4X4 O/R XZL
Designed for multipurpose and obstacle-crossing 4X4 vehicles, the Michelin 4x4 O/R tyre is one of the preferred tyres of off-road specialists.
Traction. Impressive grip even in the most extreme conditions:
- On slippery surfaces thanks to deep tread design;
- On inclined surfaces with angular shoulders and massive tread blocks;
- Easy cleaning due to the massive, rigid and widely spaced tread blocks;
- Tyre pressure can be reduced to less than 1 bar in difficult obstacle-crossing zones thanks to the flexibility of the radial architecture.
Durability. Excellent resistance to perforations, aggressions and shocks, thanks to a metal crown ply, a triple protective band at the sidewalls and a double highly-resistant polyester casing ply.
It is obvious why this tyre has been selected by emergency services operating in extreme situations and several armies throughout the world.

Michelin 4X4 O/R XZL performances
Unfortunately we don't have a price for the tyre from this dealer at this time
Methodology for performance measurements
Sources refer to a market player who carries out independent tyre comparison tests, based on a stable methodology and broad performance criteria, to provide objective results for a range of similar tyres according to the type of use.
Only the sources that respect the criteria are included in the base. These criteria are also applied for every test source.
The sources used to establish the performances for a tyre are:
- Data from published tests from specialized media.
- Data from Regulation (EC) 1222/2009 "on the labelling of tyres with respect to fuel efficiency and other essential parameters". Or the most widely observed label values (MOBS) in the absence of official values*.
- Data published by independent test institutes.
Detailed list of the sources (not including Regulation (EC) 1222/2009) used to rate each product accompanies the display.
The structure of the ratings
The final rating is divided into 9 elementary performances, and an additional 4 elementary performances for winter tyres.
The elementary performances are grouped into 5 performance categories; 3 for summer tyres, and 2 for winter tyres.
Every elementary performance is integrated into its group with a different weighting according to its importance.
The performance groups and the elementary performances are as follows:
|General performances||Winter performances|
The methodology for the calculation
Every elementary performance is rated accordingly to the following princip:
- A score of 10 is given to a tyre which achieves the best result for a given test.
- The score given to other tyres decreases in proportion to the standard deviation of the selected discriminating factor.
- All results that are 9 times higher than this standard deviation obtain the score of 1.
If the source uses his own rating (when it is not on a base of 10), a linear transcoding is performed
The final score for the basic performance is the arithmetic average of the scores obtained for each test.
Note: Tests conducted by car magazines or specialised bodies generally cover the most common tyre dimensions available on the market. Even if performances vary slightly depending on dimensions, we have chosen to apply the rating to all dimensions for a tyre model.
