Questions about this item

What does the 124/120 load index mean for my trailer?

The dual load index shows maximum capacity: 124 for single-wheel fitment and 120 when the tyre is used in a dual-wheel arrangement on the same axle.

How does the M speed rating translate to real towing?

The M rating certifies sustained speeds up to 81 mph, so highway cruising at legal limits stays well within the tyre's tested envelope.

What does the E load range on a 16 inch rim cap in practice?

Load range E on a 16 inch rim delivers a 10 ply rating for heavy trailer loads while the 30.8 inch overall diameter maintains proper ground clearance and speedometer accuracy.
