usually slower when towing, if due only to the limited power, and often necessarily due to stability limitations. On the other hand, if it is okay to use lousy tires on the trailer, it follows that people who just drive slowly should save their money and use lousy tires, too.
Someone should tell those big rig drivers that trailers drive gently - I'm often not willing to push just our van (no trailer) hard enough to keep up with them through the curves at the bottom of valleys on BC mountain roads.
