So much for my reading comprehension.

He did not have any problem when running the same tire as you.



I will try to gracefully bow out now . . .

Please don’t! You’re making a lot of good points and have me thinking.

One thing seems clear, my toe out is doing nothing good for this problem right? Clearly I need to set it to zero.

@dave2278 is running the SC3, different tire. I’ve run that tire without this delamination problem.

stevebd, had I read more slowly and carefully, I would have noticed this before now. My apologies for wasting your time reading my posts. I have deleted all of my posts above, and I will try to be far more careful in the future.

You shouldn’t delete anything. You’re on the right track and I think it’s a clue that I’ve run the SC3 in this same exact manner without problems but the 3R is delaminating on me.

I think you're on the right path all things considered.
A cold tire is definitely not as flexible are tearing makes sense to me. A soft tire that is not flexible I think is likely your problem.

Reading your entire thread. You mentioned a 4 point harness and the Boss seats. I don’t see a harness bar. How are you mounting the shoulder straps?

I use the Scroth 4 point ASM harness. One of the shoulder straps clips into the rear seat belt receptacle on the inside of the rear seat, the other clips into a receptacle that you install on the outside of the rear seat.

For some reason,I'm just now seeing this. What you are looking at on the outside edge is the tire rolling over. That little gap is where the tread " band" is bonded to the carcass. Depending on who builds the tire, it is more prominent. The normal way to get around this with a band aid is to add more psi. This is one reason IMSA makes us run a minimum tire pressure at race start. The better fix is usually to add camber, check the toe and maybe add a little pressure. Take one of those butane torches with you, and a paint scraper so you can clean off a band of rubber at the wear indicators, that way you get a better defined idea of what's going on without the crap getting into the middle of it.

I feel like the outer wear is normal but the delam is not?

How much use on the tire? What pressures cold/hot

How much use on the tire? What pressures cold/hot

12 heat cycles, 700 miles, track only, 34-35 psi hot. I usually start at about 28 cold and bleed down to 34-35 hot.
