The biggest tractor in the world, the 1,100hp Big Bud 16V-747 has taken advantage of Goodyear Farm Tires’ low sidewall (LSW) technology, after it was given its first tyre change since 1977. The Titan International agricultural tyre brand supplied Big Bud with 1400/30R46 tyres, fitting eight new rims and tyres. The giant tractor is housed at the Heartland Museum in Clarion, Iowa, its home for the last seven years.
