Re: Compact Spare Tire - '06 Overland
If you have QDII, all 4 tires need to be the same diameter. I dont know how far you could drive on that before damage would occur, but even one new tire of the same type will cause damage, if installed with 3 existing tires that have some wear. I had an unrepairable sidewall puncture and had to buy a new set of 4, even though the other 3 had less than 20k. 3/4 of an inch is a huge difference, and not worth the risk of very costly damage, and getting stranded.
