That is true! Actually, two trim levels (LE & GT) come standard with 175/55-15 tires (22.6" OTD) in 2019.
Thus, someone would have to argue 175/65-14 tires (23" OTD) are trashing your transmission. A higher profile tire probably has slightly more weight, but it can't be that much? It comes down to more rim less tire vs. less rim more tire. I think the argument would be total BS, too.
Steve has 240,000+ miles on his Mirage, & he uses 175/65-14 tires. Then again, he drives a manual.
