One of my shop partners just retired a set of gravel tires. I'm hoping I can pick them up cheap. What do you think of this wear? I'm thinking mount them with worst wear outward and run 5 degrees of camber?

Do It Sidewayz
The outside of the tire looks like what i would mostly expect. But the inside of the tire looks a little bit like this area is being overloaded a bit.

I'd look at camber, too much camber will mean you are putting all your power and probably more importantly braking through this section of tire.

Believe it or not, toe can also do this as well.

Did you swap tires front/rear at service?? you should!

Having said all of that, I do not know the roads at STPR....which makes a huge difference. We have a road up here in Ontario (GCFR) which will KILL a full set of tires in about 50km. It is soo packed down that you will regularly hear tires squeeling on fast cars.

32 PSI is not horrible, but maybe a little bit high if it is hot/dry, which it was at STPR no? I probably would have suggested around 30 HOT....but 2 PSI won't break the bank.

As for the age on any DMACK in North America...they will be fresh, I'd guess the absolute worst case is 16 months since the date of manufacture. Which by no stretch of the imagination is old!

yep, yep, yep, nope. roads at STPR are very hard packed, where its swept it may as well be tarmac. obviously that comes into play w tire wear, and with tall soft tread blocks theyre going to get abused. temps werent too bad in the forest, plenty of shade so the road surface didnt heat up too much, and most stages i would say were still slightly moist. not dried out and baking in the sun. tires are fresh, it isnt an issue of age. im saying camber is the issue.

im putting the car back on the rack thursday, ill dial out some camber. any thoughts on adding some positive toe?

I hope you are kidding, those tires look like trash.
