The Race D is a replacement for Panaracer’s Duro and is billed as a four-season, ‘rock solid’ racing tyre. Puncture resistance is effective: there’s a robust breaker layer under the tread and bead-to-bead protection.
Panaracer claim that the casing construction resists pinch flats too The dual compound tread provides decent grip, wet or dry. The slight letdown is its rolling performance, which is good rather than great. It’s also tight fitting and quite a fight to get on the rim.
