hmmm....good to know. hard to understand how 1/8" difference in tire size would ever cause a transfer case to explode but no worries here as my tires are new and the same size all around lol.
no need to be sorry. i'll def keep all this info in mind.Dont look at it as 1/8" difference in tire but look at that tire in Revolutions per mile. If that circumference is say 320 revolutions per mile and the 1/8th" off is say 317 per mile or even 310..... that 10 full revolutions of "slack" needs to be asorbed in the drive train. Granted your not driving in a straight line all the time for miles on end, but turns will factor in to even it out, as well as breaking, dirt/sand in roads ect. Also with a wrangler/pick up the transfer case has either gear drive or chain drive, so there is ZERO room for slippage. where as in a awd car or high end suv like a Grand Cherokee or say Acura MDX the "transfercase" or "power transfer unit" has an over running clutch which though hydraulic pressure allows the rear differential to compensate for this difference and allow a larger tolerance difference from front to rear axle tire diameter.
Sorry to break out the tech but its needed to explain this.
