Wheel widths matter more if you choose the relatively stiff carcass drag radial. Slicks you can get by on a narrower rim, as long as you are prepared to pressure down to get them to sit flat. I have a true 10 inch wide tire on a 7.5 inch rim out back.
I have used both repeatedly. What has been said above is true. Dr auto, slick mt. Slicks need to be flown all the way down track, particularly with radials up front. Drs are better suited to rookies at this
