I've read many responses re: the best tire to use on the front, but have seen no advice re: what tires to use on the back of an GL 1800 trike. I'm about to convert my new 2015 GL 1800 using a HTS Roadsmith & would like some advice for the rear tires. I have decided to use the Avon Cobra 71 Trike tire on the front after viewing this forum. Thanks for any responses. I'm new to this forum but have already found it very informative & very helpful to someone new to the trike scene
