Pirelli Cinturato Gravel M Tyres: A Comprehensive Review
Pirelli's latest iteration of the Cinturato Gravel M tyres has undergone significant enhancements, positioning them as a versatile option for gravel cycling enthusiasts. These tyres boast a refined construction with a new SmartEvo GR compound and a more flexible ProWALL Gravel casing, aiming to deliver a harmonious blend of speed, grip, and comfort across varied conditions. While installation can be demanding and their weight on the higher side, the tyres' robust design and impressive performance on challenging terrains, including their proven resilience during the Gralloch UCI gravel race, underscore their value for riders prioritizing reliability and all-around capability over pure race-day lightness.
Pirelli has been diligently updating its tyre lines, extending these advancements to the Cinturato Gravel series. The Cinturato Gravel M HP, manufactured in Italy, shares its High Performance lineage with road models used by top teams such as Lidl Trek. This particular model occupies a middle ground within the Cinturato Gravel range, balancing the characteristics of the hardpack-oriented 'H' and the soft-condition 'S' variants. Notably, the 'RH' and 'RM' models are specifically designed for racing, featuring lighter construction and reduced rolling resistance.
The Cinturato Gravel M is engineered with a semi-slick central tread pattern, incorporating small grooves that optimize rolling efficiency on firm surfaces like hardpack gravel and tarmac. Conversely, its shoulders are adorned with taller, more widely spaced protrusions. This design element is crucial for maintaining superior traction on loose gravel and in muddy conditions, providing riders with enhanced control and confidence when venturing off smooth paths.
The tyre's current iteration features the advanced SmartEvo GR compound, a direct evolution from Pirelli's acclaimed SmartEvo road racing tyre technology. This compound is engineered for lighter rolling and improved grip, performing consistently well in both dry and wet conditions, on and off-road. Complementing this, the new ProWALL Gravel casing, with a density of 120 TPI (up from the previous 60 TPI TechWALL casing), promises a more pliable ride quality and enhanced deformation for quicker rolling. It also integrates reinforced sidewalls to shield against impacts and a protective belt beneath the tread to bolster puncture resistance.
During testing, a combination of 50mm front and 45mm rear tyres was utilized. The 50mm tyre, mounted on rims with a 28mm internal width, measured approximately 53.92mm, while the 45mm rear, on 26mm internal width rims, came in at about 42.7mm when inflated to 22psi. This tendency for Pirelli tyres to run wider than advertised is a significant consideration for frame clearance. The weight of these tyres also stands out, with the 45mm model weighing around 625g, making them heavier than some competitors like the Continental Dubnital 50mm, which weighs about 580g. This additional mass is a trade-off for their remarkable durability.
Despite the initial effort required for installation, the ride experience offered by these tyres quickly impressed. Although they might not feel exceptionally fast on tarmac, partly due to the lower recommended pressure, average speeds on paved roads were only marginally slower than with dedicated 30mm road tyres. However, their true potential comes alive on trails. The densely packed central tread facilitates excellent rolling on fire roads and compacted gravel, while the robust side knobs provide exceptional grip on loose terrain. The tyres' performance during the Gralloch UCI gravel race, known for its challenging conditions and sharp stones, highlighted their puncture resistance and dependable traction, instilling confidence even at high speeds and aggressive cornering. The differences in tread spacing between the 45mm and 50mm options proved beneficial for front-wheel traction, although extreme leaning on tarmac hairpins could feel less secure due to the larger gaps. Post-race inspection revealed minor cuts on the rear tyre, yet none had compromised the puncture belt, confirming their impressive resilience without any sealant loss.
While the Pirelli Cinturato Gravel M tyres excel in durability and all-condition performance, their weight could be a limiting factor for riders focused on competitive climbing or rapid accelerations. This often represents a compromise between minimizing weight for speed and maximizing resilience. Priced at £74.99 / $94.99, they fall into the higher end of the gravel tyre market, similar to race-focused models. However, their robust puncture protection, especially valuable in gravel racing where sharp objects are common, can prevent significant time loss from flats, thereby offering considerable practical value. The blend of smooth rolling, comfort, superior traction, and overall ruggedness makes them an outstanding choice for demanding off-road adventures, sharp gravel sections, and adverse weather conditions. Although not the cheapest option, their comprehensive performance ensures a rewarding riding experience.
Ultimately, the Pirelli Cinturato Gravel M tyres may not be the lightest or most specialized for racing, but they strike an impressive balance. Their upgraded design provides excellent rolling capabilities on various surfaces, a comfortable ride, and exceptional grip on challenging terrains. These tyres proved capable enough to qualify a rider for the Gravel World Championships, demonstrating that while other tyres might offer a slight edge in pure speed, the Cinturato M's resilience can prevent punctures and ensure consistent performance. They are not a budget option nor solely for hardpack, but their versatility makes them a top-tier choice for riders seeking a reliable and high-performing tyre across virtually all gravel conditions.
