What is your tire size, are they on LSS wheels or wider wheels, street use or track use???
My 205/45R16 front on 7" wheels are at about 22 lbs cold.
My 245/40R17 rear on 8" wheels are at about 24 lbs cold.
Watch for wear in the middle of the tread on the rears, reduce pressure before you wipe out the water channels. Expect to go through 2 to 3 sets of rear tires for every set of front tires. BTW, I love these tires.

205/45/16 and 245/40/17. Rims are 16x7 and 17x8. All street use. These tires are nuts. I never heard my wheel carriage being hammeree by pebbles as much lol.

Those ding dongs at the tire mounting place set the psi at 60. Not sure why they did that.

Probably to set the bead of the tire; they just didn't let them back down afterwards (oops).

I drove about 5 miles and noticed that the steering was extremely light. Even lighter than the 195 tire that it replaced. Pull over and checked the pressure with a guage and my eye balls almost popped out of its socket. Dialed it down to 20/26.

Wow, very dangerous. You should read the shop manager the riot act.

At 20 psi on front, you may get some sidewall roll.

I just got these last month for non track use. Guessed at the same 25-27 psi stagger I use on Yokos on the street. Seems right.

Andy,
I started my rears at 28 pounds. I found out I was wearing out the middle of the rear tires. Watch the rear wear very carefully; be prepared to lower the pressure.

 

[Nessal]

Hmmm I'll probably up it to 23/26? What is your opinion on that?

 

[addertooth]

For my altitude and driving style, 22 front and 24 rear (cold on both), provided the best balance between wall flex and consistent wear across the tread surface.
Remember, our car is very light; higher pressures cause the center of the tread patch to bulge outward and wear out.

Thanks for the tip. I'll try it a bit lower.

The tires themselves are very nice for everyday driving. Driving on AO 48s is both expensive and shaky in a storm. These seem like they don't affect the steering feel much but still give a bit of standing water capability.

22/23 is what I use on my Toyo R1R to get even wear. Middles on the rears were wearing fast when they were at 27psi.

Just dialed it in to 22/24 and see how it wears. Thanks guys.
