"Challenge calls this its most versatile handmade tire to date - a tubeless-ready (H-TLR) model that can take the #@$% weather and road conditions. Stagioni means seasons in Italian, and this tire should be good for all 4 Stagioni. The 4 Stagioni XP features a 260 TPI SuperPoly casing and full-coverage Corazza Silver + Gold Armor (the same that you'd see in the Challenge gravel lineup), which wraps the casing bead-to-bead for better puncture resistance and sidewall durability."
"Before the launch of the updated Challenge tire line, the Italian powerhouses' road line was skewed toward performance only. Now, thats not a bad thing at all, especially if you like going fast. But the catalog had a lot of holes; it was lacking a true endurace, super cut-resistant road/all-road tire, a budget-friendly, voluminous road tire, and a needed general modern sizing refresh."
"Challenge Tires updated its road offerings for 2026, taking some of the tech they learned from their gravel tires (like the Gravine and the Getaway XP) and opening up a new endurace range. The 2026 offerings include three major road-tire additions: the all-new 4 Stagioni XP, the reworked Strada Pro, and the more accessible road-race Elite Pro. We've had some time to get to know the new tire line and have some impressions, but let's discuss how we got here."
Challenge Tires expanded its 2026 road lineup with three new models: 4 Stagioni XP, a reworked Strada Pro, and the more accessible Elite Pro, adding an endurance-focused range. The update transfers technology from gravel models to road tires to improve puncture protection, sidewall durability, and wet-weather traction. The 4 Stagioni XP is tubeless-ready with a 260 TPI SuperPoly casing, full-coverage Corazza Silver + Gold Armor, and a SMARTHYDRO compound for better wet traction. Existing models like the Criterium RS, Strada Bianca, and Strada OG remain, preserving a near-tubular ride feel while addressing sizing and budget gaps.
