I have a 2019 100 long range AWD with the standard Continental Cross Contact 20" tire. By 20,000 miles the tires were showing significant wear on the front with very little wear on he back set. Since the front and back are asymmetric, the manual states not to rotate tires. I'm now at 26,000 miles and the fronts are evenly worn down to the point of badly needing to be replaced but the backs have probably another 10,000 miles to go. I'm moving to snow country in Feb for 3 months so want to get an all season tire but would like to identify the reason for the different wear pattern before I lay out the money for more tires. There are no signs of an alignment problem ie the wear across each front tire is even, there is no shimmy or pull. Half my miles are on highway and half on country roads, some of which are admittedly rough. I use the break as little as possible and am definitely not a rocket jockey. Is it the tires, the car design or the way I drive?
