Tires at the ITV: everything you need to know to pass the inspection

One of the most exhaustively analyzed elements during the ITV inspection is the wheel, which depending on its condition can prevent us from passing it satisfactorily. We explain what the technicians take into account.

Throughout our extensive series of practical articles we have touched on numerous tire related topics. From the types of tires that we can find on the market to the appropriate pressure or the fine we risk for driving with worn tires.

But, this time, we are going to delve into the inspection of tires and rims at the ITV, as it is one of the most important security elements and the technicians will not pass even one.

Tire defects

The first point to consider is whether the tires and rims of our vehicle have some kind of defect at the time of passing the inspection at the ITV station to which we have gone.

We must bear in mind that, regarding the wheels, there are no slight defects that allow us to circulate, but any type of anomaly automatically leads to the unfavorable inspection rating.

The depth of the plug must always be greater than 1.6 mm.

Thus, if the defect found is qualified as serious, we can drive solely and exclusively to take the car to a workshop. If the defect is considered very serious, we will have to resort to a crane.

Defects that will prevent us from passing the inspection are improperly mounted tires (it often happens that the direction of the tire is not respected), different tires on each side of the same axle or excessive wear (remember that the depth of the tread grooves must be greater than 1.6 mm; check it out with this simple coin trick). In the same way, we can suffer many other defects, being able to interpret them in the following way:


The tread depth is less than 1.6 mm The tire is incorrectly mounted Some tire without approval mark Excessive uneven wear on the tread due to incorrect inflation, alignment or balance Condition defects such as blisters, breaks , delamination or deformations Dimensions or characteristics not approved for that vehicle Different types of tires on the same axle Unauthorized regrooving Incompatibility between tire and rim Inappropriate snow (MS) or professional-use off-road (POR) tires Rubbing tire in other parts of the vehicle.

Very serious

Danger of bursting as a result of defects in condition Cracks or symptoms of breakage of the casing, showing cables of the structure.

Non-homologated tires

One of the aspects that can cause us to have an unfavorable inspection in the ITV is the use of a tire or rim size not approved. When we buy a vehicle, the ITV card specifies the measures allowed for it and we cannot use others without an approval process that makes them legal.

In many cases, some drivers tune or modify their vehicles to give them a different appearance or behavior, but each variation of the original state of the car must comply with regulations.

To find out more about the margins allowed in each area and how to approve a major modification, see our article on equivalent tires.

Checking the tires at the ITV

To be sure that we go to the inspection with guarantees, we must know what the wheel check process and the aspects in which the technician is going to look at the moment of it:

Tire dimensions and characteristics: Approval mark Speed ​​and load index That the tires of the same axle are of the same type Depth of the tread pattern If there is irregular wear No blisters, deformations, breaks. If cables or cracks are visible Correct mounting of unidirectional tires That the FRT (Free Rolling Tire-trailer) tires are not mounted on front or drive steer axles That the tire does not interfere with other parts of the vehicle If the tire tread has been redone, that they are marked with the word REGROOVABLE or the Ω symbol. If the car is equipped with a tire pressure monitoring system, check the correct operation of the warning light.
