Over-inflated spare tire?

[Hacksaw]

Apparently they inflate all 4 tires and the spare to ~55psi from the factory and dealers don't generally reduce the pressure in their pre-delivery inspections. On the dash display, my spare reads 55psi (door jamb sticker says it should be 33; not sure if it's the same tire as the main tires).

Anyway, the spare is installed under the vehicle with the inner side of the rim visible. Do you have to drop the spare tire in order to get to the valve stem and deflate it, or is there a way to reach the valve stem without that hassle?

Welcome to the wonderful world of underside mounted spare tires. There are a multitude of options out there for a solution.

I was able to see and get to the valve stem to check pressure. Did not have to drop spare.

Its reckless by Toyota/dealer to let a vehicle go out with that knid of over inflation.

I use the factory’s recommended tire pressure as a baseline. I let my tires tell me how much to inflate. Pay attention to the wear on the tires. I drive everything like a car. Fronts generally wear on the outside due to cornering. Rears tend to wear the center. I anticipate a little more air in the front and a little less in the rear.

I agree. How could it possibly be acceptable to not check and set the tire pressures as part of pre-delivery inspection? It makes me wonder if they really check much of anything if they neglect something so straightforward.

Which trim level do you have? I think the rim that the spare is mounted to has different designs for different trims (different numbers/sizes of cutouts that would allow access to the valve stem from the backside)

Mine is an SR5, Stock OEM spare. Valve accessible through hole in wheel.

My door sticker on an SR5 has 33PSI for all four tires and 60PSI for the spare.

On the ORP, you have to drop the spare to check/add/remove tire pressure. It's a standard wheel and tire on the spare, so I guess the spare should be part of tire rotation on the ORP.

I wonder if people who got the optional TRD black wheels also got a matching spare? Probably not, so those folks would just rotate within the 4 tires/wheels it's wearing.

PS, anyone with an ORP, especially if you've never had a 4runner before, I'd recommend you pull out the tool to lower the spare (in the lower right compartment (with the liftgate up)), assemble it (3 pieces), pop the plastic cover off for inserting the lowering tool (the cover is visible with the liftgate up, at the top/middle of the bumper, it's a plastic rectangle ~1.5" x 5") and lower it a couple/few turns counter-clockwise, then crank back into place. Mine was immensely overtightened from the factory and took some effort to break it loose. The whole process to test it out will take you 5-10 minutes at most, and it's worth knowing in advance how to access the spare, in case you do get a flat.
