Schwalbe Marathon GreenGuard Endurance Tire-Black Reflex, 700 x 32C

I have a 29" mountain bike that I mostly use for street riding these days. Because of this, I've been buying smoother tires but still like tires that are close to 2 inches wide. I selected the Schwalbe Marathon because of tread pattern and how I felt it would perform on asphalt that sometimes has fine sand on it (I live near the beach in FL so this is of particular concern). However I've never seen a tire size of "29 x 2/3". I found a reviewer who said he looked up the product number and it matched what I was seeking so I bought two of them even though I was doubtful the tires would be the right size. When the tires arrived, they were clearly labelled with the following sizes: "700 x 50c" (50-622)" as well as "50-622 28 x 2.00". I almost returned them straight away but decided to at least see how close they were to what I needed. As it turns out, they actually fit my 29" wheel! Both old and new tires bear the 50-622 text but the other sizes are clearly not the same. Evidently, I don't know enough about bike tire sizing... The width of the tire, when inflated, is exactly 1 7/8" (1.875") or 47.6mm. This is 1/8" narrower than my old tires but not so much that they look too thin to be on a mountain bike.Overall, and now that they're mounted, I really like the Marathons. They're smooth and fast-rolling and are easier to seat on the rim than my Surfas tires so they're much easier to balance. I've only gone on two 15-mile rides so far but I like them already. If they last, I'll keep buying these - time will tell.UPDATE: (Dec 2020 - after 8 months of use) These are my new favorite tires. They perform very well on wet, dry, and sandy roads as well as dry dirt trails. These are my new go-to tires!

Fauteuil roulant.

amazing good job

Rolling very nicely pumped them up quite firm, seeing me go much faster now

You cant go wrong they are super fast and not very heavy, fits my 29" Marlin 5 mountain bike rim perfect..
