Really? It's not exactly rocket science. There's just no excuse for that. (By the way...you'll soon be in a parade - sorry, no ticker tape - regardless of where your tire pressures are.)

When are you guys checking your pressures? From cold or once warmed up? Getting heat in the tyres can have a significant effect on the pressures (ie increasing them) My understanding is you should check and adjust pressure when the tyres are cold. If you do it when they're hot they'll be under inflated when cold.

additionally if they are set correct when car hasn't been driven but with say 20°C (70°F) external temperature then when ambient temperature drops to say 0°C (32°F) they will be underinflated unless you put more pressure in.

There's quite a difference between acknowledgement that tyre manufacturers inform that "summer" tyres compounds lose much of their stickiness below 7°C and claiming tyre pressure doesn't matter, even if you qualified your statement with "doesn't much matter"

The pirellis seem especially terrible in cold temperatures. I've run Hankook ventus v12 evo all winter, including in snow, on rear drive cars with no issues. Previously also dunlop, falken, and michelin. I think next time I'll turn off the traction control, do a burnout to get the pirellis warm and see if they're any less bad.

Where's that one guy that doesn't want to read one more comment about how bad the Pirellis are for traction?????
