The treadwear rating is 360, the same as the OEM tires. They should last about as long as the OEM tires did.

I am not tire expert...
But I think even the tread wear is 360... 15,16,17,18,19 inches does make different
H, W, Z rated tires also make difference even they are same tread wear
How wide of the tire will also make difference too
Temperature will make difference as well

Your car condition will also make difference
When your car is lowered, tire wear from inside cause of the off camber
And it will cut down your tire life
So your tires might look brand new outside but inside is all flat

You cannot compare the wear of the tire with your stock tires
Unless they are the same exact tires
