stuarty Posted April 2, 2012 Share Posted April 2, 2012 I bought a new bmw 320i m sport plus about 6 weeks ago. Thought i would check the tyre pressures. Problem is the information sticker located in the drivers side door sill states my front tyres (225/40/18 W) should be 2.0 bar, think thats around 29 psi and the rear tyres (255/35/18 W) should be 3.0 bar think thats around 43 psi. Does anyone know if this is correct seems really hich for the rears. Big difference between front and rear! Quote Link to comment Share on other sites More sharing options...
Gudzy Posted April 2, 2012 Share Posted April 2, 2012 If its any comfort my dads 5 series has a 6psi difference front to back. The tyre sizes are different on yours front and back though so that could be part of the reason why they have a bit more of a difference.

Need to contact bmw about this. 2 bar seems low for the front and 3 bar seems really high for the rear! Quote Link to comment Share on other sites More sharing options...
Gudzy Posted April 2, 2012 Share Posted April 2, 2012 My dads rears are 2.7 bar and the tyre sizes are 245 40 18. I thought the rears were quite high when he first got it and I remember doing a search and found that it was normal. What's written on the inside of your door is likely to be right, but of course there is no harm in checking... Quote Link to comment Share on other sites More sharing options...
