No, that's a forum post. Andy Hollis did tire testing articles, IIRC, two months in a row. The first one briefly mention the Rivals and the second went into more depth. I'm thinking it was 8 or 9 months ago. I'd have to dig through my 'paper' magazines to find them. The guy who helped him with the testing AutoXs and runs NASA TTE locally. He suggested 25 cold for my 225s on 9s.
32 psi was the happy place on the skidpad. I am assuming that's starting pressure. They did three laps so they're not going to heat up much (I think). Says not much change in skid pad times at lower or higher pressures. And consistent performance across different tire temps.
This all makes me even more eager to get them on track. M@MRLS will be the first time tracking these. I think I will start at 27 cold. It just doesn't get very hot in Monterey in September - usually.

Not saying that exactly these will fit your needs perfectly (adapter to your favorite tire inflator etc). But the prices ($300) will give you a hint.
Small bottles are easy to carry, dead silent and fast (compare that to any small compressor).

WARNING, never use a nitrogen tank without a regulator to fill a tire. That is one sure fire way to kill yourself.
I read an article with back to back track testing the NT01 Vs the Maxxis RC1. The difference was .17 seconds. The tester felt that the Maxxis was easier to drive.

Anyone have experience using Kumho Ecsta's? I got an offer from some guy at the track for 4 new tires for $400 and he's local so I can pick them up and save on shipping/tax etc.
Worth it, or should I just go for something more known like Toyo RRs or find some SM takeoffs?

Ecsta LX Platinum
Ecsta PA31
Ecsta ASX
Ecsta 4X
Ecsta SPT XRP
Ecsta SPT
Ecsta LE Sport
Ecsta XS
Ecsta V700
Ecsta V710
Farther down the list you go, the better off you'd be.

So is it the new "S" carcass? ie S75/S80/S100
If so I will give me a try. The R80's are great but even those are a bit dicey out of the gate. The R100's are hell on a track that is not very hot. The 75's would be great if they came on strong out of the gate and lasted 20 mins.
