I live in the Cayman Islands where the average daily temperature is around 85 degrees year round. Summers are up around 90 and around this time of the year it may drop to around 75 occasionally. I have a '99 996 C2 6-speed. There are never more than 2 people in the car and it is used as a daily driver only.
It has Continental SportContact 2 tires. 225/40 ZR18 in the front and 285/30 ZR18 in the rear. Based on my location and car usage what would be the recommended pressures?
Thanks.

 

Check the pressure reading on your gas filler flap, it will tell you the correct COLD pressure. I use these settings and check them frequently as the ambient temperature varies dramitacally in NJ. Make sure you have a good qaulity gauge in increase the pressures a couple of lbs if your are on the standard cast wheels with poor qaulity roads. The extra pressure will help protect a little from bending your rims.

 

I am running Continental SportContact 2 tires. 245/35 ZR19 in the front and 275/30 ZR19 in the rear. Tire pressure cold is 36psi F + 44psi R. Doing fine so far.
