NOTE: Radial ply tyres have a flexible
sidewall, which produces a sidewall bulge
making the tyre appear under-inflated.
This is a normal condition for radial ply tyres. Do
not attempt to reduce this bulge by over-inflating
the tyre.
1. Correct inflation.
2. Under-inflation.
3. Over-inflation.
4. Tread contact with road.
