Has anyone tried 16" wheels on their A3 e-tron?

Hi everyone!

My A3e came with the premium 18" wheels which I find to be way too big for a car this size. The area in which I live has lots of very dangerous potholes and poorly maintained roads in general, so the ride is rough!

Has anyone tried downsizing from an 18" to a 17" or even a 16" wheel for the A3e? I tend to downsize my wheels for better road compliance on all my cars so I'm sure the results will be pleasant, but am wondering what others have done that they are happy with.

Cheers.
 
I believe the base model came with 17 inch wheels - that is an easy downsize. The 18 inchers where part of the Sport Package and Premier model. So 17s from any A3 MY 2016 17 18 should have same offset and clear the Calipers. Audi Wheels from earlier wheels A3 or A4 likely would fit but need to confirm offset. Going to a 16 inch wheel would need advice from someone more aware of the fit. A dealer or quality Wheel &Tire shop. Wheel for a MQB platform VW MY 2016 17 18 should fit. I plan to fit 17s from old 2014 VW Jetta TDI with Snows for winter.
 
17" wheels is a good compromise of ride and handling. However, I did get a blowout on the freeway from a large pothole. Don't know if a 16" would have survived it either.

My 2016 A3e came with 17" wheels (ContiProContact - 225/45 R 17 / 91H ). I can't comment as to how they compare to 18" wheels, but I can at least confirm availability of the 17" for this car. And as Jacks replied, probably any A3 wheel from 2016-2018 should fit the A3e.

PS: I noted another post expressing concern about the factory ContiPro breaking traction when attempting to accelerate quickly off the line. Mine does this as I'm sure they all do. I'm guessing that in order to maximize economy, a low-rolling resistance tire is used, which can't quite handle the off the line low end torque from the electric motor. I mention this because if your 18" does this, the 17" won't be any better, at least with the Contis.

Our 2017 A3 Sportback e-tron Premium Plus came with 225/45 ZR17 standard. We are happy with this size, though a 50 R16 might have been nicer for pothole comfort.
 
I've run 16" wheels on our A3 e-tron (2016), which came with 225-40-18 tires, which lasted maybe 40K km before blowing a belt.

Have used both stock-diameter 205-55-16 (common on the VW Mk7 Golf - same MQB car, basically) and slightly taller 205-60-16. Both ran fine. I'm far more about comfort than performance these days, so these smaller rimmed wheel/tire combos were very nice. Currently on 225-50-17 (10% more sidewall and 3% greater circumference than stock 225-45-17 so the speedometer actually reads accurately) Michelin CrossClimate2 and I'm at least equally pleased with those.
 
I have a set of 16s with michelin X ice winter tires. I much prefer the 18s and will upgrade to higher performance tires when they wear out (michelin pilot all season 4 or conti extreme contact).. yea yea there is a small increase in EV range but I'm not hung up about that. The car has a ICE and I'm happy to run it especially in the winter.

Thanks for sharing your experience with the 17" wheels @bruuster ! I'll take what I can get, if 16s fit, I'll go that small for the protection/comfort.

Hey @Jacks A3 ET , you're right, I was able to find the following information about the OEM 17" wheels that Audi offered on this car:

17" A3 e-tron turbines
17x7.5, et 51, bolt pattern 5x112, 26.5lbs
Part#: 8V0 601 025 CD

Hey @Nuje that's very good news to my ears. Thanks for confirming that you've found that 16" does indeed fit over the front brake calipers. Of the two different tire sizes, did you prefer the 205/55 or the 205/60? Any issues with rubbing at full lock in parking lots and such?

Would you say your ride quality of equal to or slightly worse than 16s now that you are on 17s?

I'm all about comfort these days as well, although one could argue that smaller wheels and more tire increases performance in rough terrain. The road conditions have gotten so bad here, I have to slow down to unsafe speeds to avoid busting my tires/wheels up. I think one of the main problems is how heavy these wheels are, so when they hit something, they send so much force up the suspension into the cabin...

Do you have pictures of your A3e running 16s? Any shares would be appreciated.

@cmc , oh very nice! would you please share some pictures of the 16s on your A3e if you have some handy? Thanks for sharing your experience with us.
 
Hi there sorry no pictures of the A3 with winter rims.. They are Sparcos. Will not be mounting them again until perhaps November. I also have a Mk 7 GTI with the same 18s and same factory Contis. Due to the lower weight the GTI is considerably more sporty and fun in the curves, thus my goal is to improve the handling of the A3 with stickier tires, not go in the other direction.
 
... Due to the lower weight the GTI is considerably more sporty and fun in the curves, ...
The "Base Weight" of the Etron is 3,600+ pounds. I don't know what the load index is/was for the factory tires, but absent knowing that, I'd make sure any new tires are at least a Load index of 84 (1102 lb, 500kg), or maybe even 86 (1168, 530). Also, make sure any aftermarket or GTi takeoff rims are up to the weight of the Etron.

My camping buddy had a one-ton truck rim fail (single fracture straight in from the bead). The aftermarket rim was rated at only 3,500lb at 60 psi. He was of necessity running load index 129 (4,000+ lb) rated tires at 80 psi and had no idea his rims were the weak link. I run the same 34x18 inch tires with 4,500 lb rated rims. I spent last summer in the rig in Alaska and wondered how any of these short sidewall 18-20 inch sedan rims survive up there. I guess they don't.
 
I hear you. Our 2018 A3 e-tron came with the 18” inch wheels and Conti Pro Contacts. I was concerned about pot holes too. But, when it came time to replace the tires, I switched to Conti Pure Contacts. They greatly improved the ride. I recently bought a TTRS that came with 20” wheels. Really put the 18” wheels into perspective. 20” is ridiculous. I’m getting 18” wheels for the TTRS. Can’t go smaller because of caliper clearance. If you can find 16” wheels that clear the calipers, should be fine. Just make sure you get a tire profile that minimizes speedo error. Use “willtheyfit.com”
 
Keep in mind, too, that a tire that is ~3% larger circumference (like the 225-50-17 instead of stock 225-45-17) will actually make your speedometer read accurately. Cars come from the factory like that so there's a comfortable cushion to keep people from going back on the manufacturer and saying "hey - I got a speeding ticket even though my car said was going the speed limit" (or so the internet surmises).:)

The flip side is that odometer DOES read / record accurately with stock tire sizes. So, if you're seeing accurate speed from the speedo, you're odometer is missing roughly 30km every 1000km.
