As a general rule, it is recommended to check your tyres at least once a month. This will help you catch any potential issues early on, such as low tread depth or uneven wear. Additionally, make sure to inspect the tyre pressure regularly, as underinflated or overinflated tyres can affect your motorhomes handling and fuel efficiency. If you frequently go on long trips or drive in challenging conditions, such as off-road or in extreme temperatures, it is advisable to check your tyres more frequently.
