Ironman tires

Ya know when tires last "only 5 years" nowadays, you wont wear them out on your hobby car. Buy cheap. I'll start looking for those shipped to the house. I'll mount myself with tubes so the old *** Centerlines wont leak out on me. The valve hole is corroded slightly on both so I dont know if they will seal there either, tube it! Then take 'em in for balancing. Do they make them in 70 series? I need taller rather than wider on my lipped 65.
