Make sure they are built to handle the higher pressures and loads these tires will carry.” PRECISION INFLATION, “ It is important to remember that RCI is a great guide however, sometimes a tire will have a rolling circumference between groups or have variation between manufacturers- that is why we recommend contacting your local tire dealer to ensure lead lag is correct based on ACTUAL Rolling Circumference.”īKT, “Because of the increased air pressures and load carrying capacities of IF/VF tires, it would be wise to check the standard wheels being used. If you have a “negative” slip result, the front tires will experience a braking effect that creates a loss of pulling power, more fuel consumption and reduced steering capability.” MAXAM, “If you have too much positive slip ratio (above 5%) you will have “excessive” work by the front tires pulling the rear tires equates to a loss of efficiency and higher fuel consumption.
2 % Tolerance), which means a factor of ~1.054.”ĪLLIANCE, “If you are working with the Rolling Circumference Index group system, most MFWD tractors need to have fronts and rears that are 5 steps apart in the RCI, like a 50 Group in the rear and a 45 Group for the fronts.” The next higher RCI is always ~5.4% higher (+/. TITAN, “The tire industry has developed the RCI (Rolling Circumference Index) system based on the OD (Overall Diameter) of tires to assist manufacturers in the proper of selection of tire size combinations that will work.”ĬONTINENTAL, “The Rolling Circumference Index (RCI) is a grouping of tires based on the rolling circumferences. TRELLEBORG, “There is not a tire combination that is a “one size fits all” situation and often different operations would require different sets of tires for the same equipment.”
