Tyre Pressure Recommendations
 
What tyre pressure do you guys have on your e53's ?

Currenty own a 2003 4.4i with 255/50/19 fronts and 285/45/19 rears.

Thanks.

My 20" wheels and tires recommend 32 PSI front and 35 PSI rear but I run 30 all around to soften the ride. It felt a bit harsh at 35 PSI.

I run 36 all the way around on my 20's. On all my vehicles really, regardless of wheel size. I think everyone has there own preference.

Is there anywhere online where I can download a copy of the handbook for my 2003 4.4i ?

Not sure, I just Googled 2003 BMW X5 Manual pdf and that was the first link that came up. Maybe dig around a little and see if there is a UK RHD version :dunno:

Plus 1 on these settings with 20" tires. If you use 35/36 psi in the rears you will have high wear in the center and you will be at the cords in 11K. All of this is assuming you normally run/drive with 1-2 people like most of us. All bets are off if you are racing on your daily commute! :)

With the skinny 19" wheels and tires you will have to run higher pressures just to keep the contact patch at max. Upgrade to the big boys!

I haven't experienced this. Will certainly change my habits if I do though. Usually don't have anyone in the vehicle with me either.
