BFG R1-S Test and Tune
So 3rd event was this weekend. Again at Mineral Wells. This was a quasi-pro solo / Mirror Cross. No x-mas tree. But two identical courses with a drag race start.
We ran in the middle of the day. Run group B, with the format A,B, Lunch Break, B, A
One run on each side and then co-driver swap in the AM. In the PM we ran traditional pro-style. All your runs at once. Left right, left right. Co-driver runs and then one more session like that. So 12 runs total. Hopefully that made sense LOL
Times are below
Jeremy Foley
Left 23.531 / 23.674 /22.813 /22.907+1 /22.768 /22.399
Right 23.895+2 /22.834 /23.000 /22.936+1 /22.862 /23.032+1
Blatone Payne
Left 25.173+1 /24.038 /23.833 /23.453 /23.415 /23.103
Right 24.400 /23.498 /23.875 /23.598 /23.956 /23.278+1
It was cold in the am. Probably high 50's and windy by the time we ran. It took several runs to get real heat in the tires. We tried 40psi all the way around for our 1st of 3 runs. On my 2nd run and 4th total dropped back to 38 and the car was happy again. Dropped some big time on my 4th run to the 22.8xx.
Lunch break and it got hot almost instantly. Went from jackets to shorts in an hour. I think it was right around 80 +/-
So with a small group we jumped into doing runs back to back, with no sprayer. Tires held up amazingly. Both in wear and heat resistance. Everyone was commenting on how we were NOT spraying. Ultimately, my fastest run was the last of the day. Part of that was a trick in the course. But I never felt any drop off in the tires. I did notice there was a slight push on my last runs. This was the best the car ever felt too.
College Station Tour is this weekend! Sticky concrete on a HUGE site!

Marshall, this was probably the coldest autocross I have done in 9 years. Temps were in the high 30's. WITH a constant 20-30mph breeze. Our rear tires NEVER got warm. Lots of grip in the front and no grip in the rear =
holy crap, high 30's! i woulda thrown the rain tires on! HAHA
tires were beyond useless on that surface. didn't help the course was biased pretty heavily towards light nimble cars. Lateral grip was down more than 20% compared to what they do on the other two surfaces we've run them on. probably would have done better on rivals...
we're going to stick with SM for the pro's this year. still TBD for nats.

Not sure if you guys are seeing this, but right now on Tirerack the 265 18 S's are going for $193........
So whats the word on these? I mean for that cheap it's worth testing.

Well we will be at spring nats/pro. I've been talking with Tom, and we may jump into SM for the pro to compete head-to-head with you guys. So let me know!
I'll see if I can convince my co-driver to pick up a set so we can test on them. I haven't read the specs but I would guess they may be too short compared to the 285. I'm sure they will still be plenty wide LOL
