Front Alloy on rear

[Tarkuk]

Hi all

I am looking to refurb my one of my rear alloys which is Mission E, i know the rear offset is ET66 and the fronts are ET60, i do have a spare front alloy (ET60), can i use that alloy on the rear until the original rear is refurbished.

Thanks

I would not do it just in case the fitment is wrong and you screw the suspension or catches something. I have used a loan 1 20" wheel while one of my 21" was getting refurb

No.

bummer, there are so many front alloys available but rear ET66 Mission E are so rare

I was thinking of using fronts on the rear as ('jacks' properly bolted on but with the car stationary all the time) while I clean the rears, would this be OK?

This is exactly what I do as a "spare" situation. I have an extra front mission E wheel with tire sitting in the garage, when when my wife gets a flat, it goes on either front or rear until we can get a new tire mounted.

The fronts are ET60, which means they sit 6mm further out then the rears, and they're also a narrower wheel/tire, so that provides even more clearance. I've had no problem running a front on the rear for a few days (it just looks a bit funny, especially from behind) until a new rear tire could be sourced. The actual stats are 1" more clearance to the inside, and .6" more clearance on the outer face.

If you run the specs on a wheel size/offset comparison calculator, the circumference is 88.6" for the stock rear, versus 88.9" for the front setup. That .4% difference has never triggered any sort of stability warning or other issue with the sensors for me. It's a 2 revolutions per mile difference.

Is that true for 20” and 19”? I would love a spare. Maybe even non oem for those exact situations and when a single alloy needs refurb

The ET is lower but so is the width of the rim/tire so I don't see any reason it wouldn't fit.
The rear brakes are much smaller too.

Just try it and see if the rim doesn't touch anything.
I assume you're not going to drive like this?

You can drive like this, we have for multiple days at a time. The rim/tire has more clearance in every direction, and the circumference is close enough it doesn't set off traction control errors from the slight difference.

I'm out right now, but I'll run the numbers for 19" and 20" on a wheel offset calculator. It should be the same result but always good to check.
