The 380/150-5 tires are bigger, so likely they would make your problem worse.
The 380/150-5 tires are about a half inch wider, and an inch bigger in diameter if I recall correctly (and I may well not!) I had to open up the opening in my wheel pants pretty significantly when I switched from the standard 500-5.
You should be able to get your thumb in between the tire and the wheel pant edge all the way around with the airplane weight on the tire. If you can't, please fix that before something worse than the smell of rubber burning happens.
We like the larger tire for operations on dirt and grass. For paved runways, the standard tires are perfectly fine. As I mentioned in the first reply post, you have to position the wheel pant higher to allow room for the larger diameter. I found that this caused minor interference with the brake caliper, so I made a fiberglass fairing around the cutout that was required for brake clearance. It is a very modest little bulge. I still have the mold for those fairings, if anyone would like to have a couple of fairings, I can whip them out pretty quick. I would just charge a few bucks to cover the epoxy and glass material, and shipping.
