Will a steering stabilizer help?

[custom10nut]

Like the title says, will putting a steering stabilizer help to tighten up my steering?
I run wide tires on the front (275/60/15) and even after getting my front end aligned, it wants to wander. (Though not nearly as bad as be pre-alignment)
It's usually from irregularities in the road.
I'm thinking the big tires are just catching everything out there.
I put a stabilizer on my Jeep, when I mounted larger mud tires on it and it helped, so I was wondering if one would do the same on the truck.
Is anyone out there using one?
