Michelin Road 5 claims wet grip win

Michelin Road 5 maintains wet grip with age

Michelin’s new Road 5 tyre features a tread pattern that widens as it wears to maintain wet mechanical grip with age.

The French tyre manufacturer claims it won an in-house braking test against its five main rivals: Metzler Roadtec 01, Pirelli Angle GT, Continental Contiroad track 3, Bridgestone Battlax T30 Evo and the Dunlop Roadmsart II.Michelin Road 5 maintains wet grip with age

Remember, this is not an independent test, although they did have an unnamed “independent” witness on hand.

However, Michelin also compared the Road 5 tyre with its predecessor and found it stopped as quickly after 5000km of wear as a new Road 4.

Tread secret

The secret is in the tread that actually widens as it wears down.

It comes from their XST X sipe technology developed for road cars, but takes it a step further with XST Evo.

This technology features a combination of sipes (those narrow “cuts” on some tyres) and reservoirs. These are designed to slice through surface water and pump it away from the tyre’s contact patch.Michelin Road 5 maintains wet grip with age

New tyres have deep sipes which can pump out a lot of water. As they age, they lose that ability.

However, as the Road 5 tyre tread wears out, the XST Evo sipes reveal wider grooves to maintain its ability to clear water.

Dry grip

Michelin claims there are a couple of technologies that also improve the Road 5’s dry grip.

One is Michelin Power RS Adaptive Casing Technology that has a soft crown and stiff sidewalls for better high-speed stability and to handle sideways cornering forces.

Like many modern tyres the tyre come with two compounds in the one tyre with a harder compound in the centre for long life and a softer compound on the edges for more cornering grip.

The Road 5 also has the hard compound underneath the soft outer compound to provide more acceleration grip in corners.

Michelin Road 5 tyres cost about $300 for a rear and about $185 for a front and come in a wide variety of sizes: 120/70ZR17; 120/60ZR17 (front); and 150/70ZR17; 160/60ZR17; 180/55ZR17; 190/55ZR17; 190/50ZR17 (rear).Michelin Road 5 maintains wet grip with age
