forzamilan10 · 11-13-2012, 11:31 PM

johnca · 11-14-2012, 11:30 AM

38 all round for me..

Brissyjohn · 11-14-2012, 02:26 PM

What the tyre placard shows. 220 kpa front 260 kpa rear or 260 kpa front and 310 kpa rear depending on load and conditions. I mostly use the high pressures

Hazey82 · 11-14-2012, 05:04 PM

place card says 33f 35r I run 36 all round

zabalzae · 11-14-2012, 05:12 PM

36 all around

Chewy · 11-14-2012, 05:41 PM

40 all round

Worx · 11-14-2012, 06:50 PM

I run 8PSI most of them time.

DamoBMW · 11-14-2012, 07:14 PM

260kpa front, 305kpa rear (psi is about 38 and 44)

It's between minimum and maximum on the placard for my tyres.

Bemwe_03i · 11-14-2012, 07:15 PM

35rr 33 fr on 18s

trive2 · 11-14-2012, 10:47 PM

38 front, 42 rear.

Car understeers so I like the extra bite in the front, plus its good for fuel economy.

steve.k · 11-14-2012, 11:08 PM

All up 160Psi

Mitch E46 · 11-15-2012, 01:01 AM

Usually 38 Psi all round on 19x8.5 square set up. Although I've been trying out 40 Psi all round and I'm liking it.

It's all a balancing act. You want the tires to have enough air to always have the contact patch on the pavement. Anything less than 40 psi cold in my car will cause the tires to roll slightly.
Too much is a bad thing and too little is a bad thing. This goes with tire pressure, suspension softness, alignment, etc... It's all a crazy balancing act

Keep in mind this stuff really isn't relevant in street driving

DamoBMW · 11-15-2012, 02:20 AM

^ What air pressures do you use in your watermelons?

On a mountain bike or rock crawling truck, yes. Not the case with an E46. Less pressure does guarantee more rolling resistance though.
