Its not that much more pressure and I prefer the handling as well, the tires are certainly rated for it. In our "winter" I like to keep them a little lower, closer to the rating that's on the car door frame tire pressure sticker, not 36 psi cold as indicated but closer to 38 psi.39 psi is the most I have run in mine. Maybe need to pump them up a bit more. Don't you get a rougher ride with that much pressure?
