Was it? I saw last week it was around 100 in Cheyenne where I lived for a few years. There's crazy-*** weather out there — I remember shoveling snow on my birthday, in May.
Hey, I was just looking at the SCDA schedule for the rest of the year, thinking about what I might do, and noticed that 5 out of the 6 days remaining at LRP are solo only. Not a bad thing but definitely unusual. I wonder why.

It was mostly in the NW corner (Yellowstone) and outside of that. It was about 5 am there when I looked. It was a bit warmer elsewhere, but still chilly. I did some camping in Yellowstone back in the day and woke up to 2” of snow on the test.....
Those are all half day events and those have aways been solo only.
No global warming in Buffalo today, right now it's 60. Nice June autumn day
Anyway, y-day at Mid-O with AutoInterests I did 5 runs (did not stay for the happy half-hour at the end as it was my b-day and my sister said she would disown me if I didn't make it back for cake ) Went out on a wet track with the lightly used and flipped RE71Rs in front and the new A052s in back with usual pressures of 34F/32R COLD. In short, after a warm-up lap I was able to drive the wet line as I usually did with the 4 'Stones, which is REAL important on that track as it's known (and rightly so) for being a real handful in the wet.
Next two runs were largely dry and I was able to feel things out a bit better....the rear of the car did feel a bit tighter/grippier as I alluded to previously but I got used to it in short order and the car seemed to balance out so I could throw it around like I normally do The 052s are quieter than the 71Rs as most of the tire scream came from in front, and when I came in I stuck my fingernail in both tires. The 052 was WAY softer than the 71R.
During lunch the skies opened up and washed whatever rubber we laid down washed away.....should mention that on the weekend a karting group ran there and the gatekeeper said they had EIGHT HUNDRED karts! I got there to sign in early and it sounded like the world's biggest swarm of bees
After lunch the track was really wet and 3 cars spun with one ending the session early; during this run the car felt really good as I was pretty acclimated to it by now and ended up passing a bunch of cars. The sun finally came out for my 5th and final run and I was at last able to air it out a bit and, apart from that bit of tightness in the rear, the car felt "normal" and I was able to post my fastest laps of the day which were close to what I normally run with the 4 like tires. The 052s did show some wear, but being in the rear it was even and not ridiculous; the 71Rs showed a lot more which is why I wanted them in front in the first place. They still have some meat left, though, and I'll start with the same setup at the Glen next week.
I must admit that I was jussssst a bit apprehensive about conducting this exercise for the first time, especially in the rain on that track, but my familiarity with the track in all conditions helped big so just got out there and got on with it. Evidently the event brass and others were happy as they awarded me their "Good Sportsmanship Award" for the event determined by the staff and corner workers ("conducts themselves professionally among other drivers and event staff.....and engages in proper etiquette"), which basically means I got the fast cars by me real quick! Nice touch, though, and a $45 discount on a future event and some other goodies to boot.
Woo Hoo.... $45 and a great day... Nice to know you are well liked...
Glad to see you mounted the tires the way you did. But by the way you set your cold pressures, your hots are really low in the rear compared to where I am at... Interesting.
I have to say, I am not surprised at your report. The stones had some heat cycles and I would expect them to be harder. But the fact you were good with the pairing either says how similar the tires are or how good of a driver you are... You pick.
Now I am interested in hearing about the A052s being in the front and rear...

I pick the tires
I didn't check the hot pressures but in the past with the Stones I'd generally see anywhere from 43-46 front (really hot days lean towards 46) and 38-40 rear. I'll try to remember to check them next time.
RE front and rear, so am I, Eddie.....gotta kill these two Stones with one Mini first

Your cold and hot pressures are definitely higher than mine. Eddie07S/VeggieVet: Your pressures are in the same neighborhood?
I aim to get all tires to 40# +/- a couple of pounds. Sometimes I actually get pretty close! This is, of course, after a cool down lap and making my way down to the paddock. Not cool for schmoes to check their pressures on pit lane coming right off the track!

Yeah, gkp, have to start them higher cold due to lack of camber. May have to adjust with the new tires as the sidewalls don't seem quite as stiff as with the Stones. I'll know better when I actually get four 052s on the car at once!

Yes, VV, not jumping out of the car right after a run with the pressure gauge I don't have with me b/c I forgot it
Anything over 38# hot on my 205/50x15 ‘Stones and they are they are like someone greased the track. At LRP, I start the left front at about 29# cold, Then right front 30 to 31#, left rear 32#, and last the right rear 34#
gkp - I think you would do well to target for 38 - 39# hot with any street tire. I don’t remember what you have now for tires or camber, so other than that, I don’t have anything better. My Falkens on my R56 with 7” wide wheels get greasy above 39# hot. On the JCW with 7.5” wide wheels I could go higher in pressure.
gbuff - at those hot pressures, I am surprised you are not “slip, sliding away”...

Oh, I am, and it's a ball of fun, especially at a low-grip track like Mid-O! Slip angle is your (my) friend......I did what you are doing with different pressures for all the tires (in my case based on rollover more than anything) but the car felt the same as when I just did XX front and XX rear so I stopped--tire wear was really no different either. Maybe with a tuned suspension you can get something out of that (as I'm sure you do) but I wouldn't know

A clarification-those are my cold/staring pressures. My target is 38# hot on all 4 tires. I have tried 37# in the rear, 38# up front, but it didn't seem to by me anything.
For WGI my starting pressures will be a bit different as a the left front is less abused in comparison to the other 3. Maybe start it at 32# and the others a bit higher, but staggered none the less. But, my target is for 38# all around...
That's closer to what I look for. 37/38. When I go to WGI in August I'll have the Falkens on and that could change everything. I my also have a bit more camber, we'll see.
I will do what I can, but with a chance of rain during both days, we may do more to just wear it off
Just checked the forecast for Monday-Thursday for both our events and Monday looks best, otherwise good chance of t-storms throughout. At least I had some wet practice at Mid-O....
Just brought a tire to Anthony Cuzzacrea at Towne Mini--he works on my car and laughs at my tires when I bring them in He'll be at your event and I think you guys are in the same run group. He normally drives a white 700+hp NISMO GT-R but that's in the shop so he's bringing his Fiesta that he wins SCCA Solo autox events with. I think it's yellow. Great guy and driver.
While I was working on Albert to get him ready for my next track event, I made a pressure bleeder that works off of tire pressure.
Tire pressure brake bleeder
The hose, spring hose clamps, valve stem chuck (which locks on with a quick release), cap and brass hose fittings are from Amazon. The regulator and quick disconnect are from HF. I want to change out the gauge from the 0-160 psi to a 0-30 to better watch what is being applied to the brake fluid reservoir and I want to put a relief valve on it that will lift at 25 psi. One nice thing about the regulator is that it is has a cutoff if there is unrestricted air flow.
The clear hose is a vinyl, that seems nice. The milky white hose is a thick wall silicone. Both are 1/4” ID, but the silicone is very stretchy and fits over the fitting on the cap that is an odd size (metric?) that is larger than 1/4” but smaller than 3/8”. I do know the silicone doesn’t like brake fluid, but I have extra and it can be trimmed if it deteriorates.

The 052s are quieter than the 71Rs as most of the tire scream came from in front, and when I came in I stuck my fingernail in both tires. The 052 was WAY softer than the 71R.
