Hi, just finished install of an Audi Q7 foldable spare wheel with wheel adapter, fits ok in the back but floor had to be raised 20mm. Easy enough to do just got to cut foam now to toddy it up a bit. Wheel was only £60 off eBay and pcd adapter £80 for two (so I’ve got one for sale

Seeing how your floor has been raised, along with looking at the pictures of the Audi spart tire/rim you've posted, make me wonder out loud if the offset of that rim is correct & safe to drive with on a Stelvio.

For comparison to your Audi rim/tire, here's a pic of my OEM A-R Spare rim/tire and a 20" A-R rim

Also, here's a YouTube video I found that shows (at the 8:20 mark) how the inflated spare should look when installed on the front axle.

Question: Have you performed a "dry run" w/ your Audi spare? Inflated, installed it, and driven with the spare on your Stelvio? Probably most important, have you tried it on the front axle?

Check it out, I'm asking all these questions because I recently had to use my A-R Spare Tire.
When I pulled out from an emergency repair area and into freeway traffic, the car handled exactly like it handled with the stock 20" tire/wheel it just replaced. If I hadn't just swapped out the tires on my own, I would have never known the difference.

I hope that all this info helps you (and anyone else reading this post) in establishing if your Audi spare tire solution is a safe alternative to the factory A-R spare tire option.

Do your adaptors compensate just for the center bore difference, or both the 5x112 to 5x110 and the bore?

if both, how thick are they?

We just 'cheat'. When we replaced the tires, I kept the best of the old ones and bought a 5th wheel. When we go on long trips I use a modified bicycle carrier mounted in the trailer hitch to carry the full sized spare. It even folds down out of the way of the rear hatch. For other time the factory donut works just fine.

Are you sure everything fits. The luggage floor doesn't look right ?

Like I said in the post I had to lift the floor 20mm, it could have been a bit less it’s just I had some wood this thickness. The wheel is actually 1/2 inch wider than a standard spare wheel. I’ll put it on the car this week to show how it fits on. Don’t forget this is an emergency tyre to get you out of trouble and like every other spacesaver there not to be run for long distance or high speed. The green line shows how much narrower it is but central to the original. The tyre is exact same size as the stelvio spare.

The adapters are hubcentric to both the Alfa and the Audi
