The specs. say that it has a 31.8 inch diameter! If anyone has used these tires, how do they fit? Any rubbing in the turns?

That would most likely be no problem (I am running tires with about that diameter). What wheels would you be using? | | | | | Joined: Jul 2005 Posts: 21 New Guy | | New Guy Joined: Jul 2005 Posts: 21 | I like the large diameter look and higher top end speed (4.11 rear)but was concerned that they may not fit. I am using early 1960's OEM 16" diameter, 5" ID width wheels that still have the hubcap clips.
What radial tire are you using that allow for the use of innertubes? | | | | | Joined: Sep 2001 Posts: 29,270 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,270 |
As has been recently posted, most radial tire manufacturers do not recommend the use of tubes in tubeless radial tires. Six years ago, I was lucky enough to find a dealer who was willing to install tubes in my original 6.50x15 wheels. I guess he figured that the speeds and distances the truck would travel was not significantly risky.
The next pair I have installed will be tubeless on original wheels that are in excellent shape.

If you are well under the load rating as well, you are very unlikely to have any problems. Assuming you use new, high-quality tubes, and carefully inspect the rim where they contact the tubes, plain old common sense sez: no worries.
Unfortunately for Americans, product liability concerns always trump common sense. | | |
