RepairPal Expert Overview:
Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle.

2012 Toyota Prius Reviews
I love my Prius, But at 400 miles as I was driving home I began to hear a loud hissing sound coming from the back passenger side seat, where the vent is for the battery. It was not there for the first month and is loud after driving for a while. I took it to Desert Toyota to have it checked out and explained that is takes awhile for the noise to become loud. They never really checked it out and just told me it was normal, so why didn't it happen the first month I had it, and why is it loud enough to hear even when the radio is on. Not happy with the dealer, wish I could redo the survey!
