Yokohama A036 gravel rally tyres. A tried and tested rough surface tyre from Yokohama, which was devised to deal with hard compacted surfaces, whether that be gravel, abrasive concrete, rough tarmac and on other types of hard surface. The directional tread pattern, in a soft compound, provides superb traction with efficient clearing and water, but must be used in pairs on each axle to ensure the correct balance. The reinforced sidewalls resist cuts and punctures. A very capable and reliable gravel tyre, in a couple of 15″ sizes.
