The 24 x 1.75 Marathon Plus (507) tire by Schwalbe is a highly puncture resistant tire with a high load rating. It fits juvenile mountain bikes, Schwinn S-2 size and cruisers. This tire has a 5mm thick SmartGuard layer that resists shard of glass and flints.
Punctures become obsolete with the MARATHON PLUS! The SmartGuard layer made from a flexible, special rubber offers particular resistance to shards of glass and flints. Even a thumbtack cannot penetrate this protective layer. The SmartGuard belt does not increase rolling resistance. The MARATHON PLUS rolls as easily as a tire without protection.
Schwalbe Marathon Plus Fact Sheet and Reviews
From EBTire: The Schwalbe
Marathon Plus is truly the type of tire you need if you
just can't have any flats. We see a lot of tires but
this is the thickest one we sell. It has the same casing
as the Marathon Regular giving it the same traction and
the same feel. The casing of the Marathon Plus has a
real thick strip of material built into it so it can
stop small objects. It also has a high weight rating so
it is the kind of tire the heavier rider should look at
or those who use powered bikes. Visibly thicker and
studier feeling than other tires, these tires are worth
their weight in gold for reliability and safety. Highly

The original. The archetypal high quality touring tire. Now completely revised:
GreenGuard. The highly elastic, India rubber layer is 3 mm thick. Other manufacturers call such a tire “Plus”. However, Green is not just the colour, but also the philosophy: One third of the GreenGuard is made up of recycled latex products.
"Anti-Aging". The completely new sidewall construction can withstand for much longer the typical cracking resulting from overloading due to insufficient inflation pressure. Also the new Endurance Compound substantially increases durability.
E-Bike Ready. The new Marathon has been designed for use on all types of E-bikes. The following sizes bear the ECE75 mark, suitable for use on faster, up to 50 kph, E-bikes.
