Are you sure about that HOT tire pressure?
Since I have been on the RR tires all season & also ran them on the TFB car during the 25hrs, I can openly share the following:
- Cost is about the same as shaved RA1’s (more expensive if you weren’t accustomed to shaving)
- Very fast new, very fast should you scrub first then qualify.
- Your quickest lap times can still be found between 8-12 heat cycles.
- They are confidence inspiring…Just drive them harder.
- They are consistent & predictable throughout a race.
- I did chord 1 tire of a matching set after 15 heat cycles.
For many, spend more time figuring out this tire & drive to the tire.
Hope to see all of you at Miller.[/quote]
Yes, Im sure. I will say this though. Tire pressure should be set with a tire pyrometer…always.
Here is some basic tire info.
The more (higher) pressure you can handle (drive fast and competitive) the quicker you will be on the track. Higher pressure results in less rolling resistance. Don’t confuse less rolling resistance with less grip. With a R comp tire actually, if you need grip you ADD air, not take it away. Basically if the car is not loose, not lose control loose but it rotates nicely loose, you are not going fast enough.
