I dropped them back to 35 (that's what I keep my F150 at), but upon looking, the sticker on the door says 30 PSI for that tire size.

Another vehicle is also 5 PSI too much imo... inflated by a garage who installed them.

Anyways ... seems as if the recommended PSI on the vehicles' stickers is what I want to go with.... what say ye?

Thanks!

I usually go with the recommendations on the sticker. Actually, I usually add 2-4psi to the numbers on the sticker, that gives me a little extra time as they slowly lose air.

For your mom's highlander, it's probably not a big deal assuming she's not a speed demon. It's probably fine to start at 33-35 and then top them up when they get down to 27-28 (since the reco is 30). I find that for most cars in most situations, there's a range of 5-10 psi where performance is similar, so I start at the top of the range and top up when I get near the bottom of the range.

I usually use the door sticker as my starting point and adjust based on how things feel when I drive the car. Most cars aren't that picky. Cars like miata, boxster, 911 are usually the pickiest of the bunch (or maybe I notice more because of the way that I drive them)
