Any recomendations for a rear tire make and size to use on the front? I have a new E3 radial on the back now and a getting worn E3 on the front. I am not pleased with the E3 front, it had an out of round condition from new and I want to replace it. Can I use a 130/17 instead of a 150/17 on the front?
search is your friend, don't be afraid.

I use a Contigo rear on the front with an E3 on the rear.
