The recommended tire pressures are always on a placard that's affixed usually to the driver's door jamb. I believe for all types of wheels, it is 32 PSI cold.

If you are getting a TPMS low pressure warning, make sure you also check the spare. Tire pressure decreases by about 1 PSI every 10-15 degrees F., so going from summer to winter, you can lose four to five PSI - enough to cause a low pressure warning if you're not adjusting your tire pressure at least monthly.

If you drive aggressively, running a higher pressure in the front tire helps reduce understeer and keeps the outside shoulder of the front tires from being ground down as severely. The Rav has about a 60/40 F/R weight distribution but the same size tires all around, so it also makes sense to run the fronts a bit higher. I'm a fan of 37.5 front, 36.5 rear.

If he's got a 2011 Sport model, there shouldn't be a spare to check!? Shouldn't it have run-flats???

I think you have to have the sport model to get SAP, which gives you the runflats and deletes the spare. In our area, I believe practically all sport models come this way, but that's only because the local dealers seem to have conspired to order them this way.
