Guys,
I have managed to get myself thoroughly confused with regards tyre load ratings etc...
So as far as I can tell the minimum load rating of the tyre is the maximum axle load divided by 2, then looked up on a load table to equate? Therefore the weights of the Z4M are -
Z4 M Roadster
Curb weight lbs/kg 3,203/1,453
Approved gross vehicle weight lbs/kg 3,821/1,733
Load lbs/kg 617/280
Approved front axle load lbs/kg 1,852/840
Approved rear axle load lbs/kg 2,006/910
Cargo bay capacity cu ft/liters 7.1/200
With convertible top compartment
panel folded up
cu ft/liters 7.8/220
Never exceed either the approved axle loads or the approved gross vehicle weight.
Z4 M Coupe
Curb weight lbs/kg 3,230/1,465
Approved gross vehicle weight lbs/kg 3,814/1,730
Load lbs/kg 584/265
Approved front axle load lbs/kg 1,885/855
Approved rear axle load lbs/kg 2,061/935
Cargo bay capacity cu ft/liters 8.7-10.6/245-300
Never exceed either the approved axle loads or the approved gross vehicle weight.
So taking the coupe as an example the max front axle load is - 855kg and the max rear axle load is 935kg. Therefore the minimum tyre load rating according the the table on Blackcircles is 79 front and 82 rear???
