Perhaps 18k Kms is not all that bad. The stock Continentals on my Passat only lasted about 35k kms. I think tire wear on your T-Reg is realted to a combination of:
u must be kidding...!! 18k kilometer in the stock tires and u think its fine??? Come on!!!I had put 35k in my tires till today and they are still in good shape!!! something must be wrong.
G-Force are high performance tires with low treadwear ratings....you can't compare those to an OE all-season tire.My ES100's lasted 8K on my s2000 - does that mean the VW wear is normal? No.
