The latest Evo, issue 110, just arrived through my door and the tyre test makes interesting reading. Tested 225/45 R17's on VW Golf GTi. Here's the results:
1st: Godyear Eagle F1 asymmetric
2nd: Vredestein Ultrac Sessanta
3rd: Continental Contisport Contact 3
4th: Bridgestone Potenza RE050-A
5th: Michelin Pilot Sport PS2
6th: Pirelli P Zero Nero
7th: Kumho Ectsa STP KU31
8th: Dunlop Sport Maxx
9th: Yokohama S.Drive
All the tyres seemed to exell in one area or another with the exception of the Yokohama's that were bad at everything: straight line braking in the wet took 12meters longer than the best tyre, the Goodyear.
Some interesting facts:
1. Is bigger better:
On the Bovingdon wet handling test circuit, lap time about 60secs on the 225/45 R17 Bridgestone, for comparison the larger 18" wheels with slightly lower profile 225/40's were timed at 2.5secs slower....so lower profile in the wet means slower speed.
2. Fresher the better
Brand new tyres stopped in the wet 7 meters (14%) shorter than 6-month old tyres (both unused). So storing tyres is like storing elastic bands, not good. Due to rubber degredation. Date code is on the side of the tyre, I'm sure most people know.
Lots more in the article.
Hope this is interesting, and that you haven't just bought Yokohoma's,
