Have a 2019 E-Tron which I love, but the stock rims I’m not so excited about. Is it a bad idea to put Q8 22” rims on the E-tron. Have seen a few people put 22” on their E-Tron but not sure if it will change range of distance for car. Any input would be appreciated.

This will definitely decrease the range as your car will have heavier rims to rotate
There’re plenty of posts here noticing range being less for 21” rims vs 19” rims, for instance

Thanks! Is it a drastic decrease. I could t find how much decrease In distance. Thanks for quick response though.

I'd say maybe 5%
Considering that the range is already on the lower side, it would have been a problem for me
I actually like their 20" tires with 5 spokes a lot more than either 19" or 21" (prestige) ones and getting a good range with them

There is so little rubber on the wheel with a 22". I would vastly prefer the smaller tires for efficiency and light off-roading. Not to mention killer potholes..

Agreed.
Sound insulation is going to suffer as well from less rubber, IMHO

IMPORTANT: Please keep in mind that for EVs they frequently use special tires with foam barriers to deaden the sound and also support heavier car.

So for unsupported rim you might not fins the right tire.

I recently did 22x9.5 Q8 reps on my etron. Surprisingly, they were actually lighter than the factory 20s and just as quiet

New wheels are rated at 900kg and wrapped in Continental extremecontact dws plus, 265/40/R22.
Range appears to be unchanged but I’ll need to get more drive time to confidently report on it.

I love how the wheels look on the car, really sporty looking and meaty. I would be worried about the low profile tires though, depending on where you live and the roads you travel on. The 22‘s just fit the car so well! Too bad the etron wasn’t tuned to be sporty, we will just have to wait for the S version.

Love the wheel set up looks really clean.

Where did you get them from?

Thanks,

Been looking into this as well. New wheels can be tricky. Besides the already mentioned weight of each wheel, you also have total diameter to look at. Many times, when going up a wheel size, you come down a tire size (-1) to the total combined diameter stays the same. Which reduces the sidewall thickness and can lead to more tire blowouts and rim damage.

There is also the issue of the sound deadening in the tires as others have mentioned.

However the biggest surprise to me has been the fact that wheels are rated to the weight of the car. Many times, after market wheels are not designed to handle the extra weight of electric cars and this needs to be looked into when trying to purchase larger wheels.

So basically, you need a wheel/tire combo that is as light as factory, has the overall same rolling resistance/diameter, and is rated for the weight of your car.

What I have done on my previous electric cars is keep the larger wheel for summer driving and get a smaller rim with winter tires for colder driving. I try and recoup some of the lost range in the winter with smaller rims.

Does anyone know if the eTron will detect the change in rims and allow you to reset the system to accomodate? My current vehicle (Tesla S) detects the change in wheels and asks you which rim size is on the car now.

Looks amazing! Is the car still running well and any problems with clearances or sensors with the car?

NO issues whatsoever nor adverse affects to the vehicles funtionality. I've since sold it (back in Sept.).

Has anyone else fitted 22’’ wheels onto the Q4 ETRON? I am really tempted but I am just worried about possible problems with the car. I’ve just picked up my Q4 ETRON which has 20” alloys however the 22’s would just set it off.

I see 22x9.5 Q8 reps have been fitted with 265/40/R22 tyres. Do the wheels/tyres need to be staggered?

Hi there,

Could you tell me where you purchased these rims from and how they are holding up? Also, is the offset and such the same for Q8 vs eTron?

Q8 offset is 20mm and rim width is actually 10 inches. A 22" wheel for the e-Tron would do better in a 9.5 at 26mm offset. It was also mentioned that he sold the car in August last year.

I believe he has purchased them on eBay as they were replicas. The link is old and dead. The ones on eBay now are the same specs 22" by 9.5 inches and a 26mm offset, same as above. I have asked many vendors if they can confirm the weight rating on the wheels, nobody seems to know. In cases like those, one company makes the wheels and many vendors sell it. One can assume they are the same spec, but I want to be sure. It was stated above the wheels were rated at 900kg, which is a bit over 2000lbs. 1900lbs or above are needed for the e-Tron so if these ones for sale are the same, they will be good.

However, the problem is the tire choice at 265/40/22 as those Conti's are only rated at 106 load index, the e-Tron requires a minimum of 108. But changing the tire to a 275/40/22 increases the over diameter by less than 1%, but those tires are 108 load index. The Continental ExtremeContact DW06+ is a fantastic tire. They make it in the 275/40/22 for the same price.
