Proper inflation #s?

[bmwm3n528]

I guess there's no concrete answer, but wondering what you guys might use that have 205/50R16s or something similar.

At the moment I've been running 33F/36R without any real significant tire wear, and seems to be provide relatively neutral handling. Just wondering though.

I have a similar question, but have no idea. I run 32 F/R. 205/50-15 on Euro Weaves.

40 in the front
80 in the back

Tire pressure depends on the actual tire itself, size, use, and driving style.

I usually run 35-40 psi F/R and I never stagger my pressures (especially so much)

On low-pro tires, I try to keep the pressure around at least 40, gives a bit more rim protection.

Whatever you do, read your tires and make sure you know the max inflation, and never fill them up too far

I'm doing the same, either 31 or 32 psi on euro weaves 205/55/15 tires.

32-34 psi.

w/bottlecaps?

Believe the specs are on the door jamb for original wheels.

Eh, it's not that simple.

Optimal tire pressure depends on a lot, for example:
o Tire model
o Tire size
o Suspension (geometry, compliance, etc)
o Road condition
o Desired use (road, track, auto-x, drift, etc)
o More...

Really you just gotta feel it out for yourself, on your own car. Other's numbers aren't very useful.

I was afraid of an answer like that. Thanks.

[PeaveyBassist]

Yes, I was on bottlecaps. Everyday use I run 32-34psi but it doesnt bother me if its anywhere between there. Autox with Azeni rt615's I ran around 45psi cold or so and once heated up they are usually around 47-48psi.

Yeah, I'm aware that all these conditions come into play, was kind of looking for a range more or less that might be good for my tire size listed.

Anyway, yeah...It's hard to give a concrete answer.

ok... noob question but w/e, dont know if you dont ask.


where it says max pressure (i think some say under load? not sure) is 35psi, but when you put it at like 33 or 34 and still doesnt look full, wtf do you do. go to 35, or leave it at what it is and say its safer that way?

i leave it at 33-34 for daily use on city and highway driving.

any input?

what size tires are they? Maybe the load rating on them are too low for your car
