Tire pressure for towed car on dolly

Hi everyone!

I was getting new tires installed on my car and mentioned to the guy doing the installation that I would be towing my car on a tow dolly next month. He said that I should increase the rear tire pressure to 40 - 42 psi because the weight of the car would be putting pressure on the rear end of the car. Is this correct? To me it seems that the dolly is carrying the weight of the front end.

Also, how should I handle tire rotation? I will be putting around 1500 miles on the rear tire on my trip back north.

Any suggestions would be appreciated.

Since the car is sitting on a slight uphill angle it is true there is more weight on the rear tires. I doubt it is significant. There is no need to rotate tires on a 1500 mile trip. My opinion is to air and rotate tires the same as you would if not towing.

My tow is a Mini Cooper on a dolly.

Was it a tire store owner or the guy who puts tires on ?

I don't imagine an appreciable difference in weight, on the rear, with the front on a dolly.

We don't add air when adding passengers or luggage.

Maybe if we were carrying the front on a hitch, like a trailer.
