Will probably put the car in for the winter beginning Nov 1. Go easy on me, you all-year-round West Coasters!

Anyway, leave the tires at full pressure? Brand new Exalto Michelin radials...
Half pressure?
Move it a few inches several times during the winter?
Buy those pads you can roll onto from Griot's Garage?
Put the car on jackstands and worry about sucking out the shocks?

Thanks,

Paul

When I first started in the tire business, we has an issue at Subaru Canada as a number of cars that had been sitting in their compound over several months had their tires Out of round.

It was determined by the engineers that since the tires were underinflated and the vehicles had sat over 4 months that the steel belts had "set" and a vibration could be felt within a particular speed range.

If not too severe, proper inflation and useage somewhat eased the symptoms. but not correct it over the short term.

Remember car tires also lose a pound of pressure every month not including the variable of dirty/leaky valves.

I would have your friend inflate his 911s tires to the maximum pressure on the sidewall
