How is tire wear at 30 - 33 ? I know historically the rears wear faster...But I'm wondering how lower pressures affect wear.

Thanks again!

• Adjust your cold tire pressures using an accurate pressure gauge.
• In the TPMS screen on the PCM, select winter tires then select summer tires again (or vice vera if you’re on winter tires)
• Then select whatever combination of option is closest to whatever you inflated your tires to between comfort/normal and normal/full load.
• You well get a message stating the TPMS has been reset and that it needs ~25km to record the pressures (no pressure will be displayed for a few miles of driving, usually less than the stated 25km).

I find it to be a bit of an over complicated procedure compared to other cars I’ve own/owned, but that’s how it needs to be done (it is in the owner’s manual).
