50psi tire pressure???
Hey All
My jeep has 31" General Grabber AP tires on it, the front was looking a bit
low so I was filling it up and when I checked the tire it has it's maximum
xxxx lbs at 50PSI....
50PSI, is this correct? should I be butting that much air in these tires? a
regular tires ran 35psi so I was suprized to see these take 50, just want to
check it with you guys before I blow up a tire becuase it's overinflated....
thanks

What does it say on your door frame that is what you go by.

Re: 50psi tire pressure???
that tire rating is for the maximum capacity for that tire under maximum
load. Remember, it's not just a jeep tire. It's probably a small, or reg
truck tire too. you should go off your listed door frame, but I've found
that to be off slightly at times. if you don't have doors, it's in your
owners manual as well. I think my 89 yj is like 28 or something like that.

Re: 50psi tire pressure???
I would go by the tire pressure listed on the door and/or manual
provided the tires are the tires that came with your Jeep from the
factory. If they are larger than the stock tires, then go by the
tire manufacturer. I put 50psi in my 31" swampers on my 97XJ
when I'm driving on paved roads, and that is only because the
ride is less bouncy...especially during the winter months when
the road heaves up due to frost.
G/L,

Put in the 50 PSI. I say that because it DOES NOT MATTER what anything
other than the tire manufacturer recommends. The manufacturer has engineers
that have taken the time to design the tire so that it will last as long as
possible. You will destroy your tire if you alter that pressure too much.

Re: 50psi tire pressure???
Do not put in the 50 psi. Don't do it. As another poster posted, that is
for a maximum load on other vehicles. Here is what you can do to find the
right pressure for you in your Jeep at your weight.
Chalk up the tire and then drive it for a couple of revolutions on the
driveway. The right pressure is the one where the chalk wears off evenly
across the width of the tread. Easy as cake.

Re: 50psi tire pressure???
The reason that your tire pressure is set at 50psi is that your tires have a
thicker sidewall then what is found on your normal 32psi tire. Ergo you need
the extra psi to make sure that the sidewalls are seated to the wheel rims.
If your tire separates from the wheel rim the result will most likely chew
the hell out of your tires sidewall. If this happens and your tire was under
inflated at the time of the incident forget about getting any damages from
the tire company, you weren't following the manufactures specs. In other
words, it's your baby.
Keep this in mind. Most tire/rim separations due to insufficient tire
pressure occur during a turn at over 35 miles per hour. Ask yourself if this
were to happen would you be to keep your vehicle upright let alone under
control?
Be safe, follow the manufactures specs.

Re: 50psi tire pressure???
But that is not the recommended tire pressure it is the maximum pressure.
Finding out the recommended pressure is not done by looking at the max
rating on the sidewall.

Under normal loads, inflate tires according to the vehicle
manufacturer's recommendations, NOT the maximum pressure listed on the
sidewall. In any case, one should never exceed this maximum pressure.

This would hold true for tires mounted on a vehicle at the factory.
Your recommendation goes out the window when you change tires such as
different tire brand, type of tire, size of tire, etc. When this
happens, you go from the vehicle manufacturers recommended psi rating
to the replacement tire manufacturers recommended psi rating. Case in
point, my 97XJ came with Goodyear Wrangler 225/75R/15 tires from the
factory. Psi rating was I believe 35psi on the side door. I swapped
them out 6 months later with Cooper Discover 235/75R15 tires. If I
had stuck with Jeep/Goodyears recommendation of 35 PSI, then I would
have worn out the Cooper tires in 6 months provided I hadn't lost
control at normal highway speeds first because at 35 psi, the coopers
are underinflated! I would also have gotten pittiful mpg during the
short life of the tire as well.
I have 31" swamper TSL's on the XJ, and I keep them aired up at
45-50psi. This is my second set. The first set lasted 4 years
keeping them at 45-50psi and 95% of my driving was on asphalt/concrete
pavement (i've got a 50 mile daily round trip to/from work). Must be
doing something right.
The best bet is to contact the tire manufacturer to find out THEIR
recommended psi for the specific vehicle you plan on puting their
tires on.
