Why are there 'extra load' tyres on my Passat?

Hi Danny,

Extra load tyres are not usually needed on regular cars - they're usually found on people carriers etc. However, some tyre sizes are only available in 'XL' format so they're found on cars where that part of the tyre's specification is not strictly required. They tend to have stiffer sidewalls and are hence often used on low profile tyres. A car manufacturer may also specify this as part of how they want the car to drive on the road.

If that doesn't clear up your query please do come back to us.
