Found a bunch of horsepower

I haven't been driving for about a month due to some medical issues. Couple of days ago the wife says "it feels like the brake is on". Got behind the wheel and I knew right away what it was.

Low tire pressure. The temps have gone down since the tires were put on and they lost 4 pounds each. A quick air up and she's a rocketship again, well as far as 4Runners go that is.

It's been my experience that just 4 pounds would not make that much of a difference, maybe it's just these Toyo AT3's are different as I usually run higher load rated tires than these SL's.

 

Hmmm...
Those are the tires I just had put on this summer. Once the temps around here really drop into the winter range, I'll double check them again. Especially if just 4 PSI makes that much difference with them.

Do you mind if I ask what pressures you normally run them at? I had the tire shop set them at 32 front, 34 rear. It's what I found worked best on my 87 4Runner, so I figured it'd be a good starting point. The tires have a good footprint at that. Entire width is on the pavement, but not less, not more.
It may cause some drag, but I was figuring on airing them down a bit for winter. More contact patch for the ice and snow we get here, would help traction some. Not mileage, or acceleration/speed, but in the snow, neither of those is of primary importance to us. We want GRIP!

Thanks for the heads-up, in any event!

Tire shop set them at 34, this all according to TPMS in the gauge cluster. They were down to 30.
I put them back up 33, because 34 on my tire gauge worked out to 33 in the TPMS screen.

 

Thanks!
