I drive my 1-ton pickup 100's of miles a year (not thousands
) on bias plys. Given a choice, I would naturally prefer radials (who wouldn't?) but so far, I have no complaint with my bias ply 17's. And with my 261 and 4.10 gearing, I am comfortable running 65-70 MPH all day long.
In my experience, radials are preferred, but bias plays get the job done, too, if you know how to drive a truck ...
If you only are familiar with little euro/asian car sedans with 4-wheel disc brakes and automatic transmissions, then by all means, stick to the radials.
