37's with 35" spare

Not wanting to buy a 5th 37" tire and rim to use as a spare, I am wondering if one of my 35" winter tires could be used in case I rip a sidewall and can't plug it?

I am running an Aussie Locker in front and stock limited slip rear. What would do less damage with the smaller spare? Front or rear?

It would be for unreparable damage to a tire- just to get me out of the woods.

I know it isn't ideal but can it be done without detroying anything?

Thanks

Pressure it up to the max it's rated for, put it on the back and try to get the tire heights in the back as close as you can by airing down the taller one. Measure from center of the axle to the ground.

Driving with a different size tire is not recommended with either Aussies or limited slip so just go out of the trail till you get to a place the tow truck could come.

Thanks!

I read somewhere that tire pressure makes no difference- it's the same distance to make one revolution no matter the pressure. Does it make sense?

The dynamically loaded radius is the only thing that matters. You can under inflate a 40" tire to have the same radius as a 35" tire so they have the same rpm per a given vehicle speed. Pressure does matter because you have to reduce the pressure in the larger tire so its radius matches that of the smaller tire. Always measure from the ground to the center of the hub to get the correct radius.

Makes sense. I'll stick to the 35" spare. Thanks.
