Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 235/60R18 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 215/60R19; one rim size up, 0.19% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 255/45R20; two rim sizes up, -0.23% OD change. Noticeable ride penalty, higher pothole risk, meaningful tire-cost premium.
Use the plus-size calculator to evaluate any rim step against the OEM size.
How to choose tires for the 2005 audi Q7
The 2005 Audi Q7 ships from the factory on 235/60R18 tires mounted on 7.5x18 wheels, with a load index of 107 and a speed rating of H. 6 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the Audi Q7 comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number, in this case 107), speed rating (must match or exceed the placard, here H), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.
For 2005 Audi Q7 owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.
Before purchasing, verify the tire size on the driver-door placard of your specific 2005 Audi Q7, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

TWO BLOW OUTS 2 MONTHS APART ON SET OF TIRES. NORMAL HIGHWAY DRIVING. FIRST ONE WAS RIGHT FRONT TIRE WHILE TRAVELING ON FREEWAY - THE SECOND BLOW OUT WAS RIGHT REAR TIRE WHILE TRAVELING ON HIGHWAY. ALL TIRES WERE PURCHASED NEW ON JUNE 9TH 2014.
Noticed front Goodyear Eagle Sport 285/45R20 tread are cracking and peeling. This is my second set of at the same OEM tire having the same phenomenon as original tires that came with vehicle when purchase new. Per dealership, this is a known issue with Goodyear tires and was recommended to switch to Pirelli tires. Current tires are still under manufacture warranty but if a known issue, why is Goodyear still selling tire exists? This failure seems to occur after about 15k to 18k miles of usage. Concern tread will tear apart at high speed and could cause an accident on there road.
285/40R21 I was pulling out of a parking lot onto Rt 40, a secondary, 2-lane road, at approximately 6pm. As I accelerated to approximately 30 mph, without warning I heard a loud noise and felt the pull of the right front tire. I pulled off into a gas station parking area that was nearby and was very fortunate to have avoided an accident due to the significant traffic at the time. Upon inspection, the tire had a complete and catastrophic failure of the sidewall, stranding me at that location until Audi roadside assistance transported the vehicle to our local dealer approximately an hour later.
The contact owns a 2014 Audi Q7 equipped with Nexen HP, Tire Line: Roadian, Tire Size: 275/45/R20, DOT Number: 8YEHDECR2122. The contact stated that after washing her vehicle she noticed that a bubble had formed on the side wall of the passenger's side front tire. The contact stated that the front tires were constantly losing air. The contact stated that this was the fourth set of tires that had a failure from the same retailer. The contact had originally purchased the first set of tires over one year ago, and all the tires had experienced the failures. The manufacturer was not notified of the failure. The approximate vehicle failure mileage was 120,000. The tire failure mileage was approximately 1,200.
