Tyres used in Rallying are highly technical products with a life expectancy which seldom exceeds 80 km (50 miles). A dog's life during which they are subjected to violent impacts and tremendous forces considering their small size and the power of IRC cars. There are 200 materials in a rally tyre, and each one has to interact with the others. One can therefore understand what intense work the BFGoodrich chemists, developers and technicians must carry out to find the magic formula which will give the drivers exceptional grip and excellent endurance on asphalt, dirt or ice.

Asphalt tyres
On dry asphalt, the stresses exerted on the tyres are enormous: brutal braking (up to 1.8 G), high cornering speeds and strong lateral forces (up to 1.5 G). On asphalt, priority is given to outright tyre performance, but the drivers also want reliability. BFGoodrich tyres are both consistent and highly efficient.

Dirt tyres
There are various types of rally run on dirt (slightly wearing ground, moderately wearing ground and very abrasive ground). Depending on the rally, the tyres need to be precise, responsive and/or robust. BFGoodrich offers three types of compound (soft, medium, hard) to cope with all conditions. BFGoodrich tyres won all the dirt rallies in the 2007 championship.

Snow tyres
There is no IRC winter competition, but BFGoodrich is present at various Scandinavian championships, many of which are fought entirely on snow and ice. Each tyre has approximately 380 studs bonded into the blocks of rubber.

BFGoodrich Long-distance Rally tyre range

They too, are round and black with gray matter inside. But unlike IRC Rally tyres, Cross  Country Rally tyres are much more bulky; they are veritable giants made of rubber and steel ready to conquer all the hostile regions on earth. Unlike their IRC counterparts, All-terrain tyres have to travel several hundred miles per day under a torrid sun, in soft sand or on rocky paths, through camel grass or on dead-straight tracks at more than 180 km/h (112 mph).

Underneath the rugged grooved outer casing, Cross Country Rally tyres are enormously strong and versatile products, capable of withstanding extremely violent impacts due to the "truck-like" weight of the automobiles.
