Tyre pressure help for 21"

[kilojade]

What tyre pressure are u ment to be running on the 21" tyres?

Have just got car back from diamond cut place and has tyre pressure warning light on. Went into the computer and it says there is 29psi in all 4. But also states front left tyre pressure low. Maybe it's a faulty tyre pressure sensor.

But 1st would like to no what pressures should be in them?

Have you reset them at 29psi? Should get rid of the warning. It's the option underneath Display Tyre Pressures in the MMI.
