What drivers say about their 275/30 R21 tyres
The most recent owner reviews fitted in this size, in their own words.
I saw another review on these tyres by an Audi S6 owner and couldn't agree more. On a less powerful lighter car these tyres might be fine but they are useless on an S7. I also have changed to Michelin PS4 for a more conformable ride and better wear with far more stickability especially in the wet. These are expensive overpriced tyres.
Note car ios S7 but the tick down box only offers S6 then S8.
Had these on my Audi S7. Very average tyres. No grip in the wet. Sideways slides in the dry through fast corners. The Audi is 4wd so this helps the tyres but not enough to overcome the weakness in these tyres. They may offer better grip in lighter less powerful cars but pretty useless in heavier high performance cars. Very poor wear. Have moved to Michelin PS4s. Hopefully these perform far better.
I drive a Audi A7 Quattro. These tyres are good when new but are lasting not even a year and around 5000 miles. Have so far replaced 7 tyres due to inner side wall splits. These are the most dangerous tyres I have ever purchased. The splits show no sign of coming they just happen when driving. The car is totally standard. They are now being replaced with Continentals.
Had two sets of these. Wear is fast especially with camber of S7. Terrible in the wet when braking and entering corners under hard braking. Wouldn't buy again. very hyped up tyre. About to try Michelin Power Sport 4s
