What does code MB1 mean regards tyres

[jowen7448]

Am just looking at ordering some new tyres for the Zed comparing prices on oponeo, tyre leader and camskill. I notice a code next to tyre description I am not familiar with which is MB1 which I can't seem to find a description for. Does anyone know what this means. The reason I ask is they come out at slightly cheaper per corner than the same tyre without this code on the listing. Very confused.

It means they can be fitted to a vehicle not exceeding 2.7 tonnes.

Ah thank you very much. I know the zed is heavy but it ain't that bad so will get them ordered.
