Mismatched spare tire?

[Skid51]

Anyone with 37’s have experience running a 35“ spare? I imagine you’d be ok from a handling and safety perspective to use one to drive, temporarily and conservatively, to a tire shop but is there risk of grinding the rear LSD on dry pavement if rear tires are mismatched in size?

I would not run mismatched in the rear. Front temporarily will hurt far less

I'm not quite at the point where I will get new tires, but I've been going back and forth between 35 and 37. Would you think there is a chance that a 37" spare would fit under the bed if it was deflated quite a bit (with the assumption that I have a solid compressor to air it up if/when needed)?

I do not know to be honest. My spare sits in the garage. I think some have gotten it to fit by removing the heat shield but if I remember correctly it’s the hitch you hit with a 35+

Thanks! I'm thinking the play may be like you suggest, where if a rear tire fails, swap out a front tire and put the spare on the front.

It was all we could do to get a 35 inch spare under the bed. 37s no way. If you go 37s get a 35 inch spare. You have a 50/50 shot that the front tire would go flat. Whichever tire goes flat run the off size on the front and don't run in 4x4 until you get it fixed.

On road, actually greater odds of a rear flat. Front tire rolls over sharp object that is laying flat and kicks it up, rear tire rolls over it as it’s bouncing and gets punctured

Offroad, I think higher odds of rear flat as well, since you pivot around rear tires it might be more likely to catch a sharp rock in the sidewall

Please give us the exact percentage on rear vs. front flats.

More weight on the front helps the front get the puncture. I have yet to puncture a rear tire its always the front

X %F : 100-X %R

I honestly don’t know, it’s just what I’ve read and it makes sense. And On my bike I know I get WAY more rear flats than front flats.
