2017 Lariat F-350
 

I have a 2017 F-350 Super Crew Lariat 4X4 single rear wheels & a 2019.
As far as I can tell, the wheel dimensions are the same, but the tires on the 2017 are 275/65R18 & the tires on the 2019 are 275/70R18, which look better. I was wondering why Ford went to a bigger diameter tire & if it won't hurt anything to put the bigger tires on the 2017?
