Hey gang

Just switched from 20” to 21” and the wheels and tyres came ready to fit. I didn’t see any direction on any of the tyres. They are Pirelli P Zero NFO. Drove for 15 mins so tmps can register.

Part of me felt like the front needed spacers while I was putting them on.

2 questions.
Do these have directions?
What are the psi for 21”?
I believe the tyres are all season.

Sticker inside the door states 38psi front and 41 rear with 2-up. Full load is 40 and 45.

The right rear tyre sounds like it’s driving over foam… just read somewhere that it has foam inside ?
