Remember that that is a MAX psi rating, understanding that if you check your air pressure cold before driving it may be at 32psi, but I have done several road test on many different tires on trucks & cars with some tires gaining as much as 6,7, even 8 psi after driving interstate for 3 hours & checking them when they are hot, like right after pulling into a rest area or gas station, just like being at a drag strip, you can pull a car off the trailer with 18psi, do a burnout & one run down the track come back to the pits & you may see 21-22 psi, constantly having to adjust pressure during your first 5-6 runs to get the tire to stabalize PSI at a specific tire temp.
So with saying that if you put 44psi in a tire with a MAX rating of 44psi, you may actually be running 50psi going down the road under heavy loads or hot temps. We typically use a rule of thumb of the MAX psi minus 8 PSI and thats what we set tire pressure at. It still amazes me the amount of people in the world that think ALL tires should be set at 32psi & how many quick lube shops i see using 32psi in every car. Take an E rated truck tire, its max is 60psi usually
, setting that tire at 32psi and you might get 10-15K miles out of it & the ride is horrible.
Just some FYI information on tire pressure...
