Re: Michelin Power Race Pressures Cold & Hot?????
You & your friends misinterpreted that info.
Cold pressures mean just that... when the tires are cold. You should have set them cold, and pretty much left them alone. You can certainly adjust the pressures hot... but the pressures you'll be shooting for will be at least 3-5 degrees higher than cold. Your tires were significantly under-inflated.
BTW - the 21-22 rear pressure is only for PR-series tires, not the normal 'power race'.
