the fast stuf.f I was watching 50mph on the gps and Scott working everything he had on the wheel to keep on the trail. Thats a big difference in size and I know CTM Jack ran one 37 from the same spot and said it was weird but no too bad. I would do it in a pinch but I'll have a regular size spare and one in every pit plus one or 2 in chase trucks in case we use a pit more than once, after the tire stuff I have seen in the OG and KOH 08.

Mount it to the rear axle! :dustin:
Yeah, I know, it's been done...I tried to figure out why but gave up.

I obviously see how quick and easy Jodys comes off (Strap).
Is everyone else just lugnutting theres to a plate mount, or is there a good quick disco way?
I have never been around the desert trucks to see their mounts, but from non-detailed pics you see some with a "V" looking handle sticking out of the tire. I have assumed its the hold down, but how are they doing those?
Large threaded piece with a nut with the big handles and you just torque it down holding the tire in place? I can build it just dont want to re-create the wheel or create in a vacuum and find out at miles 10 into the desert I lost my spare.

If you've got onboard air, or a decent sized CO2 tank.....
pull a vaccuum in your spare tire, and mount it collapsed on itself.....the size difference could be really significant, and assuming its on a beadlock, should be plenty easy to air back up.
In a rig w/ very little space, the little bit of extra room this affords may be worth the extra time it takes to air it up on course.

It's basically just a giant fabricated wingnut. Some guys make the wingnut male (wing stud) and screw it into the mount, some make it female and leave the stud on the mount and screw down over it, but same concept either way. Typically a large plastic washer is used, either stepped or tapered, to prevent wingnut-to-wheel-bore contact that would tear up a wheel.

Not really mine, just fractional ownership!
The spare tire mount that Jefe and Fat City came up with allows you roll the tire up and into position on the rear bumper to secure it with the V handle lug wrench. Our our first trip to the Hammers in it last month we put a heavy spare on the rear that would have been difficult if not impossible to line up without the rear bumper. We considered changing it out to run a set up similar to Everding's rig to keep the center of gravity lower, but as Jefe said, I never noticed it getting tippy at speed, the trail, or even on the 10 fwy. :grinpimp:
