275/55r20 Tire pressure?

Let me start by saying, IM SORRY.

I searched high and low and could not find a clear answer to my questions.

Finally made up my mind and put a set of Geolandar G015 275/55r20 on my stock limited wheels.

Load rating on this tire is XL so still a passenger car tire with a higher load capacity, not an LT tire from what I understand. Still slightly confused on this one. To add to my confusion on this. This is a 6 ply tire, with a max 50psi rating. Doesnít this line up directly with a C rated LT tire?

With the XL rating in mind, what tire pressure should I be running? 32psi like Toyota recommended for the stock 245/60r20 that was on there? Or something a little higher? Max psi stamped on the tire is 50psi.

Appreciate any input.

Keep with the 32 PSI which should be on a sticker on the drivers door jam. That is the pressure on my SR5 sticker, too, and also the TRD OR and Pro which has more rugged tires.

The Max pressure (50PSI) is for max tire load, which you would never encounter on a 4Runner.

Thanks for the input fellas. I increased the pressure to 38 for now and itís seems to ride much better than at 32. Harshness over bumps has decreased with the increase in pressure.

Iíve sent Yokohama an email, hopefully they can get back to me sooner than later.

Interested to hear from someone with a limited whoís running the same size tires as this seems to be a pretty common size swap.

Thereís no way this pressure change is correct:

Yokohama responded with...

27psi.

32 feels way too squishy, canít imagine 27 is gonna be better.

Sticking with 38 for a couple thousand miles and keep an eye on tread depth readings.
