Light Truck 215/85R16

The recommended rim width is wider than our original wheels/rims, but mounting that side radial on a 4.5" rim will make the tire taller (lowers RPM) and narrower (makes the tires look more "natural" for the old truck).

Some people argue that mounting on a narrower rim puts strains on the sidewalls. That might be true for Le Mans racing, but no one has posted experiencing side-wall failure.

One pair on my trucks are 12 years old - well beyond the "warranty" period.
