235/50/16 Tire Pressure On 850 Series

[mid-eng350GT]

Hi,

Could somebody please tell me the correct tire pressure for 235/50/16 tires on the 850 series?

Thanks

did you try lookin' in the driver door jam there should be a sticker that lists tire pressures for the diffrent size tires avaliable for that car from the factory. if you have tres that aren't an exact match to the sizes on the sticker just pick the size that is closest.

If I had the car, I could look in the door jam, so I wouldn't be asking.

I'm asking because it's what I have on the rear of my Fiero. The wheels and tires are plus-sized for improved traction & handleing, so I'm curious what the factory PSI specs are from a car in which that specific tire size (rare in this case) was OEM for comparison purposes.

well really the tire pressure really depends on the vehicle more than the tire.things such as vehicle weight,supsension set-up, heat produced from the brakes,load capabilities, and intended performance from the car. all these thing can have an affect on what the tire pressure should be. since you have a car that is alsmost the opposite of what a 850 is i'd just play around with the tire pressures. maybe set them at the factory spec for your car and see how you like them. is the car a dialy driver or a track car.

Any time you plus-size you should increase pressure.

The car originally is 215/60/15 in the rear at 30 psi.

I am now running 235/50/16 in the rear at 34 psi.

I realize that, but like I said... only curious what the BMW 850 factory PSI specs are for 235/50/16.

Maybe I could call BMW dealer. Was hoping somebody here had a 850 with those tires and could look in the door jam for me.

sorry i guess i haven't really been giving you the real answer your looking for. it has been a while since i have messed with an 8 series. but if you are running 34psi in the rear that seems like it would be colse to the factory 850 tire pressure. you might be able to get the actual tire pressure fomr the dealer however they might not have that infomation at hand. they since you'd prolly be talking to somone in the parts department they might be able to ask a tech that might know.

Found out that the Audi that uses this tire uses 34 psi.
