I put Ride-On in all 3 tires...LOVE it....on a good road, at 70mph I can turn loose of the handlebars, clap my hands above my head, stretch my shoulders, and this trike goes straight down the road until it meets an anomoly in the road taking it on a not-so-straight path.
I put R-O in originally as I wanted less chance of a flat tire...the balance was icing on the cake...I don’t have lead weights on the tires.
This has been MY experience on my GL1800. There are others here on TrikeTalk who ride other brands of trikes that can’t say enough bad about the product... but that’s their experience.
