1.2. The pressure in the tyre is then adjusted as follows: U.K.

1.2.1. in standard bias — belted tyres to 1,7 bar; U.K.

1.2.2. in diagonal (bias-ply) tyres to the pressure shown below (bar): U.K.

Ply-rating	Speed category
	L, M, N	P, Q, R, S	T, U, H, V
4	1,7	2,0	—
6	2,1	2,4	2,6

3. The pressure is readjusted to that specified in section 1.2. U.K.

4. The overall width is measured by caliper at six equally-spaced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width. U.K.

5. The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by π (3,1416). U.K.
