CORRECT TYRE READING
Below, please find the instructions
needed to understand the meaning of
the code stamped on the tyre.
The code may be in one of the ways
given in the example.
Example:
205/55 R 16 91 V
205 = Nominal width (distance in
mm between sides).
55 = Percentage height/width ra-
tio.
R = Radial tyre.
ZR = Radial tyre, with speed over
240 km/h.
16 = Rim diameter in inches.
91 = Load index (capacity), e.g.
91 = 615 kg. Not present in ZR
tyres.
W, Z = Maximum speed index. In ZR
tyres the speed index Z is be-
fore the R.
Load index (capacity)
60 = 250 kg 84 = 500 kg
61 = 257 kg 85 = 515 kg
62 = 265 kg 86 = 530 kg
63 = 272 kg 87 = 545 kg
64 = 280 kg 88 = 560 kg
65 = 290 kg
89 = 580 kg
66 = 300 kg 90 = 600 kg
67 = 307 kg 91 = 615 kg
68 = 315 kg 92 = 630 kg
69 = 325 kg 93 = 650 kg
70 = 335 kg 94 = 670 kg
71 = 345 kg 95 = 690 kg
72 = 355 kg 96 = 710 kg
73 = 365 kg 97 = 730 kg
74 = 375 kg 98 = 750 kg
75 = 387 kg 99 = 775 kg
76 = 400 kg 100 = 800 kg
77 = 412 kg 101 = 825 kg
78 = 425 kg 102 = 850 kg
79 = 437 kg 103 = 875 kg
80 = 450 kg 104 = 900 kg
81 = 462 kg 105 = 925 kg
82 = 475 kg 106 = 950 kg
83 = 487 kg
Maximum speed index
Q = up to 160 km/h.
R = up to 170 km/h
S = up to 180 km/h.
T = up to 190 km/h.
U = up to 200 km/h.
H = up to 210 km/h.
V = over 210 km/h.
ZR = over 240 km/h.
W = up to 270 km/h.
Y = up to 300 km/h.
Maximum speed index
for snow tyres
Q M + S = up to 160 km/h.
T M + S = up to 190 km/h.
H M + S = up to 210 km/h.
