It seems the Audi Q7 is a vehicle that has issues with tire wear. Like most heavier vehicles, it'll tend to wear tires faster than a lighter car. While we can't change this or promise any treadlife miracles, the problem can be remedied to a degree.
The Q7's Original Equipment was made available with several different sizes and brands of tires, however most of the options had one thing in common: very soft tread compounds. Typically, the tires used on the Q7 were sport truck tires or performance tires featuring relatively soft compounds and correspondingly low UTQG treadwear numbers. This type of tire combined with the weight of the vehicle usually leads to poor tire mileage. From my own personal estimate, most Q7 owners usually see about 20,000 miles before needing to replace their tires. When looking for replacement tires, I find it often makes sense to move away from the Original Equipment and take a look at more proven options with the propensity for longer life.
Pirelli Scorpion Verde
Bridgestone Dueler H/L
The following are a few of my favorite tires that come with pleasing mileage warranties from the manufacturer:
Pirelli's Scorpion Verde All Season is their eco-friendly Crossover/SUV Touring All-Season tire that combines dry and wet road handling, comfort and year-round capabilities. Ecoimpact icons on the sidewall highlight its environmental compatibility where it reduces rolling resistance and tire weight to increase fuel economy and lower the vehicle's CO2 emissions.
Continental's ExtremeContact DWS satisfies drivers' year-round driving needs by blending dry and wet road performance with light snow and slush traction. A visible "DWS" indicates the tire has sufficient tread depth for dry conditions, as well as wet roads and light snow. After the "S" wears away, the remaining "DW" indicates the tire only has sufficient tread depth for dry and most wet road conditions. And after the "W" and "S" wear away, the remaining "D" lets drivers know the tire has appropriate tread depth for dry conditions only.
The Bridgestone Dueler H/L Alenza provides elegance with an edge. Featuring Bridgestone's UNI-T technology, the tire takes behavior to a higher level by increasing comfort and control, in order to further enhance wet traction over the life of the tire. In our Tire Survey Results, the Dueler H/L Alenza receives high marks for dry traction, steering response and cornering stability. It's important to note that this tire is only available in an 18" size for your Q7.
