Tire wear can be somewhat reduced by rearranging a pair of wheels on one side (same direction of rotation). In this case, their wear will be more uniform. Disadvantage of the method: when worn, all four tires have to be replaced. In addition, due to the repositioning at certain mileage intervals, it is more difficult to recognize possible violations in the suspension, steering or shock absorbers. When replacing, always make sure that in any case tires of the same brand, with the same profile and service life are installed on the same axle.
If you are not doing a wheel swap as described above, there is another option. Drive axle tires (in this case rear) wear out faster. If the rear tires are worn, they are replaced by tires from the front wheels, the wear of which is probably not less than the limit established by the standards - 1.6 mm. Thus, you only need two new tires. When the rear tires wear out again, they are also replaced with new ones.
