The Plyrating is still used in Europe, thoug for instance 8PR does not mean anymore that there are realy 8 ply's used in the tire.
Only means that it can hold yust as much pressure in as the old plyrating tire.
Yust another way of expressing instead of Loadkind.
Gathered this information and put it in a picture.
Not ready completely and blue printed means I am not shure if this name or pressure is used , and left empty I did not now.
Here the picture so you can see the differences between American and European system.
Notice the differce of 50/55 psi for C-load/6PR and the different PSI's in Europe used for D-load/8PR wich could give failures in the lists if an european tire is used in the American market.
Do tyres in Europe that are not stamped "DOT" actually say "6PR" or similar?
A tire stamped "DOT" is going to be confusing as it is trying to meet two different set of standards.
When walking the dogs I looked on a Truck tire.
Gave the same number combinations as is given behind DOT so xxxx/yyyy/zzzz/wwjj but no DOT before it.
Gave only single loadindex 160L and second 158M on sidewall.
Gave both loadrange J and 18pr .
So I think because no DOT to it they allowed themselfes to give double system.
Was a very wide tire so probably only used in single load , so no Dual load maxload given.
EDIT: yet another truck-tire seen, same Loadindexes but now DOT before the numbers and verry small LR L with 900kpa/130 psi.
Wonder why they skipped LR K
Because
H-load LR H = 120 psi
J-load LR J = 125 psi
L-load LR L = 130 psi
that I load is skipped is because it lookt to much J, but K??
