Its tread pattern provides low rolling resistance on tarmac while the shoulder knobs deliver grip on gravel, dirt, and light trail. It is particularly well-suited to e-MTB, trekking, and commuting with occasional off-road detours.What does "E-25" mean on this tyre?E-Bike Ready 25 (E-25) is Schwalbe's certification for tyres designed for standard Pedelecs — e-bikes with pedal assistance up to 25 km/h. These tyres are built to handle the higher loads, increased torque, and greater wear caused by motor assistance. The E-25 rating is the most common e-bike tyre standard in Europe and is suitable for the vast majority of e-bikes on the market.What is the difference between E-25 and E-50 certification?E-25 tyres are rated for standard Pedelecs (up to 25 km/h, no special registration required). E-50 tyres carry the ECE-R75 type approval and are required for fast e-bikes (S-Pedelecs) travelling up to 50 km/h, which require insurance and registration in most European countries. For a standard e-bike or e-MTB, E-25 is the correct and sufficient certification.What is Addix Performance Compound?Addix Performance is Schwalbe's universal rubber compound for the Performance Line. It offers a wide operating range — balancing grip, rolling resistance, and durability across varied conditions and temperatures. Similar to Speedgrip in its versatility, it is the ideal compound for riders who encounter mixed surfaces and weather. It is more durable than Addix Soft (which prioritises grip) and grippier than Addix Race (which prioritises speed).Is this a tubeless-ready tyre?No. The Smart Sam HS 624 in this listing is a wire bead (clincher) tyre that requires a standard inner tube. Wire bead tyres are heavier than folding bead tyres but are more affordable and very robust. A folding or tubeless-ready version may be available separately — check the product code carefully when ordering.What is the maximum tyre pressure for the Smart Sam HS 624?The maximum pressure is 3.0 bar (44 PSI). For a 2.60" wide tyre, typical riding pressures are 1.5–2.5 bar (22–36 PSI) depending on terrain, rider weight, and preference. Lower pressures improve grip and comfort on trails; higher pressures reduce rolling resistance on tarmac. Never exceed the maximum pressure marked on the tyre sidewall.What rim size does this tyre fit?The Smart Sam HS 624 (65-584) fits 27.5" rims (also known as 650B, ETRTO inner diameter 584 mm). It is not compatible with 26", 29", or 700c rims. Always verify your rim's ETRTO diameter before purchasing.Is this tyre suitable for a heavy e-MTB?Yes. The Smart Sam HS 624 is specifically optimised for e-MTB use. Its reinforced construction and Addix Performance compound are designed to handle the additional weight and torque of motor-assisted bikes. The E-25 certification confirms it meets the safety and durability standards required for Pedelec use.When will this tyre be available?This tyre is available from Week 41/2026 (from 05.10.2026). You can pre-order now to secure your allocation. Orders will be fulfilled from the availability date.Is this tyre sold individually?Yes, this listing is for one (1) tyre.
