Hi..Just got above car which has 19 inch wheels on it. Wanted to go down to say 17 inch and add winter tyres.

 

A) Can i go down to this size and if so what do i need to look out for re wheel width, offset etc?

B) Or do i stick to 19 inch and buy winter tyres?

 

Any help most welcome. ta

Try this website to figure out what wheels and tyres will fit.

Try your drivers door label for tyre and wheel sizes. You will need to keep them same offset.

Thanks for the advice guys, much appreciated :)

There’s another useful site I found.:

Tire size.com to compare different tyre & wheel sizes.

However, there is a better site, I’ve lost the link but it had vehicle details in too, so it could check which offsets fitted, bodywork/suspension & brake callipers clearances too.

Try a google search, although I suspect 17” wheels may fit that M.Y. Brake callipers & discs being the big issue.

(I think it was only the 1998-2005 models that used 17” & 18” wheels.). Not certain though.

if you can’t fit smaller alloys, some winter tyre suppliers can also provide a set of steel wheels, which may be an option & they may know if you can fit 17” wheels.

Looking for something else I spotted these, which may answer the question!

This is what google says about it.

Yes, wheels from a 2011 Audi A6 Allroad (C6/C7 generation) are generally compatible with a standard 2011 Audi A6

. Both vehicles share the same 5x112 bolt pattern, a 66.5 or 66.6 mm center bore, and similar wheel offsets. 

However, there are important factors to consider regarding tire size and overall fitment:

• Bolt Pattern & Hub: Both cars use a 5x112 bolt pattern and a 66.5mm (or 66.6mm) center bore, ensuring they will physically bolt onto the hub.

• Allroad vs. Sedan/Avant Specs: The Allroad often uses a slightly different offset to accommodate its wider stance, and it typically runs a taller tire profile (e.g., 225/55R17 or 245/45R18) than a standard sedan.

• Tire Size Differences: While the rims fit, the tires on the Allroad might be wider or taller than what is recommended for a standard A6, which could lead to speedometer inaccuracies or rubbing if the car is lowered.

• Suspension Clearance: If you are using the Allroad wheels and the original Allroad tires, the tires may look too "meaty" or tall on a standard A6. 

Conclusion: The rims will fit perfectly, but you may need to swap to standard A6 tire sizes for optimal performance and appearance on a non-Allroad model.
