Using your Schwalbe Marathon Plus tire is easy. Just install it on your bike according to the standard tire - mounting process. Make sure to check the air pressure regularly, as the sidewall is more durable but still performs best at the right pressure. For E - bikes, since this tire is designed for speeds up to 50 km/h, always ride within this speed limit. When it comes to maintenance, keep the tire clean. You can wash it with mild soap and water. If you notice any signs of wear or damage, like cuts or excessive tread wear, it's time to consider replacing the tire. And remember, don't forget to recycle your old tire to keep the environment clean.
