?????
Are you saying they are RunFlat tires? (or since you're from Vancouver - tyres?)
I just looked at Nokian's web site and while they do make Run Flat tires, I don't think the ones to fit your Regal are.

OK, here's the deal: Passenger car tires will have a max sidewall pressure of either 35 psi (or 36 if the tire is based on the metric system of measurements), 44 psi, or 51 psi - for all standard load tires. or 41 or 50 psi for Extra Load tires.
So if the tires in question are for your Regal, it does not make sense that they would say 81 psi max!
But it does make sense the the LT tires on the Muso say 80 psi max. That makes them Load Range E's - very appropriate for a light duty truck.

Before we go there, let's clear up what it actually says. There is some amount of quirkiness in this and it is important we start off with good info!
