I've used 303 Aerospace Protectant on my 2nd and 3rd sets of tires and it has helped defer the appearance of sidewall cracking. I apply it 4-5 times a year, both sides of the tires, very liberally.

You noted how light these tires are. I get a good flat footprint running 22 psi front, 20 rear. I saw tread 'rounding' at higher pressures.

Years ago I saw Dennis Olthoff at VIR, and I asked his opinion regarding tire pressure for my Goodyears. His felt the correct pressure was achieved when tread scuffing was noticed about halfway around the tread's edge radius. The 22 front/20 rear showed that type scuffing on my tires...when on a road race course.
