Hi Randy..
Yes, the tires do sway a bit from side-side when going over speed bumps and the like. But I am very happy with them and their long-life performance. <<
I"m looking for radials... never noticed any swaying when I towed, even over the Tennessee mountains (nothing like yours, though). The tires that I got with Stargazer still have a lot of tread on them, but I'd say that they're at least 10 years (or more) old!! No sidewall cracks, but there's a slow leak in one, and the spare is a bias ply. Methinks I'll get a pair of radial trailer tires and use the good tire as the spare. I'm having eye problems, an dwhen the day comes for her to go to another sailor, I'd like to have a decent set of tires on her... Harvey/Ga M-17 Stargazer #294
