Dull Thread of the Month Winner! Tyre Pressures...

Hi Folks.

The 'standard' pressure for 205/45/17 is 2.5 bar (not sure what that is in psi) according to my wee chart on the car. This seems a bit high to me and even on non-runflats can make things a bit jiggly (and not in a good way) on the bumpy stuff. Mentioned this to a couple of other NMS buddies recently, and I think the consensus was that it was indeed a bit on the high side. I'm certain I used to run them a bit lower until I spotted the 'correct' figure! :smilewinkgrin:

It'd be interesting to see what others running 17's have found. Obviously having the correct tyre pressures is fairly crucial, but I reckon going just a tad softer wouldn't hurt the tyres and might add a bit more composure over lumpy tarmac. Open to suggestions!

Sorry this is a pretty dull topic, so here's a nice picture of Kate Bush to cheer you up :thumbs up:

I run my NON run flats at 32psi /2bar

36psi is 2.5 bar

Pah! The door jamb sticker for the 205/45-17 tyres on my Roadster says 2.8 bar, which is 41psi. And it definitely needs every one of those psi to give the best handling. I actually run my winters at 45psi.

I think there are some people who believe there is one 'good' pressure for all tyres irrespective of load or size - most tyre fitters seem to have a profound faith in 30psi as the 'right' pressure for every tyre.

I suspect the tendency for Mini owners to run lower-than-official pressures is that;
a) they don't really ever corner harder than their gran, so don't care about grip;
b) they wish they hadn't ordered sports suspension and are desperate for any softening of ride.

But I must say that lowering the tyre pressures on my (non-sports) car does nothing to soften the ride - if anything it seems slightly less crashy at full pressure.

Not at all if you look at my build thread you will see I run fully adjustable suspension with all my camber set for fast road use has even been set up with me in the drivers seat for best road use I find my clubman is very skippy with the pressure at full whack and a lot more planted at 32psi

Now you ask any of the members here who know me know how I drive and they will tell you I don't tend to hang around and I have done the odd track day here and there

^^ I'm in a similar boat to this (except R53) and I run 32f/33r after much trial and error

^^^ same for me on non runflats :yes nod:
The 19's on the Audi run at 36psi :thumbs up:

cant beat a nice bush :thud:

To be fair, this is one thing we can all change that can have a big impact on handling.

Forgot to mention I'm on Parada Spec 2's
