Hi Guys,

I have a 2013 RRS with 27/40 R20 on.
It felt a bit off the other day and when I checked the pressures, all 4 where 30 psi.
I put it up to all 37 for now but what do you guys use best?
Car is 90% just me and no towing.

Open the front door and recommended tyre pressures for different tyre sizes are there on a label on the car's body. 33 front and 36 rear for your car under normal load. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top

Great stuff.

Is this what people run normally or anyone found a nicer / better combo?

I always go by the manufacturer recommended tyre pressure. Current car didn't feel right after I picked it up from the dealer. Checked pressure and 50+ all 4 corners Recommended is 34 front and 37 rear Promptly corrected it. Still haven't got round to getting wheel alignment checked. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top
