Tyre Pressures
 

Hi folks.

I'm guessing this question has been asked many times, but what tyre pressures do people use in their Boxsters? I drive a 2003 'S' and am running 30/36 lbs. front/back. The car has 18 inch wheels with nitrogen filled rubber at present, in its

Front: 225/40/R18
Rear: 265/35/ZR18
Falkon tyres.

I'd be very glad of your insights / ideas.
Thanks heaps.

Well first of all you spelled Tire wrong :p

USA factory spec is 29/36
I generally run 30/36 as well. I prefer the handling that way

You might try looking on the door sill and then the owners manual.

The tire pressure placard is not on the door sill, its on the gas door

30/36 is the perfect baseline. I like to go as high as 34psi in the front if the roads are smooth enough/tires are balanced good enough.

34psi in rear if it's just me in the car. (mimimum weight)

Tire / Tyre ?
I guess 'tire' works for American english.

Thanks for the help. 30/36 is the recommended figure; I'll try (tri?) 32/36 sometime but on our goat-track B roads, 30 might be the way to go.

Just messing with you mate.
Welcome to the forum

I would try some different pressures, and see how you like the changes in handling. Factory pressure tends to have understeer

Btw, we need pics!

my tyre pressure is under my frunk. :) And, as tire "tyre" manufacturing changes, so could optimum pressure. AND, what kind of driving you are doing...AND different brands of tires with different rubber characteristics. I'm running the factory spec tyres, whatever they are, Bridgestone? Firestone? Anyway, factory tires and 30/36. It rides rougher for sure, corners better. If I drop it to 26/32. Smoother ride but then the suspension doesn't feel as tight. Due to squishy tyres.

There have been no changes to recommended tire psi for 986's since they were 1st made in 1996, assuming recommended tire sizes are used.
