7.3 Tires
7.3.1 The condition of the tires is affected by the way you drive and use your
wheelchair.
7.3.2 Inspecting Tire Tread: please check the tread depth regularly. Replace
the tires when the tread depth is less than 0.5mm.
● When the tread depth is below 1 mm, the tire does not have good traction.
This may lead to vehicle slippage and makes braking distances much
longer. Thus, go to your Karma dealer to replace the tire as soon as
possible if it has less than a 1 mm tread depth.
● The tire pressure of all the front casters and the rear wheels must be kept at
50 PSI for the best drive range (maximum distance travelled per charge)
and usage/ handling.
