Tire Pressure

[telegoat]

I have the Toyo Open Country 225 75/16 Tires on the rig and they're definitely working well for me. Les Schwab has recommended several different tire pressures including 50 and 65 psi. I'm curious to know what tire pressures you're running?

I run my MT 315/75 16 E tires at about 62 psi but getting a bunch of numbers from us
won't do you as much good as checking the load and pressure limits on the side wall
of your tires and the weight of your van.

Les Schwab has pretty good prices, good products and good basic service but asking
for technical advice or some specialized service is playing Russian roulette. Some of
their people are competent and some are complete idiots.

Never tried this before, but it strikes me as reasonable:

Paint a line across each tire. The paint should wear evenly across the tire indicating even tread wear.

If the center wears first, too much pressure. If the outside wears first, not enough.

For off-road use, you want a slight bulge.

Different loads (weights) will cause the pressures to achieve these pressures to vary.

The Sprinter factory specs call for lower air pressure, 47 cold, in the front and 70 cold in the back. The front wheels are wearing as if the air pressure is too low. What are negative consequences of increasing the front wheel air pressure to equal the back tires?

57 front and 70 back.

10 ply "E" tires - 60psi Front / 80psi Rear

Toyos - 55 front, 60-70 rear depending on load.
