...all have red lines on the tires.? Does the hot wheels line only carry the collectors red line on the tires or do the rest of the diecast company's also do it too?

hot wheels cars that you are talking about are a symbol that hot wheels used between 1968 and 1977 and belive it or not they call the car colletion "Redlines" i havent seen any other company do that on there cars. if you search on line, the only car company that comes up with redlines is hot wheels.

I collect Maisto and I can tell you they don't do that.
