Thanks Terry & Rob,
I need to clarify that my unit is a 27 foot Argosy MOTORHOME, not an Airstream trailer. The tires are 8 x 19.5, which I think converts to a 8R19.5 for the radial. I am getting prices of $180.00 to $220 per tire, which seems pretty high. I don't yet know if they are tubelesss, but I suspect that they were in 1976.
Dopes anyone know if the Univolt units are avaialbel new, and where to get them and how much they cost?
Chas, the univolt is available as an updated version, all electronic (no hum). There are several sources online for them, just be aware that even though they are electronic, they are still quite heavy for shipping.
If your tires are 19.5, they should be tubeless, and there is no good reason not to go with the radials.
One thing to be aware of, is that no matter what tire makers say, try to keep them rotating the same direction on the MH. On some radials, if you have a tire, say, on the left front, and put it on the right front, the belts my shift, causing tread separation or a very bad wobble.
People will tell you this is an old wives' tale, but IT IS NOT.
Two identical cars, with the exact same tires, one belonging to my son, the other to me, both with the same mileage on the cars, he rotated his tires in a "criss-cross" pattern, reversing direction of rotation, I didn't. After 15,000 miles, he had replaced three of his tires due to belt shifting, I had the same set.
Other than that, replace with a good set, with the same or higher load range (should be D or E).
You will probably be surprised at how good your MH rides with the radials.
