I thought about doing the same thing on my Volvo. Even when my steers are at 120 psi, they just look slightly flat, like they are low on air pressure. The other trucks that the company uses (Cascadias, Prostars, T680s) steers look "normal". I have my 5th wheel slid back far enough so that when I am loaded heavy, there is just under 12,000 pounds on the steers, so I know they are not over weight. I was thinking that maybe using a 16 ply tire would help "round" the tire a little. Help keep it's shape. Maybe get some better fuel mileage.

My last Volvo, a 780 was heavy as hell on the steers. My tires were wearing terribly on them, even after an alignment... But, looking back, I think it was the tire balancers I had installed. On the truck I own now, 2008 ProStar, I have the new Michelins and had them high speed balanced. I also religiously check the air pressure on them. No balancers, and no problems, again, knock on wood.

I couldn't keep steer tires on my 07 Volvo either. Come to find out it was because of the centramatics. Not that the centramatics were bad. It's was that the truck had the centrifused brake drums. Which are a lot thinner at the wheel mating surface. In which, that let the centrimatics go to far onto the hub, we're the hub had a larger diameter than the balancer was made for. So when the wheel went on it was put in a bind and was pushed way off center.
