I bought this bike (2001 FLHRI) with already custom 18" wheels front and back My questions are as follows (answer any or all that you can). 1. What size tire (max width)can fit on a 2001 Road King with 18" wheels and stock fenders? Currently I'm 130/70-18. 2. I'm having problems finding the same kind of tire that will fit for Front labeled tires and for Rear labeled tire. Can I use a front tire on the rear also since more front tires are available in 130/70-18? 3. It has Avon AM23 front and rear (they are mounted in opposite directions as it recommends on sidewall) with good tred put cracked up sidewalls from just sitting around for years. Does anyone have experience with AM23's and love or hate them? 4. Tire recomendations for front and rear 18" wheels?
