If you're experiencing a flat tyre on your N70, don't worry. We're here to help you get back on the road in no time. Here are some steps you can take to diagnose and fix the issue:

1. Check the tyre pressure: The first thing you should do is check the tyre pressure. Make sure it's at the recommended level of 30PSI. If it's too low, inflate it to the recommended level. If it's too high, release some air until it's at the recommended level.

2. Check for air leakage: If the tyre pressure is at the recommended level and you're still experiencing a flat tyre, the next step is to check for air leakage. To do this, disassemble the wheel and soak it in water. Then, press it to check for bubbles. If you see bubbles, it means there's air leakage and the tyre needs to be replaced.

3. Replace the tyre: If you've determined that the tyre needs to be replaced, don't worry. We offer replacement tyres that are compatible with your N70. Simply contact our customer support team and we'll help you find the right tyre for your needs.

4. Prevent future flat tyres: To prevent future flat tyres, make sure to check your tyre pressure regularly and keep it at the recommended level. Also, avoid driving over sharp objects and rough terrain that can damage your tyres.
