I DO NOT want to "upgrade" to a 15" rim and low profile tire. The roads around here are beyond terrible and don't want to chance a bent rim.

I ran this tire on my old flatbottom with good luck and it pulled like a dream on it. Tire was super stiff and always had a feeling it would do great on a heavier trailer. That said, I'm casually shopping for a new wheel/tire combo for my Tracker 175txw trailer. Tire diameter is 24.4" and looks to be about maxed out so going bigger isn't an option. The OEM Loadstar Carrier tires are soft and bounce around like crazy even with 50psi. I could be wrong but I think the K550 is way stiffer and would track better on these torn up curvy roads around here. I know a guy who sweared by bias ply tires on his old Winnebago because they tracked better and didn't drift like radials on that big heavy beast. They drove the hell out of that thing between Arkansas and Quebec every year.
Basically, I'm looking for suggestions on a super stiff tire. Total weight is roughly 2000lbs loaded to fish. I tend to stay within 30-45mins from the house and most of that water is 100% state highway (55mph) between here and there.
