Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A used car lot has 24 cars and motorcycles (in total) for sale. A third of the vehicles are motorcycles, and a quarter of the cars have a spare tire included. How many tires are on the used car lot’s vehicles in all?

### Response:
The used car lot has 24 / 3 = <<24/3=8>>8 motorcycles with 2 tires each.
The lot has 24 - 8 = <<24-8=16>>16 cars for sale
There are 16 / 4 = 4 cars with a spare tire with 5 tires each.
The lot has 16 - 4 = <<16-4=12>>12 cars with 4 tires each.
Thus, the used car lot’s vehicles have 12 * 4 + 4 * 5 + 8 * 2 = 48 + 20 + 16 = <<12*4+4*5+8*2=84>>84 tires in all.
