The 31 is the overall diameter so it will be 31" tall, the 10.50 with the the width 10.5" wide, x15 will be the rim size.
31 means that the tire is 31" tall, the 10.5 means that the tire is 10.5" wide and the 15 means that it fits a 15" rim.
31% of 105= 31% * 105= 0.31 * 105= 32.55
Max tire size with stock suspension is 31"
15 inch sould be the stock rims and 31 should be the norm for the tire size
my s10 is 15 inches for the rim and 31 for the tire but all cars very between the rim size and the tire size
Thought it was 31 1/2
