Treadwear rating on that tire is only (140)...must be a very soft compound.
So your tires are gonna wear pretty fast.
Normal driving & an average way to calculate milage/per treadwear rating....is to add 2-0's to the backside of the treadwear #.
so a 140 would yield about 14,000mi...300-30,000mi./driving habit's play a huge roll.
get some all season tires (500 or so treadwear) & keep your foot out
of it & get close to 50k.
This is only from personal experience & knowledge gained from myself,close friends & family + years of mechanic work...so don't shoot! you probably won't see this posted anywhere;as cars weigh different amounts,fwd,rwd,awd,etc....all are determining factor's.
It just gives you a baseline to go by.
