Recommended tire pressure for 17" style 5 rims?

[NielsGalan]

Hey guys. Summer's a-comin' and I've just put on my "new" 17" Style 5 rims. The bottlecaps have been sent to a well-deserved hibernation.

Problem is, I have no idea what the recommended tire pressure is on those things (the style 5's that is):

The tires are Avon-something and the size is 235/45RZ17 94Y.

Any recommendations?

I'm doing psi 39 front, 41 rear.

The door jam should list specs for various wheel sizes...I think that's the spec for the 17" wheels.... (at least that's what I'm using on my 525 w/style 5s)

Haven't seen my car in 4 months, can't wait to get home and clean it up, tune up, fresh fluids...etc. and take a nice country road spin through the hills.

The E34 owners manual lists the same tire pressure for the 15" tires and 17" tires...

Innaresting ...

Neither my manual nor door'thingy states anything about anything larger than 15" rims. I wonder if that's a US<>EU thing.

Thanks for your help.

I run 41 rears and 40 fronts.

You probably have Avon Techs. Those are nice all season tires. For the price, they can't be beat.

NB: I notice there is no 535 in those listings ;)

Obey your local speed limits!

I think this is more subjective preference. On my 17” wheels, I like to have 37 psi front and 33 psi for the rear (that’s cold tires). Remember, the tire pressure will increase as they become hot (3-4 psi). Since I don’t usually have rear passenger(s), I like this setup. It seems easier over bumps. Many recommend that you should have the rear with more pressure than front for these cars but for me, this works the best for me. For my winter tires, I have 16” wheels and I like to use 32 psi front and 35 psi rear. Correct me if I’m wrong, with more front pressure, it will increase over-steer or decrease under-steer. With more rear pressure, it will decrease over-steer or increase under-steer. I think it is more of a preference. Whatever feels the best for you.

The info is from my 1995 owners manual. What's a 535i...is that one of those "OLD" BMWs...like an e12 or e28 or somethin' ? :D :p :D

Ahh...just j/k...somebody will have to check their 535i manual...or the sticker on the side of a 535i's door.

ditto. That's the spec I found by searching the forums--I believe it's what is recommended for 17" on an M5
