Tyre pressures on 225/40/18 E90 LCI

andytran · 02-03-2010, 02:44 PM

Hi all,

after replacing my 17s with none runflats, I am now looking at buying some 18s.

Ive been offered some replica MV3s (new) with new Kuhmo KU31 tyres for £510 delivered.

Im going to buy them, but have one question:

On the E90 (mines a 320d se LCI) what tyre pressures should I use for none runflat 18" tyres?

Your thoughts appreciated,

Regards

Andy

Tyre pressure is mainly related to width, so if you start with rating plate pressures for 225 tyres thats a good place to begin.

I reckon 2.2f/2.5r bar is a good start

Cheers mate,

Ive gone 2.3 front and 2.7 rear, seems OK but its early days!
