Bridgestone Blizzak LM-25V Winter Tire Pressure

CT_335D · 11-27-2012, 11:57 AM

I have a 2009 BMW 335d with Bridgestone Blizzak 205/50-17 non run flat winter tires.

Does anyone know the correct tire pressure for these tires?

New England (Connecticut) weather conditions.

The car manual shows 33/41 PSI (front/rear) for the original tire size of 225/45-17. The 205/50-17 size was the optional tire size for my car.

Thanks

Your manual doesnt give you the right pressures for that size? I was shocked when i actually read mine this year and it went over all different pressures for each car and tire size.

If you give your GAWR's ( Gross axle weight ratings) and the maximum load of the tires, I can calculate a save pressure for fully loaded.
If you also give the empty weight and configuration of the car ( motor in front for estimating the division between front and back axle) I can give you an advice for normal use ( 3 persons and a little load). Also need to know if they are standard or Extraload tires, if it states on the sidewall somewhere XL extraload or reinforced they are , otherwise iths standard load wich need a lower pressure.

I once got hold of the formula that the tire-makers in Europe use to determine the advice-pressures for Standard load and XL/Extraload/reinforced tires, and went running with it. Got much to know about it hovering the internet.

Found out that 36 PSI is the way to go.
