Tires: Tire load ratings, slight difference, 94v

Question
What is the difference in a tire rated at 93V and 94V?
Thanks

Answer
Terry,

I'm going to make an assumption that both tires are the same size - that is, all the numbers are the same in the same order, like this:  P215/60R16 vs 215/60R16.  Notice that one of the sizes has a "P" in front of the tire size.  That means it is designed to a US tire standard, where the one without the "P" may be designed to a European or Japanese tire standard.

If that is true, then there is a slight difference in the way in which the tire standards are written that results in a slight difference in the way load carrying capacity is expressed - and for practical purposes, those tires are interchangeable.

I cover that in more detail here:
