Tyre manufacturer Michelin has introduced five new dimensions within its popular RoadBib agricultural tyre range, more than doubling the number of sizes now offered.

The new dimensions – 540/65 R30, 650/60 R34, 650/65 R34, 650/65 R42 and 710/75 R42 – take the number of sizes in the range up to nine and are available on both the replacement and original equipment markets.

Launched in 2018, the RoadBib is said by the manufacturer to be the first tyre for 200+hp agricultural tractors specifically designed to provide high performance, longevity and traction on machines used intensively on roads.

Henzell Enterprises in Northumberland took part in the pre-launch Michelin RoadBib tyre testing with a Fendt 828 Vario.

Commenting, Gordon Brookes, Michelin’s customer engineering support manager, said:

The Michelin RoadBib has been a huge success since it was introduced. The majority of farm and construction contractors typically spend more than 50% of their time on the road – which is the equivalent to 80% of their total distance travelled.

"These tractors are often coupled with heavy trailers, which only adds to the stress placed on the tyres.

"Our research and development team worked hard to find a solution that would solve these problems and design a tyre that would excel on tarmac and hard soil roads, whilst also performing well on soft soil in the field," he concluded.
