RR's for 2014......

[philstireservice]

We have a set of 2 - 255/50R16 RA-1's shaved to 5/32nds that we will let go for a very good price...let us know soon!!

I'm sure Toyo has a big say in this. You have to remember NASA is a business and Toyo throws a lot of money at it and if they want to push a newer tire for advertisement to the public then everyone has to run it.

Forgive my ignorance since I haven't researched this much, but do the RRs actually provide more mechanical grip? I thought the 100 treadwear rating on the RA1s were totally bogus, with the RR's 40 rating being closer to reality?

As far as the loss of 16" size debacle, no plans to produce the RR in 16s? Did anyone up there think to ask? At this point are we the only NASA class still running big 16s?

They are about a second faster than the ra1. Almost equal to the Hoosier R compound.

I always thought the treadwear rating use thread depth as a factor to assign its number.

So....is RR mantory? I bet if there not, some of us would be instreaded in buying slightly used RA1's and running them for a while. Heck I am in the back anyway :-)

Wait a minute, the last race I was at, you won. Or was that a Jedi trick?

They are not manditory.

Comparing treadwear on commercial tires between manufacturers is not terribly useful for performance applications since the testing done does not at all resemble what you do with the tires on the racetrack. Treadwear is used by manufacturers to position their product line more for marketing than any objective measure. The intent was to be a more reliable measurement for consumers but once manufacturers were given the control over testing it's become less than useful. Consumers are mislead on this.

the 255/50R16 will NOT be made. The 225/50R16 and the 245/45R16 will be made, but they are the last of all the new RR's to be available. We don't have a time frame, but I would guess mid to late 2014. Just a guess remember.
