Hey guys,

I have a 320d f30 2013 efficient dynamics

I just don't know what pressure to keep my tyres at front and back, the dealer is not helping as they say refer to the door sticker which now doesn't apply as i have changed to 19"!

I have just changed the alloys from the 16" to these nice shiny 19" 442m orbit grey alloys on bridgstone potenza tyres.

Front 225/40/R19

J8x19H2IS36
BMW 7846780

---------------

Rear 255/35/R19

J8.5X19H2IS47
BMW 7846781


Please help me on the front & rear / normale & loaded Pressures
I do alot of moterway miles and always check my presssure every week to maintain tyre health.

Thanks guys!

Most probably run in the mid 30's or so. I like closer to 40 since I'm on the interstates running 75+ much of the time and it helps get better mileage. Max for your tires is probably 51 or something, but you'd never want that much.

I have the same tires and run 36/38. Check your doorjamb.

Considering what is seen between different models, I doubt the 320d and 340i X-Drive call for the same pressure.
