Schwalbe Marathon Plus 700×35C Tire

Product Overview

The Schwalbe Marathon Plus is a maximum puncture-resistant touring tire featuring a 5mm SmartGuard protection layer that makes bicycles virtually flat-proof. Designed for 700C wheels with 35mm width (37-622), this tube-type tire combines exceptional puncture protection with low rolling resistance, anti-aging sidewalls, and E-bike compatibility up to 50 km/h. Schwalbe's best-selling model for commuters, tourers, and riders prioritizing reliability over weight.

Key Features

• 5mm SmartGuard puncture protection layer – Patented extra-thick protective belt stops thumbtacks, glass, thorns, and road debris from penetrating the tire casing
• Virtually flat-proof performance – Industry-leading puncture resistance makes flats extremely rare even in harsh urban or touring conditions
• Low rolling resistance SmartGuard design – Despite thick protection layer, optimized compound and construction minimize rolling resistance compared to generic puncture-resistant tires
• Endurance compound – Durable rubber formulation maximizes tread life and wear resistance for extended mileage
• Anti-aging sidewalls – Sidewall treatment prevents cracking and degradation even when ridden at lower pressures or stored long-term
• E-bike ready (E-25 rated) – Approved and tested for electric bikes up to 50 km/h (31 mph); handles higher speeds and motor-assisted loads
• Recycled rubber content – SmartGuard layer incorporates recycled latex from old products for environmental sustainability
• Reflective sidewall stripe – Built-in reflective band increases visibility in low-light conditions

Compatibility and Ideal Use Cases

This tire fits 700C (622mm BSD) rims and requires a 37mm (or 35-43mm range) inner tube. The wire bead design is not tubeless-compatible—requires traditional inner tubes for operation. The 35mm (37-622 ETRTO) width fits most road, touring, gravel, hybrid, and commuter bikes with adequate frame and fork clearance—verify your bike accommodates at least 38mm tire width to allow proper clearance for the tire plus debris. Ideal for daily commuters riding through urban environments with glass and debris, long-distance tourists who cannot afford flats in remote locations, cargo bike riders carrying heavy loads, and E-bike users requiring robust tires for motor-assisted speeds and loads. The Marathon Plus excels in situations where reliability trumps weight—the thick SmartGuard layer and durable construction add approximately 200-300 grams per tire compared to lightweight alternatives. Best suited for riders who prioritize puncture protection and longevity over speed and weight savings. The anti-aging sidewalls make these excellent for bikes that sit unused for extended periods or are ridden infrequently. Not recommended for competitive road cycling, racing, or applications where minimal weight and maximum speed matter—the added protection increases rolling weight and reduces acceleration compared to race tires. The E-25 rating and ECE-R75 certification make these particularly suitable for Class 1, 2, and 3 E-bikes in North America and speed pedelecs in Europe.
