I thought bias referenced the tire's design (sport, touring, cruising, etc.)

front tires are designed differently then rear due to the forces they endure; most of the weight is on the rear tire while riding; while the front needs to be reinforced to support the bike under braking.

I wouldn't change bias front/rear for riding type, the ride will suffer performance.

Mixing bias ply and radial tires on your cage is bad news. They tend to walk around and the vehicle is unstable. I had it happen on an old GMC Jimmy full size and it isn't a good feeling. I don't know about a bike though.

no. bias ply is an older method of constructing tires in which the belts are ran down the center of the tire, parallel to the beads. they are suceptible to expansion when accelerating and travelling at high speeds, have lower side wall strength and generally operate at a lower temperature than radial tires. radial tires belts are arranged perpendicular to the beads.

i've mixed bias rears with radial fronts, and was fine, but the setup isn't ideal and isn't recommended by any tire or bike manufacturer.

why aren't you changing the front as well? performance will be signifigantly better with matching radials on both ends.

I misread; didn't read the title so I was basing my information on differences between manufactoring of front and rear tires
