How important is an exact match spare?
So I am planning on attending the West Coast Camp Commander (as long as the work gods cooperate). Since my last major 4X4 adventure I have added some mods, and as I am sure many of you can relate to, ran out of funds.
I was looking for a good way to mount a spare, still use my enclosed roof box, and tow my travel trailer. This did away with my thoughts of throwing the spare in a roof basket, or using a hitch mount spare tire carrier.
I measured the old stock tire mounted in the factory position under the rear and found it to be 29" in diameter. My brand new tires post-lift are 32". Since I am currently out of funds, and still in need of a great alternative form of transportation for a full sized spare, I came up with the thought that maybe, just maybe, 29" is close enough to full size for the purposes of a spare.
I haven't had a full time 4X4 before, so I am not sure how that kind of drive can be affected by a couple inch difference. I am sure someone out there is the type of person who likes math waaaaaaay more than I do (doesn't take much for that to happen) and will know something about how many rotations this difference becomes, how that affects the gearing, etc, etc. Those are just the potential things I could come up with, wouldn't suprise me if there are more.
The best things in life can not be found on a map; they can only be found while Wandering.
