What's the recommended tire pressure for 18" tires 235/45/18?? Thanks!
Thanks for the info... only reason why I'm asking is because I have a model 3 Performance and I downgraded to 18in rims and tires, so just curious to see what PSI pressure are for the 18in tires, but 20in tires are recommended at 42 PSI... because my tire pressure sensor was showing under inflation, so I put it at 40 PSI and so far so good[/QUOTE
Label as in a Swiss Model 3.

If I had a performance with 20" factory wheels/tires I would run at 50 PSI to help prevent damage from potholes. Also the load range seems inadequate for the tire provided.Recommended PSI doesn't change with a change in tire/wheel size.
Yup. I'm running lower for "around town". I've got a portable pump that makes bringing it up, as needed, really easy and a quality gauge with a bleeder that lets me set it more precisely than is probably necessary, so I don't have to rely on the TPMS or heaven forbid, the gauge of the portable pump. TPMS are sometimes of dubious accuracy and more importantly often you need to drive around with them to get them to get an updated pressure reading, kinda inconvenient.If you guys ever need the range on a long trip just increase the pressure. Definitely does make a big difference.

As far as PSI goes I set my 18" Pilot Sport 4S tires to 45 PSI cold. The thing is I set that at 60 degrees. It was 40 degrees yesterday and running at 41-42 PSI and eventually increased.
My car does feel likes it's on skates... really sticky skates. Per SammichLover I plan on checking the center and outside tread depth to make sure I'm not ruining the tires. If it is off 1/32 I don't care.
