This is "Off Topic" but not "Just for Fun"...
Main Questions:
(1) Which type tire is better for a dually truck which carries a load, bias ply or radial?
(2) Are there narrower dually rims that would provide less clearance than standard dually rims?
Details:
I have a 1974 Ford F350 Dually flatbed truck with 7.50x16 bias ply tires that I haul my tractor on. The wheels are not split rims. With the tires filled with the maximum 60 psi pressure, they have about a ¼” clearance between tires when there is no load and they touch each other (usually they barely touch) when my tractor is on the truck.
Additionally, the tires are showing signs of dry rot and leaking from the sidewall.
So, it is time for new tires. But when I get these new tires I want to cure the “tire touching” problem at the same time. I’m convinced that simply buying new 7.5x16 tires will cure the dry rot problem but not the touching problem. Buying new (standard?) rims should cure the problem, assuming that I somehow have some type of narrow rim.
Regarding tires, this is what I have been told so far by various experts(?), and items 3 and 4 disagree with one another. I would like to get a reality check on the information:
(1) 235-85-16 radial tires are the same height as 7.50x16 bias ply tires but are slightly wider, which would make my tire touching problem worse.
(2) 215-85-16 tires are narrower than 7.50x16 bias ply but are also not as tall
(3) Radial tires have a softer sidewall and aren’t as good as bias ply tires for load carrying applications
(4) Radial tires are better than bias ply tires for load carrying applications.
Thanks for any information,
Kelvin
