F150 LB carrying fairly light 8 foot Six PAC overhead about 1350#'s down mex 1 and back (hopefully) regular ply truck tires - 235-75-15. No extended
off road planned - should I air + - or = from the recommended pressure on the truck door jamb?!Crusoe - 2-19-2008 at 07:29 PM
Mojo.........If the camper is really 1350lbs....After you are through stowing additional items of 200 to 300 more pounds, that is alot of weight for a
F150. I drive a 1996 F150. I would reccomend 80lbs. air rear and 50lbs. front. It will help.......but also I would seriously look into some suspension
upgrades as well. Have a fun trip and good luck. ++C++UnoMas - 2-19-2008 at 07:40 PM
Mojo;
I don't think regular light truck tires will take 80lbs. air pressure. I would see what the max. air pressure is listed on the tire and at least do
that. You should also look into a set of bolt on overload springs that you can get at many tire outlets. Check to see that your headlights are not
pointing skyward as well............Been there, not good.

Uno......Any 6 or 8 ply truck tire rated at class D or E will easily take 80lbs air. you can easily and safely go 30 to 60lbs beyond tire
manufacturer maximan inflation readings. Good call on headlights........ ++C++Roberto - 2-19-2008 at 07:59 PM
Why speculate ... look up the tire ratings at the various air pressures and go with that. The recommended pressures on the door jamb are not specific
to the tires.

crusoe,
Have no idea what his tires are rated for, but if it is a highway driving truck, doubt that he an E rated tire. For safety I would not push the mfg.
recommendations especially in Baja. Lots of no where in between.

If somebody wants to drive Mex 1 w/ truck and camper on it (and additional stuff inside) and needs a website to learn about the tire pressure, I
recommend: Stay Home and learn to knee down next to the imprint on the tire telling what the max pressure is.pappy - 2-24-2008 at 12:26 PM
worst thing is to have them underinflated as heat will build up quicker when going down the road which will create a blow out disasterBob and Susan - 2-24-2008 at 01:12 PM
we use 80 in the rear and 70 in the front
e rating means 10plymsteve1014 - 2-24-2008 at 01:24 PM
I found this chart on the goodyear website. there is alot of good info. from the tire makers, you just have to look.
