Schwalbe tires have a deserved reputation for toughness. When you are on a long trip with your Traveltrailer, the last thing you need is a flat tire on your 12" tire. The stock trailer tires we sell are good quality standard tires, well worth the price and durable. They aren't Schwalbe's though. When you want high quality tires that you can install and scoff at flats, this is the one to use.
Please note: installing just one tire is not recommended as a stock tire and a Schwalbe on the same trailer will cause an imbalance in height on the axles as the tires have different profiles.
