Tyres of size 14.00 R 20 are standard on the Zetros. The single tyres afford further traction benefits and additional ground clearance. Alternatives are of course available (optionally 395/85 R 20). Twin tyres are optionally available in different weight variants and sizes.
The spare tyre, wholly equivalent to the mounted tyres, is located securely under the frame on the left side of the vehicle, saving space and affecting neither the vehicle's breakover angle nor its ground clearance. And by means of the spare wheel jack it can be removed and replaced easily.
