Tire pressure ?
Does anyone have a Ranger regular cab long bed 2WD V6 with factory 235/75R15 tires on it? If so could you tell me what the factory sticker say to use for tire pressure?
My Ranger has that size and they are not stock so my sticker does not list them.

The reason I ask is: "My Ranger has that size and they are not stock so my sticker does not list them."
I have been running mine at 32PSI same as Firestone calls out for my Explorers. The door stickers on those are way low which contributed to the "exploder" problem.
Thanks for the info re supercab/shortbed. At least I know I am in the right ballpark.

Yeah, I got the part where your tires aren't stock. I just found it odd that the fuel filler door showed a regular cab long box truck.
Anyway, even though it says 30/35, I always run them at 35 all around. Don't know why, I just do.

My Ranger has the 235/75R15 that aren't stock, either. It had 14"s on it from the factory, but I run 35 psi all the way around, too. Never thought too much about it. It rides well enough, even though the speedometer is off, and I just adjust my speed, accordingly.

Mine had the 14's also but I changed them out this spring with a set of 15" Bronco-II rims. The selection of suitable 14" tires was slim. My speedo is off by about 8%. I need to crawl under there and count the teeth on the gear and get a new one. It throws the poor computer off a bit the way it is.

jinx102672 - The side-wall of the tire is not the place to look.
Torque1st - The factory recommended PSI is a compromise of ride quality, and average load capacity for a given size OEM tire. The Explorer tragedies were a combination of poor quality + lowered tire pressure to compensate for the crappy ride it had.
Think of it in terms of weight and load. Compare any small tire with any big tire on your same truck and it will take more PSI in the smaller tire to keep the tread flat on the pavement and not bowing out the sides than it would for a larger tire with the same/similar load capacity. In other words you should have about the same or less air in your larger tires (assuming they have similar load ratings) than you did the stocks to keep the best contact with the road. The weight of your truck has not changed so a larger tire with the same PSI or more, in it will tend to wear down the very center prematurely, and make it somewhat squirrelly to drive. Hope this helps.

Someday I will get an onboard air system so I can air the tires up from inside the cab, probably about the time I get a mil-spec HumVee.
Anyone else that is running 235/75R15 tires on a reg cab Ranger have a door sticker that lists the factory pressure?
