What do XL and Reinforced mean on a tyre?

XL and Reinforced tyres explained

XL (Extra Load) and Reinforced are two terms for the same thing. Both indicate a tyre with a stronger internal construction, designed to support heavier loads at higher inflation pressures. Different manufacturers use different labelling, but the specification is essentially the same.

How they differ from standard tyres

Feature	Standard tyre	XL or Reinforced tyre
Sidewall construction	Standard	Reinforced with additional material
Maximum load capacity	Lower	Higher for the same size
Required inflation pressure	Standard	Higher, check your vehicle handbook
Ride comfort	Softer	Slightly firmer due to stiffer sidewalls

Important

If your vehicle was fitted with XL or Reinforced tyres from the factory, always replace them with the same type. Fitting standard tyres on a vehicle designed for XL could lead to tyre failure under normal loads. Our registration search handles this automatically and will only show the correct specification for your vehicle.
