Ballpark range was 30-33psi. Didn't get it fully dialed in, and my exact pressure won't be relevant for you anyway. Different altitude, alignment, car weight, suspension, pavement surface, etc. will all change optimal tire pressure. If you want to optimize it for your car and situation, get a pyrometer.

I can't definitively say without doing an A-B test. My gut feeling after turning some laps on them is the same as before I tested the tire - the 245 VR-1 is going to be close to the speed potential of the 225 RivalS and 205 RE71R. Low-power cars will favor the narrower tire as well.

Has anyone compared the 245x10 vr-1 vs the 245x10 rc-1 yet? Curious to see results. Currently using RC-1 for light street use in the dry, and then at track as well. Nice to have one set of tires to do it all, but maybe the step back to VR-1 the next time around will have some merits. It would be nice to have ability to do track days in the wet also, but I don't know how a 300whp+ miata would fare then with any tire

80% chance of rain at Saturday's autocross. Big parking lot, should get a good assortment of turns so you can get an idea of how they grip. I have a GoPro I can suction-cup to the car assuming the latch replacement works I might get some wet video up. I was going to register for Sunday too but 70% chance for rain there too, gonna pass on that. Not looking forward to two days in the wet. :-/

Finally got my tires mounted and put them on for some pictures. I expect to add spacers up front to try and retain my steering angle. Flares are almost certain, how ever they fit better than expected off the bat.
Car has flat roll with no pull, -2.5 degrees up front and -.5 degree rear. Ride height around 4.5 at the pinch weld.

My GRM tire test issue came today.
Vr1 245 vs Rival-S 225.
Boils down to what we thought, rival-S still faster, but vr1 might last longer.
Because of its extra depth, the vr1 squirmed enough to overheat before the rival-S. That's interesting.
Re71 still king of 205/50s

Was bit disappointed but I guess it was expected.
According to this issue, Rival-S has updated thread design for 2016. (Inner block change)
And they are even faster than last year's Rival-S.

Multiple tests, first the 225/9" Rival-S's vs 245 VR1 on both 9" and 10"
Then all four in 205/50.
If you want all the data, buy the issue. Andy does too much for us as is.

No need to condensed; I has subscription, plus my employer has been a paid advertiser in every issue for a decade. I've had a couple of my cars in GRM for various things, I've been used/featured/quoted in articles, and a company car was on the cover a few months back. I haven't seen this magazine yet.
