How "functional" is a functional spare?

[microgoat]

Been wondering about this one for a while.

Can a 1.9 be a spare on a 2.2 rig?

Does the spare have to have the same OD, offset and weight as the other wheels on the truck? Or does it just have to have a hex?

Taken to its extremes, a foam TC tire could be considered "functional" although it doesn't look like much.

Scale handicap if you run the spare on course?

if i remeber correctly from last year it had to be the same size rim (2.2 or 1.9). dont quote me but i think thats how it was.. i'm pretty sure that it has to be able to bolt on.

have to be able to unbolt you're running wheel/tire and swap it out

Last year Ben let me count a 1.9 wheel with a Tamiya BFG as a spare for Guido (2.2 wheels).
My point was that even though it would suck to have to run it, it was functional. I could put it on and drive with it if I had to.
Who in the real world carries a 44" tall spare tire on the trail.

I was planning to do the same this year......I hope it doesn't change.

I also have a 1.9" Rock Stomper spare on a 2.2" rig running Losi Claws.. It's functional!

I would say functional just has to work. I think you should be shot if you put a TC tire on there for a spare though.

If someone has 44" tall tires, I don't think they even plan for spare tires... nor need one.

Order a few sets and we can sell them at the event.

I would add, should " reasonably resemble " the tires on your truck.

on a 1:1, you run 44" tires and have a 36-38" spare, as griz said.

if it looks like the others and bolts up and runs, we will let it slide, but I DO have the final say and I have been told I am prick at tech inspection.

Just at Tech?

Ban them all for not following the spirit of the rules.

[microgoat]

How's this for the spirit of the rules?

Back in the late 60's and 70's many cars carried a collapsible spare tire and air can to conserve trunk space. Looked a lot like the foam TC wheel.

If it was my event, I'd call BS at tech, but you gotta admit....

[chevy42083]

Heck, I think '80's F-bodies still used the inflateables. ;)

I need to look around for a collapsible 44

[STANG KILLA SS]

nope they had a donut. my 86 did. as did the 93, and 2000.

So now it has to look like the other wheels on your rig?

And tech inspection is based on how you are feeling that day?

I thought you had a solid set of rules we could just look at and go by?
