These were installed on a new, stock Corolla LE, on Sport Edition alloys, purchased mounted and balanced from Tire Rack. They were Plus 1 size vs. the OE tires and steel wheels. This size is an option on the Corolla. The difference between these Continentals and the OE Continental all-season touring tires is unbelievable. Yes, they are a bit more harsh, and slightly noisier, but I estimate that these tires work better in the wet than the OE tires do in the dry. My only complaint is a pronounced low-speed (20 mph) growl when coming to a stop. Of course, they are completely unsafe for winter use, but I purchased a set of Michelin Ice winter tires for the OE wheels. As you can tell, I'm not a fan of all-season tires, which I feel are a very poor compromise. These tires do not turn a Corolla into a sports car, but I'm now very comfortable driving the car with these tires in all types of three-season conditions.
