MT DR center wear
Had my mt dr 275 40 17 for about 10k miles. Kept them at 32psi for street use. The centers are worn much more than the sides. This is my first set of these tires. Before you tell me they had to much air 75-100% of max psi is recommended by MT for street use. 44 psi is max on these tires so that means 33psi for street use. I guess these are truly a track tire meant to be ran with 20psi or less huh?

I think you are running more psi than most people probably run in those.How wide your rims are would also affect your tread wear.I can tell you that I have some MT 275/40/17 dr's also on 9" wide 10 spokes and run 27-28 psi on the street and they bow out in the center a little.Actually I think you did pretty good if you have 10,000 miles on those tires and they are not worn out.I would be happy with that-those tires aren't designed for good wear you know.

You should chalk line every tire on every car with the tires up to operating temp and drive it down a dead level road (no Crown in the road) and start at max pressure drive a couple of hundred yards and see where the chalk is worn. If its worn in the middle and not the sides, the tire has too much pressure for the load on it. Drop the pressure until the chalk line has worn evenly across the tire.
Once you have done that, you will have inflated the tires to the proper pressure required for the load it is carrying. Up or down for that you need to experiment for your best racing results for the conditions on the track!

For Lawsuits so you dont blow a tire off the bead from cornering too hard!

Or just do a tire cleanoff on a good road to see the black marks. Stripes on the outside, blank in the middle means not enough air.
Black strip in the middle with no outer marks, too much air, adjust to get a full black mark on the ground that matches the width of your tire.
