Back on topic, Mr VXL, if you are struggling with RTs (an dthe current crop aren't as good as 2 or 3 years back), I think you will be hugely disappointed in GY F1 Assym2 - I know I was.
Both sets were definitely in the "midrange" (ie, Nexen, Kumho) levels of grip, both laterally and under braking/acceleration.
Just goes to show how one person can be pleased and another disappointed with the same tyre on the same car, and I don't exactly hang about.
Only tyres I've had on this Omega are Michelin Pilot Sports, which it came fitted with from new, replacement Pilot Sports x 2 sets, Hankook Ventus Sport, Toyo T1R's and the Goodyears. I suffered an instant deflation blow-out with one of the Hankooks so was reluctant to go that route again, the Toyo's were ok but were grippy due to soft rubber and wore down quite quick. The Goodyears have always stopped me when needed so I stuck with them.
I have noticed that they crack between just one of the tread lines early in their life though, which worries me, having already suffered with the Hankook.
As my fronts are due I'm interested in what other brands will stop with confidence, price not an issue.
Zoom in and you will see the crack. This appears on all four tyres in the same place.
