Tyre pressure

[MikeyH]

I’m sorry, I know that I am opening an old thread but I feel it’s important. Since I’ve had the car the steering has felt odd, I put this down to the tram lining that is discussed on this forum. However having read an old thread re tyre pressures I decided to check mine. The fronts were at 27psi and the backs at 29psi, I raised them to 30psi front and 33psi rear, this was what the book says for run flats, mine are normal tyres, a previous owner had written this in the book. My god what a difference, changed the whole feel of the car and it doesn’t feel any more harsh or bouncy. No more trying to put me in the hedge or path of oncoming cars or fighting the steering to keep it in a straight line. I’ve gone on a bit but I hope this is helpful to others.

I get pretty even wear 33/35 on mine.

I run 31, 33.

I've run the standard pressures (32/36/18" iirc) for years on non rft's.

I've increased the front now to 31 and kept rears to 33 as buzyg and it feels a little sharper. Sticks, do you find that yours wear evenly at 32/36?

Adjust them to suit your style, (only by a few psi from the book though)
Increase the psi and makes it sharper but downside is ride is harsher
Reduce the psi for more comfort but steering becomes sluggish
Book for me states 33/36, but reduced to 32/34 for a bit not give.

Yes the book for me is 30/33, but the plate in the car reads differently.

Very interesting to me too, ive been running 33/33 non runflats since purchasing 3.0si a few months back, ive felt the front end seems just a little too firm bouncy, im going to drop the fronts to 31 to see if its an improvement.

Someone posted this up.

I've set mine up to 34/36. Glad I checked as they were set to 18 all round!
