E93 255/35/19 tyre pressure conundrum/help

ciobbath · 04-25-2021, 10:40 AM

Hey all.

I've just got myself a great little 2010 E93 330d (UK)

I'm checking my tyre pressures but the front tyres are slightly smaller than the rears. The tyre size guide on the sill doesn't mention the size of the rear tyre, so Im unsure what the correct pressure should be - can anyone help:

The fronts (rfts) are: 225/35/R19 - 2.8bar (says on pressure guide)
The rears (rfts) are: 255/35/R19 - ???

I've checked forums/online and there isnt any pressure guide for that size of tyre for an E93. It also seems that the rear tyres arent OEM, probably fitted by the previous owner - Any help is most appreciated.

Cheers

I usually fill my tires to 2.5bar f/r

But also, that rear tire should have a 30 profile, not a 35. You're running diff diameter wheels currently

Thanks for coming back to me, appreciated.

The rear tyres were brand new from the car dealer and I have been told that they are the same size as what was on previously.

What options do I have here? Carry on or get new tyres and replace the brand new ones already on.

What a pain!
