Some of the posters nailed it right on the head....with sway control you do not get TT wag. A good wind will move both TV and TT as one. I have experienced this and its correctable with a little steering input. I put new tires on TV. They are still P metric but are T rated and handle about 200lbs more weight per tire than the stockers. I also keep them at 40PSI. I could go higher if needed. TT tires are inflated to max pressure also. Equali Zer is noisy. I did buy the plastic type pads that go under the bars to help with creak noise.
