I have a tandem axle boat trailer which currently has four bias-ply tires
with disc brakes on the rear axle. The two tires on the brake axle are worn
and I am considering replacing them with Radials; I understand that you
never mix bias-ply and radials on the same axle, any reason that I should
not put radials on the back axle, and leave the bias-ply's on the forward
axle??

Thanks-
