My 3500 Dodge Diesel Scotty Motor Home is getting new tires tomorrow 215/85R16 MIC M/S2 LTX I am replacing all 6 of them. Also getting metal valve stems all this for $1450. out the door. My buddy wants my old tires so that will save me a little money. That the best deal I could find. My old tires are 2004 which makes them 11 years old. They still look good but time to replace them. Should not go over 7 years I have been told. I only have 62,000 miles on the Dodge. It still looks new.
