What would you recommend for front and rear tire pressures on factory OEM wheels and tires? Although my tires are new (Michelin), sometimes it feels like it's slipping at 75Mph on a curvy road. I have an 04 996 TT Cab with X-50s.
Thanks,

For road use follow factory specs which are mentioned under the luggage lid.

Land Jet

36 front, 44 rear.

I would follow the factory specs mentioned above. However, I have lowered my pressure just a little bit as the factory spec pressure seems to get "greasy" once the tires are warmed up. I try and hit the 36, 44 when tires are warm.

Factory pressures ok by me. Be sure your tire pressure gage accurate.

Tires probably not slipping at 75mph on road unless you're pushing the car and possibly driving too fast for the road or conditions.

Remember the tires on the car are high performance tires and as such are not well suited for use in colder temperatures. If it is colder where you are it would be wise to consider slowing down at least for the sharper corners cause high performance tires not as grippy in cold weather, and they won't be cause they'll not get as hot as they would in warmer temperatures.

Under emergency braking they'll not grip as well either and emergency stopping distances can be increased.

Sincerely,

Macster.

I run 42/34.

I vary it according to the tires I'm running and whether I'm on the track. I run Kumho Ecsta SPTs on track day and start with 40 rear and 32 front. After a 20 minute run session, I'm at 48 and 40. The Ecstas are great track tires, as long as you put air in them to stiffen the sidewalls.

On the road, with Potenzas, I'm running 42 and 34, slightly down from factory specs. These tires are LOUD and harsh at 44 and 36. They're not that much better where I'm running them. I don't think I'll use Potenza S02As again. When they're gone I'll probably try Michelin PS2s.
