More than just a summer tyre with incredible XP carcass protection, the SMART HYDRO tread compound makes it perfect for all four seasons. This hand-built XP series tyre combines a bead-to-bead reinforced Super Polyester carcass with SMARThydro tread compound, optimising traction on wet surfaces. The new Easy-Fit Shape moulding process gently preforms the tyre for easy fitting and inflation. Traditional vulcanised tyres cannot match its resistance to punctures and cuts, while offering low rolling resistance and fantastic ride quality: 4 SEASONS offers the best in all conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONSTRUCTION: Handmade\u003c\/strong\u003e\u003cbr\u003eChallenge handmade tyres combine comfort, performance and grip in a way that other tyres cannot match.
