Well, I'm the proud owner of a set of brand spankin' new 275 40R17 g-Force R1s,
and I gots a few questions:

1) I used to run ~35 PSI in my old-model 245 R17 R1s, so a reasonable starting
pressure is about, what, 45 PSI for the g-Force?

2) Do the g-Forces react to air pressure changes the same way as the old R1, ie,
backwards to every other tire on the planet? (Increase pressure to lessen grip,
decrease pressure to increase grip)

3) Is it just me, or is there way less rubber on this tire? When I look at the
inspection holes on my well used, shaved old R1s, it seems like the hole is
deeper than on my new, unshaved g-forces - although this may be an optical
illusion, as the inspection hole on the gF is much bigger than on the OR1, and
it's got that funny step in it.

For the money I spent on these tires, they'd better last longer than one
event....

4) What are we supposed to use as a rain tire? Those grooves (except the 2
center ones) look like they'll last maybe 2 runs on concrete, and I don't think
grooving irons are allowed on SP tires. What do the World Challenge guys use for
rains?

5) Did anyone find they had to change shock settings when they moved from the
OR1 to the gF? Harder or softer in bump, rebound, or both?
