Description
The 380/90R50 is our most common selling rowcrop size for this tractor as well as our top selling size across our whole range of wheels.
BKT are a good mid-range tyre, however if the tractor will be carrying a mounted fert spinner or pulling a heavy trailer then we’d recommend a tyre with a higher load rating such as the Maxam (set code A0051-CA-1) or the Mitas (set code A0056-CA-1).
The BKT is rated to carry 6.9 ton across the back axle, the Maxam and Mitas are rated to carry 9 ton across the back axle.
This set is available in trackwidths from 72″ to 80″.
Also available with adjustable rims for £650 extra – set code A0052-CA-1-ADJ.
