Tyre speed ratings
The chart below lists many of the 
different speed ratings currently being 
used for passenger vehicle tyres. The 
speed rating is part of the tyre size 
designation on the sidewall of the tyre. 
This symbol corresponds to that tyre’s 
designed maximum safe operating 
speed.
Speed Rating

S 112 mph
T 118 mph
H 130 mph
V 149 mph
W 168 mph
Y 186 mph
3.  Checking tyre life (TIN : Tyre 
Identification Number)
Any tyres that are over six years old, 
based on the manufacturing date, 
(including the spare tyre) should be 
replaced by new ones. You can find 
the manufacturing date on the tyre 
sidewall (possibly on the inside of 
the wheel), displaying the DOT Code. 
The DOT Code is a series of numbers 
on a tyre consisting of numbers and 
English letters. The manufacturing date 
is designated by the last four digits 
(characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a plant 
code number, tyre size and tread pattern 
and the last four numbers indicate week 
and year manufactured.
For example:
DOT XXXX XXXX 1520 represents that the 
tyre was produced in the 15th week of 
2020.
4. Genesis exclusive tyre
Genesis recommends that tyres designed 
specifically for Genesis vehicles be 
used. You may find the marking “GOE” 
(Genesis Original Equipment) embossed 
on the tyre sidewall.
5.  Tyre ply composition and material
The number of layers or plies of 
rubber-coated fabric in the tyre. Tyre 
manufacturers also must indicate the 
materials in the tyre, which include steel, 
nylon, polyester, and others. The letter 
“R” means radial ply construction; the 
letter “D“ means diagonal or bias ply 
construction; and the letter “B” means 
belted-bias ply construction.
6. Maximum permissible inflation 
pressure
This number is the greatest amount 
of air pressure that should be put in 
the tyre. Do not exceed the maximum 
permissible inflation pressure. Refer to 
the Tyre and Loading Information label 
for recommended inflation pressure.
7.  Maximum load rating
This number indicates the maximum 
load in kilograms and pounds that can 
be carried by the tyre. When replacing 
the tyres on the vehicle, always use a 
tyre that has the same load rating as the 
factory installed tyre.
