tyre pressure chimaera?

[paulsmith]

please could someone advise what tyre pressure is best
for Chimaera front and back tyres...many thks

[Steve_T]

Handbook gives 22 front, 24 rear. This works ok for SO2s, but for SO3s, best to drop to 20 front and 22 rear because of the stiffer side wall.

I was advised 21 on the rears for S03 after the additional wear I got in the centre at 22.

I found these pressures too low for track work - but for round town driving on the S03's I use 23 front, 25 back. These are still too low when doing excessive high speed cornering as the tyre rolls too much.
The tyre pressure gauges are obviously important as they can vary - especially petrol station gauges. I use an electronic gauge which is excellent, and very easy to read very accurately

The optimum pressure will vary with tyre size and suspension geometry, and if you're getting serious then also according to how much tread there is left and what your suspension settings are. But 23/25 does sound on the high side for standard size S03s on standard rims?
