Hi all

This is my first post...

I have a 718 with 20 inch wheels - 265/35R20 on the back and 235/35R20 on the front. Standard issue Bridgestone rubber from the dealer (unfortunately...)

The manual suggests 33psi all the way round and i have had them inflated with nitrogen (it was £4, so what's the harm!) and it gives a pretty firm ride and not the greatest lateral grip.

I have noticed that under 'normal' driving conditions the tyre pressures quickly rise to 35-36 PSI and on somewhat more 'spirited' driving it can go to more than 40psi... In fact, on a warm day/road... WELL above 40!!!

This is my first car with tyre pressure monitors so i am OBSESSED!!!

I was wondering what pressures you all run and if you have any suggestions/recommendations?

Thanks!
