Well, as I was unable to get the information...my 70 year old father has been a great help once again. He was not able to find the tire information on the "passenger side" tires, so he climbed under the slide out on the "drivers side" and retrieved the following information: Radial Ultra CRT ST235/85 R 16. It also stated that the tread surface was 2 polyester and 2 steel ply, and the sidewall was 2 polyester.
Having learned this information, I now have possibly two choices in tires...both being Goodyear...the Marathon which is denoted as an ST tire and carries a load range of E, and the G614RST which has a load range of G and according to Goodyear is rated for heavy Fivers and TT's. But first must touch base with CC about the rims, as I have information on most everything else.
