Which Toyo Proxes are we talking about. PX4's I found to be awful, T1 Sport ok but the T1R I love to bits and is far better than the Continental Sport Contacts I was using. Been running them on my A4 for about 3 years now and have just put another pair on it today. They do seem to be getting thin on the ground now though

Never used the Eagle F1 but for every good story I hear there seems to be a bad one. Couple of friends have had issues with them which I was surprised at but one could very well have been down to driver neglect rather than a fault with the tyre
