Tires: tires 93V and 94H, load index, tirerack com

Question
should I buy a 93V which is about $30 per tire more or a 94H? I am not sure of the difference

Answer
Bruce,

The numbers and letters are called a "Service Description" and that consists of a "Speed Rating" (the letter) and a "Load Index" (the numbers).  You don't need to know a lot about this except to say that if you are trying to select between tires of the same size with these 2 Service Descriptions, then the major difference is the Speed Rating - V is higher than H.  What generally comes along with that is that higher speed rated tires TEND to be (but not always) harsher riding, but with better steering response (the are tradeoffs!)  Higher speed rated tires also TEND to have (but not always) better grip and worse treadwear (these are also tradeoffs!)

If you want to know more, Tire Rack has done about as good a job of explaining this as I have seen:
