Chris thanks for jumping in here.
42 cold.
Camber is max front at -1.5 and -1.8 rear. S/A Koni's, usual BS setup.
Normal AX times between runs except for 4 runs on a test/tune course with about 3-4 minutes between runs. It was 42 degrees out and the tire temp's didn't even get warm to the touch.
Cord was on the outside edge.
Not on the same side of the car. And they were rotated front to rear between events. It was the rear's that corded when they went away.
Car is an '07 with 10,700 miles. It's like a new RX8, no issues anywhere.
I've run Hoosiers for 17+ years and never had them cord in 21 runs.
Previous car was a tire eating BSP EVO with 285's. I'd get 50+ runs on it and I never flipped the tires but should have.
No pictures because I was unhappy and just tossed them and bought 710's.
I still thinks something is wrong here.
SOLO

Thanks for the detailed feedback, we are passing all the info along to Hoosier and will be testing the 255's on my car as soon as the weather cooperates here in South Bend. It makes sense that more air pressure may be required because you have less volume to carry the same load than a 285 Hoosier.
If anyone has photos of the tire wear pattern, it would be a big help to see what you are experiencing.

i'm getting the same wear on the outside corner after 10 runs.
flipping 10 run tires seems a little excessive to me...
i wonder if the BMW racers on 9-10" wheels are seeing the same problem?

Sipe & Eric please post pics of your shoulder wear (as well as anyone else who's tried these tires).
Eric, when you ran the 245 Hoosiers, how was the wear on the shoulder? What were your cold pressures for the 245's vs the cold pressures you used this past wekeend on the 255's?

I know you've been on the 245 A6's for years. Wear issues aside, after your first national event on the 255's, what are your thoughts?

I seriously doubt this is a seasonal issue - or we would likely be seeing it with other sizes as well. I would guess this is unwanted side effect from from widening an existing tire/mold. I recall similar reports when the 275/15 first rolled out.

probably not getting the full benefit out of either one...
i saw a few extra .01 G's with the 255 vs 245 but within the noise.
steering response is about the same
as long as Hoosier keeps sending me free tires, i'll probably stick with the 255s.
you guys can help with that by letting me win, starting with the Lincoln Pro...
11 entered in BS so far out of 108 entries.

All systems GO today...Problem is I need to place a will-call pickup and it can only be done through SB on the phone, not locally or online. Somebody may want to rethink that strategy.

here is a picture of the corner wear i'm getting with the 255 tires.
after looking at it closer there isn't a great deal of wear but it is unusual.
is this what everybody else is seeing?

GGP does a cheese grater job on tires which is why the tire looks so bad...

Well, as someone who has landed jet aircraft on the runways of [the former] MCAS El Toro, I can tell you that the paving is more aggressive and harder than typical highway materials. As you would expect, it is optimized for traction and impact (Carrier style landings) as well as consistent longitudinal level.
I believe El Toro can be a beotch on tires...particularly if you are trying to control sidewall profile and roll over with high pressures...don't ask me why I think this...
I wouldn't take the wear that Goeke/Bauer and Sipe/Thompson experienced as indicative of the "whole story".

Lincoln - Hopefully, we will be ready to rock by then...
But the Blizzak's did just come off the car a couple of weeks ago...

This is similar to what we saw on our 255 fronts. Notice the slight cupping effect on the outside edge. This is where it wears funny and will cord in about 20 runs. I'll try to get a picture of my corded tire. There are in the RV in storage right now.

From Eric's photo and Joe's description, it looks like the shoulder to tread cap junction area is the high wear point. It appears to be similar to wear patterns I have seen on DS BMW's, GS/HS Mini's etc, but I agree, it's not what you normally expect to see on RX-8's with max front camber and only 10 runs. For this abrasive of a surface, I would recommend adding 5-6 more PSI and rotate tires front to back every 6 runs. You may be able to adjust the pressure back down on lower grip/less abrasive surfaces.

sorry, Chris, I just couldn't resist...seriously, though, the wear being seen wouldn't be acceptable, to me. I'd just stick with the 295.
