Need snow tires for my 2015 Toyota Highlander Limited
I have 245/55R19 tires on the vehicle now but need snow tires. Toyota says that I can use 18 inch tires but they are very expensive. They also say that I must buy the 18 inch alloy rims as they do not com in standard black ($$$). A reputable local tire dealer is selling a winter tire package for Toyotas and for the Highlander, they say I can use 17 inch tires. Is this true.
