The 2020 Sorento LX AWD I purchased a month and a half ago replaced a 2014 Jeep Patriot 4WD. That Jeep could go anywhere...until there was a 1/4 inch of snow on the ground. I could barely keep it on the road. I had to stay far behind the car in front of me to keep from rear ending them. Until I got dedicated winter tires. It was like a different car. Or like driving on dry summer roads. So I know how much of a difference winter tires make. Rather than wait to see how the oem tires on the Sorento handle snow and ice, I decided to go ahead and order me some good winter tires. I always get my tires from Tire Rack (I live close enough that I go to their facility and have them install them). I went on their website and saw that our vehicles came with 235/65R17 tires. Found some nice Michelin’s and placed an order, to be installed later in the week. Was tinkering with the car today and double checked the tire size. Good thing I did! My car has 235/60R18. I bought it used, but it only had 2,000 miles on it, so it had to come from the factory with these. I checked a couple other sites and they all said the standard size was 235/65R17. Was the larger size an option?
