Should I increase the front tire pressure more than the rear (front wheel drive) above the recommended pressure to support the weight of the engine?
How much do you weigh?
I sometimes put an extra pound in the front but no more...these days, with smaller engines, the weight differential ain’t much and the listed pressures are close a great starting point...have been going a half pound extra in the front and about 2 pounds lower than ‘recommended” with my Mercedes GLC 300 because the run-flat tires have really stiff sidewalls and it softens the ride a tad w/o any noticeable loss of stability or having anything look like a low tire does. In the Winter I pump them up a tad because during the Summer, starting pressure is when it is in the 70s in the morning and the days get up around 90 down here...so the “softer” start is really about what’s recommended once the day warms up.
Yep, and it's in China. Back in the day we Americans chiseled our Finnigan pins out of solid granite, but this new stuff falls apart first body you run over.
When was the last time you changed the air in your tires?
Old flat air handles worse than new fresh air!
I hear helium works well, too.
Unfortunately, that came too late to prevent Ralph Nader's hit job on what was actually a very nice car in its later years.
HumVees had a Central Tire Pressure System with
an external line to an air compressor mounted to the wheel hubs.
Mayny SUVs have lower recommended pressures to help keep them from rolling over. The tires slide sideways rather than provide lateral grip enough to roll over.
Of course electronic stability systems have reduced the problem with the tire pressure / roll over problems.
Yes. I used to run a lower pressure in my old wrangler. It did help with stability. On my front drive sedan the sticker says 28 psi. I run the fronts at 30 cold and the backs at 28. The steering is more responsive and the tires don’t wear on the outer edges anymore.
First day: Doesn’t know a problem from a question.
Did not the engineers who provided the "recommended pressure" know which end of the car the engine was located?
LOL they designed the tires first.
Use the manufacturers recommended pressure as on the door plate. However, get a quality tire gauge and check the pressure monthly and especially before making long trips. Check the pressure with the tires cold as first thing in the morning before the vehicle is driven. Note tire pressure changes with air temperatures. Thus it is important to check the pressure when the seasons change. Some tire dealers use nitrogen to fill tires... offers some advantages, but not necessary IMHO.
Remember Fina’s Pink Air?

1961, Fina’s Pink air campaign!
Just a bit before my time...
Of course it does. The difference to using just "plain air" from your local gas station is the lack of water content in pure nitrogen. The water content in "plain air" is more susceptible to temperature changes...if you have a compressor with a water separator to provide dry air..same same...
A simple water separator would not solve the problem. If it would, race car drivers wouldn’t have to underinflate their tires and wait for them to warm up to get full pressure. They would simply put in dry air. It may be possible to get all of the water out of air, but a simple separator won’t do that.
