Need some schooling on tires/wheels

[tuckerdog1]

So DW curbed the LF rim on our 2015 5.0. I saw this as a good chance to replace a rim & use the curbed one as a full size spare. Looking on Ebay, noticed they were listed as front or rear. I thought they were the same, but I guess not. Only difference I could see was an offset difference ( 40mm vs 48mm ) per the listings. So I'll for sure get one listed as "front". And to help with getting the new "full sized spare", to fit in the recess in the trunk I suppose I should go with the 245/40 vs the 275/35. My question would be, any issue should I go this way, and have a rear tire flat? Don't think so, but best to ask.

Thanks

You obviously have the Staggered setup with the wider rims on the rear. I'd be keeping a front spare in the trunk which will suffice should you have a rear flat, but make sure this would only be temporary while getting the rear repaired or replaced. The front on rear will be recessed more into the wheel well, but the diameters are the same so you will be fine.

Thanks, thought that would be the case, but sometimes what seems like a no brainer turns out to be dead wrong.

Does that mean you can't use the front on the rear?

This should be of help to you:

Our Gennies came with either the standard 18in wheels (3.8) all the way around or the staggered 19in setup (standard on the 5.0) with the rears wider. Since the tire circumference is the same you shouldn't be hurting anything running a front in the rear, but aesthetically it will look off. The higher offset on the rear is due to the wider rim and aligns it properly with your wheel well and fender. Using the 245-19 as a spare is perfectly fine; if a rear goes flat it should be repaired and swapped back relatively soon regardless.

Personally, I like the staggered setup and will be upgrading my 18's to 20's after the first of the year.
