Description
The 710/60R30 is the most common flotation wheel for the JCB 4000 series. There are two options, the IF BKT and the VF Bridgestone.
The BKT is the cheaper of the two options, however it is still an IF tyre so can run at 20% lower pressure than a standard tyre (such as the Trelleborg or Mitas). The Bridgestone is a VF tyre, so can run at 40% lower pressure – the ultimate option for low ground pressure and flotation.
Since 2020, the 4000 series JCB’s have come with 12 stud axles. If you have the older JCB 4000 series with 10 stud axles, we can still supply these wheels. The price will be the same – contact us for more information.
The maximum weights these tyres can carry is as follows:
Load Rating: 168D Will carry 5,600kg up to 65kmh
The BKT Agrimax Force is an IF tyre. Below are the weights you can carry with these BKT tyres at the lowest pressure possible.
At 9psi (0.6bar) this tyre will carry 2,575kg up to 65kmh
