That's the recommended in the works manual although 40psi for max speed if memory serves me right. I run mine at 32 lb all round...

Is that assuming it has the original size tyres fitted or like me I have slightly wider tyres and would they be the same pressure.

The 32psi tyre pressures quoted by Jaguar are based on 5" wheels and 185 tyres (although after much experimentation I prefer 30psi front and 34psi rear). If you are using wider wheels and tyres you probably should consider using the tyre pressures quoted for the S3 - for normal use 24psi front and 28psi rear.

A matter of driving the same route, which should include a mix of roads, several times over and lowering the pressure by 2psi for each run. You will quickly find the pressures that suit you and the tyre/wheel combination. One of the pitfalls in changing specification I'm afraid as Norman did all the testing for you and came to a learned conclusion.

Take a look at these recommended pressures for some examples of tire pressure for E-types:

David, out of interest what differences did you feel you achieved with your preferred tyre pressures?

More over-steer which suits my driving style. I was reading Dennis Jenkinson's autobiography and he said that after driving his E-Type many thousands of miles through Europe he settled on 30psi front and 35psi rear which fairly closely matched my own observations. For the hell of it I tried 35psi in the rears but I found it made the rear end a bit too skittish. When we embarked on one of our European tours I upped the pressure to 35psi and with a boot full of luggage it worked perfectly.

Thank you, David. Being more pedestrian in my driving style than you or Jenks methinks staying with 32 all round might suit. However, you've given me something to think about.

I have had a great deal of luck with 28 front, 30 to 32 in the rear depending on load. Makes the ride just a bit softer, and a touch more over-steer up front. In the end, just a matter of taste, and doing your own testing, which is always a bit of fun.
