[RH77]

The Integra is parked outdoors, and recently for about 3 weeks straight after some significant Winter weather driving.

Yesterday was about 50-60F, and I took it for a spin to haul a few items. Coast-down was terrible, as was FE. It turns out, the passenger-rear caliper is locked -- for the 3rd time (second in 3 years).

Then, while inspecting the problem, I saw that all 4 tires are cracking (which is a new problem). The sidewall and tread "attachment point" look to be falling apart. They have enough tread to keep another year -- should I worry and replace?

These are low-rr, Michelin MXM4s with about 40K miles, so not a ton of miles and not cheap. Last Summer was one of the hottest and driest on record -- so extreme exposure could be a factor.

Could over-inflation (50 psi) be the culprit, or just normal tire wear in this weather? I have not seen this happen on a good set of tires, even when over-inflated...
