You can find a decent set of used tires on CL for $350 easy.
I just bought some for my 4Runner, 285/75-16's with 80% tread left for $250
I wouldnt run recaps on a DD.
I guess the quality is better now than years ago.
A quality recap would probably be better than a new chinese tire though.
I ran recaps on my cars in the early 80;s when I was a teenager, but I had my OWN tires recapped, that way I knew the history of the casing.
Plus with a 375 HP engine I burned off the tread pretty quickly.
I've owned six 18 wheelers, and I never bought recaps, they almost always come apart.
every single truck tire tread (interstate alligator) you see on the road is a recap that came apart, and most likely caused some or a lot of damage to the rig when it blew.
