Nissan 370 GT SKYLINE CROSSOVER Tyres

I purchased my 2009 Nissan Skyline 370 GT CROSSOVER a rear wheel drive car with 335 horsepower, with the Goform Zonda GH 18's already on them. Being a direct Japanese import, I'm not too sure how long the tyres had been on the vehicle before I purchased it ( Only had 27,000 kms on the speedo). I have had the car for 9 mths now and the tyres are OK on dry road conditions, they are quiet and comfortable, but wet weather driving is a different matter altogether. The tyres just let go without any warning at all and I have had the front and back slide out on me going around roundabouts in the wet. Even taking off from the traffic lights in the wet, you cannot give them too much gas as you will spin and just sit there. I would not recommend these tyres at all for a performance car. Good luck.
