  • Wheels / Tires: Best radial match for 6.50-16 LT tire is...?

    Hi again Guys,


    What is the 'best'/ recommended radial tire size match for a 6.50 - 16 LT tire? I understand that changing to a radial tire will help smooth out the ride. I've already replaced the shocks and some front end parts. Thanks for your replies.

    Hi Mark.
    I think the size of a 6.50x16 is 6.5" width and 80% aspect ratio of 5.2"giving an overall diameter of 26.4". The metric size would be 165/80x16. I don't know if you can get them but 175/75/16 may be a better choice? I can't help but think a radial will have a smaller looking sidewall than an old crossply??? I'm not a tyre expert so hopefully someone else will be around to help
    The funniest thing about this signature is by the time you realise it says nothing important, it's too late to stop reading it.

      I put 195/75/16s on my Champ truck. They are just right. Fit right on my original rims.

        Just measure the Diameter of your current Tires and get the Radial that most closely matches.
        Then you will have the best "Look" and closest Speedometer reading.

          Assuming the current tires are correct.
          The ones I put on my truck most closely matched the size/dimensions of the tires that came on the truck originally. The ones I replaced were not even close.

            I ran my '57 1/2 ton Transtar on 215/85R16 for 11 years with no issues. Stock truck 16" (5x5) 1/2 ton rims were used. No clearance issues and a vastly improved ride. Steering was not an issue either except at very slow speeds making tight turns in parking lots - it still did okay, just a bit of arm twisting!

            PS - It was easy to change the pinion gear in the 3 spd OD transmission to get an accurate speedo reading.

              I am sure Mark can read the Tire size on the tires on the Truck, and see if it matches the Factory correct size in the Parts Catalog, Production Order, or Truck Brochure etc.

                If only Mark had Parts Catalog, Production Order, or Truck Brochure etc... ;-)

                  X2 on the 215/85-16 being a good choice. I've run them on my E12 for thirty plus years. Yes, they do increase steering effort when stopped, so just don't do that. Always begin forward or reverse motion before turning the steering wheel.
