Road tyre Continental Grand Prix 4-Season 28" — 22-622 (28x22 mm), 330 TPI, 115 psi, 295 g

Continental Grand Prix 4-Season 28" — 22-622 (28x22 mm) is a road tyre designed for year-round riding, offering a balance of low rolling resistance, puncture protection and wet-weather handling. Built with a 330 TPI carcass and DuraSkin sidewall protection, this 28" tyre is intended for training, long-distance and everyday road use and is rated to 115 psi with a typical mass around 295 g. The tread profile and compound are tuned to provide predictable grip in varied conditions while maintaining efficiency on paved surfaces.

Advantages

The tyre combines a high-density 330 TPI casing with a Vectran puncture protection layer that reduces the risk of cuts and punctures without significantly increasing rolling resistance. DuraSkin sidewall fabric improves resistance to abrasion and sidewall damage in mixed conditions, extending service life while keeping weight moderate. The tyre’s construction supports high inflation pressures up to 115 psi for responsive handling and optimized rolling performance on smooth roads. Wet-weather traction and tread compound are designed to retain control in changing conditions.

Suitable for

• All-season road training and commuting
• Long-distance and endurance rides
• High-mileage cyclists seeking durable tyres
• Riding in variable weather, including wet conditions

Key specifications

• Wheel size / ETRTO: 28" / 22-622 (28x22 mm)
• Casing density: 330 TPI
• Maximum inflation pressure: 115 psi
• Approximate weight: 295 g
• Puncture protection: Vectran breaker layer
• Sidewall protection: DuraSkin polyamide fabric

How to use

Install the tyre onto a compatible 28" rim following standard tyre fitting procedures and use appropriate tyre levers to avoid damaging the bead or sidewall. Inflate gradually, checking pressure with a reliable gauge and do not exceed the maximum of 115 psi; select a lower pressure within the recommended range for comfort and grip when carrying loads or riding rough surfaces. Regularly inspect the tread and sidewalls for embedded debris or cuts, and replace the tyre if the puncture protection layer or casing shows significant damage.

Usage recommendations

For balanced performance and longevity, run pressures suited to rider weight and road conditions rather than always using the maximum. Clean and dry tyres after wet rides and remove small embedded debris promptly to maintain puncture protection effectiveness.
