Dave Posted January 27, 2009 Report Share Posted January 27, 2009 I've been reading a few of the threads on here and elsewhere about the Q7's tyre wear and how important it is to keep them inflated to their optimum pressure... but I have a bit of a concern... I have the 21" wheels and the tyres are 295/35 R21.. for the rears the recommended cold tyre pressure is 49psi, but on the tyre side wall it says the maximum inflation pressure is 50psi.. isn't that a bit close for comfort? :confused: Any advice would be appreciated.

Dave Posted January 27, 2009 Author Report Share Posted January 27, 2009 Hmm.. just went on the kwik-fit tyre pressure site and they reckon 36psi for front and 34psi for rears.. that's more like it! Tyres :: Tyre Pressure Search Link to comment Share on other sites More sharing options...
Dave Posted January 28, 2009 Author Report Share Posted January 28, 2009 (edited) Hmm.. more strangeness.. just got off the phone to my dealer who has confirmed that the fronts are 44psi and the rears 49psi!! Apparently due to the very low profile of the tyre and the weight of the vehicle there is a chance of fracturing the alloy at low pressures and they would take any hit on a pothole. Might give dunlop a ring for one final check. Edited January 30, 2009 by Dave Link to comment Share on other sites More sharing options...
Milo Posted January 30, 2009 Report Share Posted January 30, 2009 A bit off topic but what sort of mileage are people getting out of tyres on both 20" and 21"? And 49 psi Link to comment Share on other sites More sharing options...
Dave Posted January 30, 2009 Author Report Share Posted January 30, 2009 Apparantly, if people haven't been watching their pressures, some have been getting as low as 6000miles out of a set. When each corner costs you £350 it's a bit of a shitter.. Mine have done around 8000 miles so far, and still look ok. Link to comment Share on other sites More sharing options...
Milo Posted January 30, 2009 Report Share Posted January 30, 2009 6000 miles and £350 each Is that for the 21s? I priced up the 20s while back and I think they were around £200 each. That said, I'm only doing around 6k/year at the moment (in an A4 I should add!). Link to comment Share on other sites More sharing options...
Dave Posted January 30, 2009 Author Report Share Posted January 30, 2009 Yes, for the 21"s That's to replace the Dunlop Sport Maxx 295/35 R21 Y You can get cheaper, but they seem to have a good write up! Link to comment Share on other sites More sharing options...

corvet41 Posted January 19, 2011 Report Share Posted January 19, 2011 Bought my Q7 as an ex demo with 17,000 on the clock which had Michelins fitted. Changed the tyres immediately as they were well worn! My local tyre retailer recommended General Grabber UHPs, the tyres are 275/45/20. I noticed tyre wear on the edges of the tyres almost straight away and contacted the Audi dealer where I purchased it. They said there wasn't any known problems but offered a free 4 wheel alignment, they found all 4 wheels to be misaligned. After the problem was sorted I managed to get 30,000 miles out of the General Grabbers and have just had another set fitted. They give excellent grip in wet and icy conditions and are relatively quiet on the road. My colleague who travels with me was so impressed by them that he has just had them fitted on his Range Rover! Unfortunately you cannot get a 21 inch version of this tyre, much to the dismay of another friend who is having big problems with his Q7, he has no grip in the snow with 21 inch Pirellis and is currently having problems with the traction control light flashing when driving in a straight line on a motorway in dry conditions at 80+mph. Moral of the story is fit 20inch General Grabbers, get your alignment checked by Audi free of charge and run the tyres at 44psi all round! Link to comment Share on other sites More sharing options...
