I have the Hercules H-902's on the coach, I notice a few times if the right front catches the edge of the pavement it doesn't want to get back over it easily.

These tires have a very square edge.

Someone mentioned that if I had steer tires on the fronts it wouldn't happen.
He said that Firestone FS560+, are specifically made as steer tires

Any opinions

Stay between the lines? Not being a smart *** but if you're running off the right enough that you're considering changing tires to get back on the pavement are you also crossing the center line that much? These are big vehicles to be wandering around the road.

Do you really think that was a helpful reply

Absolutely. I told you I wasn't trying to be smart. You could have anything from bad steering components to weight distribution problems to not knowing exactly where you're at in the lane. Have you tried to hold it in exactly the same spot in the lane for a distance to see if the vehicle moves around and you constantly have to correct?

I recently changed to six Firestone FS560 tires and no they are not steer tires. They are truck tires rated for local delivery, short trips (vs. over the road tires traveling a gazillion miles a week). The FS560 work well up front. They have a stiffer sidewall than an RV rated tire which gives you crisper steering response. Also, the sidewalls are more resistant to curb scuffing. I am pleased with my choice of tires.

Problems with dropping off the edge of a road surface are more likely helped by aftermarket steering modifications than changing tires.

Hercules says that tire is all position so it "should" be okay for steer.
I think the force necessary to bring the tire back on the pavement has more to do with the drop-off of the pavement than the shape of the tire tread.
Of course I have never driven off the edge of the pavement so I don't have any experience in this matter.

That being said, all my vehicles tend to climb the ruts in the highways around here, wider the tire the worse it is
