Go with 275/45R20 Tires on 20" Wheels for Your Audi Q7

Friday, April 12, 2013 by Cy Chowattukunnel

An Audi Q7 with Audi's quattro® all-wheel drive should have zero problems in the snow, right? Not if your Q7 came with 21" Original Equipment wheels and 295/35R21 summer tires. Unfortunately, none of the major tire manufacturers make an all-season in this size and there's not a good alternative 21" tire.

If you live in an area outside the Snowbelt, you may not need a set of dedicated winter / snow tires. However, the summer tires currently on your vehicle aren't going to be much help once the temperature begins to drop. The solution? Downsize to 275/45ZR20 Continental ExtremeContact DWS tires on 20" Andros Spec P wheels.

The ExtremeContact DWS features Tuned Performance Indicators -- visible letters molded into the second rib from the outboard shoulder to alert drivers of their tire's performance levels. A visible "DWS" indicates the tire has sufficient tread depth for dry conditions, as well as wet roads and light snow. After the "S" has worn away, the remaining "DW" indicates the tire has sufficient tread depth for dry and wet roads only. After the "W" and "S" have worn away, the remaining "D" indicates the tire has proper tread depth for dry conditions only.

275/45R20 has the same overall diameter as the 295/35R21 and is 1/2" narrower. The 275/45R20 is an Original Equipment size that Audi uses on certain Q7 trim levels and is compatible. Since your Q7 uses the Indirect ABS-based TPMS system, there are no direct TPMS sensors to purchase. We'll include our free mount and balance, therefore your Tire & Wheel Package ($1156* plus shipping) will arrive ready to install.
