Weight distribution:   53 % Front tires / 47 % Rear tires
R r - the distance between the center of mass and the rear tires,
R f - the distance between the center of mass and the front tires
0.47 m · Rr = 0.54 m · Rf  /: m
0.47 Rr = 0.54 Rf
Rr + Rf = 2.46 m
Rr = 2.46 - Rf
0.47 ( 2.46 - Rf ) = 0.54 Rf
1.1562 - 0.47 Rf = 0.53 Rf
0.47 Rf + 0.53 Rf = 1.1562
R f = 1.1562 m
