I used my first set of GY F1 tires up in 12000 miles. These tires are expensive and 12000 miles is just too short of a life span.

Since I was installing a set of custom 19" Forgeline wheels, I got a good buy on a set of Toyo T1R's (with a set a wheels but that's another story).

It is amazing the difference a set of tires can make. Where the F1's were:

• Extremely Responsive
• Very Predictable
• Not to be Trusted in the Rain (forget snow)

The T1R's are:

• Substantially slower in response
• Not Predictable
• Softer in ride
• Great in the rain (I never drive in the rain, unless the weather man lied)

Consider this, my T1R's have a shorter side wall (because of my 19" wheels), and are wider. The T1R wallow, where the F1 will not. I made some quick transistion with the T1R's and my stablity control engaged...it never did that with the F1's

The jist is, stay with any of the run flats. The stiffer side walls give a lot better feel when you press the car. If you need a soft ride or you drive in the rain or snow go with something like the GY RS-A runflat.
