Deeper tread runs hotter, right? That might have something to do with it, too.

To back up my previous post, here are pictures of mine after 28 runs. 295/35-18, 10.5" wheel, 3150lb car.
These are the 6/32nds version so just over 1/32nds wear. 28 runs, 200ish highway miles, 90 degree weather.
Looks like it's reading 4/32nds so you lost 2/32" of tread.

Probably right, still doesn't back up the OP's claim
In reply to Patientzero :
There were multiple cars at Nationals with the same issue. My claim is fully backed up. Your single point of anecdotal evidence on a different tire does not disprove it.
This just in: Cars that are hard on tires are still hard on tires.

These are the spec tire in World Time Attack. If this was a widespread issue I think we would of heard about it by now.
I don't think the same compound with .030" more tread depth is a "different tire". There is absolutely no way to tell them apart.
Having one defective tire out of even just hundreds is actually a pretty good ratio from what i can tell. There are tons and tons of brand new tires that would never make it out of the factory just for geometry and road force issues if companies didn't know that the majority of customers don't have enough context to pick up on 'minor' flaws and articulate a meaningful case against a manufacturer that didn't just cost them... another crapshoot tire or four. And that's if they get past the retailer! I'm sure some manufacturers stand head and shoulders above the rest. Maybe their ratio of E36 M3 tires is 1:500 or even higher, but my experience diagnosing used tires and installing new ones suggests that your likelihood of ending up with a product that's defective in some way shape or form is WAAAAY higher with tires then it is with a lot of other things. And heck, if it had an all-season or otherwise non-racing-related branding you could sell a tire like the failed one pictured above to thousands of people until you ran into one who was going to get it hot and loaded enough to uncover that particular flaw.

Heh heh heh... you said "tires"
More anecdotes that don't add up to data: I have a friend who had a brand new Michelin (BF Goodrich in name) rally tire delaminate on a short road section between the RXNC and his hotel. These are the same tires in model and size that the WRC were using, they are expected to do hundreds of road kms on transits as well as up to 180-200km/h on gravel stages, so 50mph on a 2 mile highway drive back to the hotel from the balloon field should have been nothing.
Weird things happen sometimes

Your claim is also based on anecdotal evidence. We don't know who you talked to.
All my evidence is also anecdotal coming from me. Even if my team got the info from probably the most reliable/scientific source in autox.
They're soft tires, we're not debating that.
People push cars hard when the clock is running. I had seen very aggressive wear levels, on another street class car that went on to finish 2nd this year, in the month leading up to nationals. I used to be way more punishing on tires than I am today. Mazduece and I worked on it leading into OLOA because i was scrubbing hard in turns and bleeding speed and turning soft tires into dust more quickly than I needed to. And knowing the car those are on. I am very suspect the front end of the car was overdriven.
Yoko also 2/32 lower to start than the other 200tw tires(as we know) and have even less shoulder so they should look lower from the beginning.
The thing that really matters for those at the front is competitive life, not total life. I was talking with a Texas native multi time national champ about them and he pointed that out to me. People who are chasing the last few tenths on the big stage may not see a difference compared to the local "regional only" type guy because the Serious business racers are probably buying newer tires more quickly anyway to maintain their competitiveness.
If you're not competing at the very pointy end of the field. Then don't run the Yokos if they don't work/ make sense for you. There are multiple classes where they just don't seem to be "the tire" thanks to size restrictions and driving styles.
We ran them on the STH Audi because they seemed to put power down better and have similar lateral grip to the BFG's when my teammate ran the car during the Pro Finale. And those claims seemed to be backed up for me and my driving style matched them well in the car.
They appear to be in the noise for most classes.
I liked them, but I'm not going to recommend just anyone buy them. I'd recommend someone running regional autox run a RE71 or BFG with more tread and longer overall life. Because the deeper tread and lower prices for those tires should be beneficial.
