Does anyone know where I can get replacement tires at a reasonable price for my 1979 Mercedes 6.9 litre? I am told that Michelin doesn't make them anymore, and that the only place is Coker. The price from Coker is crazy.

I wish I had an answer for you. Does any regular tire manufacturer sell 70-series tires any more?

Edit: I found this chart and plugged in 205/70-14 and got a few hits: http://www.performanceplustire.com/products/tires#prodAnchor
