Yokohama ATG held a field day at well-known Youtuber Olly Harrison’s farm at Tarbock in Merseyside on March 27th to showcase the road going and self-cleaning capabilities of its Alliance AgriStar II, AGRIFLEX+ 372, AGRIFLEX+ 373 tyres and educate a whole host of farmers, contractors, tyre dealers and journalists on the benefits they offer.

The purpose of the tests that were carried out by Alliance’s European Field Engineer, Frederick Zandman, and European Field Manager, Gerritt Vinkers, on March 26th at Olly Harrison’s farm near Tarbock in Merseyside were to highlight the cost of comfort on the road. The results were then discussed and analysed with farmers, contractors, tyre dealers and journalists the following day.
Three of Olly’s tractors, a pair of Fendt 728 Varios and a Valtra Q265 fitted with Alliance AgriStar II, AGRIFLEX+ 372 and AGRIFLEX+ 373 tyres, each took turns with the same operator to pull a loaded Richard Western SRT20 dump trailer fitted with 560/60R22.5 tyres running at five bar of pressure on a route comprising 17.1km (10.6m) of single carriageway urban roads, a dual carriageway and narrow rural lanes.
