Tyre Pressures

[Noodle30]

Stupid newbie question #52, what pressure should Bridgestone s03 inflated to?

[puffsorted2]

22 PSI

I haven't got SO3's on mine but believe the following to be the concensus between owners.

- SO2's were 22psi front and 24 psi rear (As supplied on the new car and recommended in the handbook)

But as the SO3's have a slightly stiffer sidewall a lot of people like to run them at 20psi front and 22 psi rear to simulate the same feel of the SO2's.

And the opposite for Toyos as they have a slightly softer tyre wall than the SO2's so use 24 psi front and 26 psi rear on these.

Pretty sure this is right but am sure that there are lots of other threads on here discussing this if you do a search.

Yep, its been done to death. I have SO3's and find that a little under the factory pressure is good so 21 front 23 rear. I tried 20 on the front and 22 rear but didnt like it...each to their own I guess

When I picked her up the previous owner had them at 32 all round !! It was like skating on ice

Anyone know what sort of pressures to run Dunlop SP9000's on. I`ve just had some fitted. I liked the way it handled on S02's, so want to try and keep it the same.

I would stick to the factory settings or there abouts, its sounds low but it's all to do with the weight of the car. Keep a eye on how the tyres are wearing, worn both outsides of the tyre means not enough pressure, worn in the middle means too much pressure, this can significantly reduce the life of the tyre.
I have the SP9000's fitted and can't fault them up to now.
