Tire professional inspection can query the local Michelin tire shop.2. tyres that have been calculated for more than 10 years from the date of production, we do not recommend continued use.

However, because many owners of the aerated tyre is hot, so check the pressure will be higher than the actual value, if inflation at this time according to the standard pressure, may be in low pressure state of the tire after cooling, so a lot of shop owners will be filling filling value slightly higher than the standard. Not too much depends on experience, so the numerical lacks accuracy. Therefore, when the tire is filled, try to keep the tire in cold condition, and the standard pressure should be detected under the condition of tire cooling.

These are tubeless tires.If it's a vacuum, it's 9R22.5-14 or 12R22.5-16
