The Schwalbe Marathon Tires incorporate light-reflecting sidewalls for better visibility and also utilizes a Silica compound for easy rolling and longer life. It's the most puncture-resistant pneumatic tire on the market. The Marathon Plus is the only tire worldwide that can be called "flat-less". This is due to its unique and patented puncture protection belt: five millimeters thick and made from highly elastic special rubber. Even thumbtacks can't puncture it!
My cycling partner and I rode the length of the Northern Tier Route with these tires and had one flat between us the entire way, and that was a tube valve stem issue at the very end of the trip. Highly recommended!
Good all around tire

Bought these to replace the stock tires on my touring bike. Unfortunately, there is not much touring in a time of pandemic so I’ve been testing them on the mean streets of Albuquerque and one off road (gravel) ride. So far, they’ve performed admirably and have more traction than my tried and true Continental Gatorskins. They are a bit heavier (700x28), but provide lots of stability and confidence when zipping downhill or cornering. Looking forward to the day when I can put them to a multi-day ride test!

My rear tire has 5000+ miles and the front tire has 6000+ miles. I've used it for local training and for riding the Western Express and the Southern Tier as well as a couple of RAGBRAI's. Zero flats. Can't say enough good about these tires!

We road across the country plus other rides later. No flats. The tires are 5 years old and I just replaced them. Great tires!
3 years - ZERO flats

Have used for loaded touring both loaded and pulling and commuting daily in temps ranging from 15-106 F riding on mainly paved roads and some hard packed gravel roads. Zero flats, had to tighten a valve stem once, but that wasn’t the tire’s fault. Heavier, sure, but I’m happy pulling a few extra grams instead of pulling to the side to repair.
