Scott, this is hilarious! I love it. Sometimes a man's got to do what a man's go to do.

This is basically what I do. The original tires on my TV ran at lower pressure to get the max load -- 32 psi. But to get around that same load on my new Michelin LTX M/S 2 tires, I've got to put in close to the max pressure of 44 psi, which is what I tow with. While towing, the ride is much improved with the higher pressure, but riding around town it's a noticeably stiffer ride. I have been riding with about 42 psi, and that didn't make much difference from 44. I may drop down to 40 psi, but I'm not expecting much of a softer ride.

It's likely that their initial response, at least, will be, "we recommend you ride on tires filled to the maximum rated pressure." That's the response I got from Kumho, until I got an engineer on the phone. He in turn sent me an Excel spreadsheet (which I have posted here on the forum) that shows load ratings at various pressures below the max. Frankly, it looked like he probably made it up in 5 min after getting off the phone, but I relied on it and it worked well (umm, at least until the blowouts during a heat wave when the tires were 3 yrs old).
