Maxing out tire pressures...
I've read in a couple of places that to improve the ride some people "ignore" the tire pressure recommendation inside the door and inflate their tires, (often just the rear), to the max inscribed upon...
Forum Discussion
the car maker intends the advice pressure for GAWR of vehicle and after 2000 even rear pressure needed for the maximum load of tires, called reference pressure ( Pr) in the official universal formula for calculating loadcapacity for a sertain pressure, wich I once got hold of and went running with. This is not the maximum pressure of a tire ( Pmax) .
so if you searched this forum right , you should have stumbled on my reactions with also link to a map on my one-drive with extra save pressure loadcapacity lists. but OK I will give it again here.
Extra save pressure/ loadcapacity-lists
Yours 44psi maximum pressure makes me conclude your tires are Persons car tires ( P-tires), they only give Pmax on them ( also for XL/Reinforced/Extraload). From LT tires C-load and up they give the Pr on sidewall mostly like this "maximum load xxxx lbs AT yyy PSI( Cold).
For P-tires Pr is in American system always 35 psi/2.4 bar and European system 2.5 bar/36 psi with exeptions to lower.
For XL/reinforced/Extraload Pr is 41 psi/2.8 bar (USA always) and 2,9bar/42psi( EUR with exeptions 2.8/41 and 3.0/44).
so your given advice is rear for Pr of tires so maximum load of tires up to 160km/99m/h ( Q to V speedrated).For higher speed Pr has to be highened up with a system depending on speedcode.
So the 35 is already for probably even higher load then GAWR rear and 44 psi most likely gives bumping.
