Tire Service Advice

Protecting Against Flat Tires:

I’ve taken advice from motocross riders on ways to improve your chances of avoiding flat tires.

  • Avoid using slime sealant, as it is water-based and can cause your rim to rust over time.
  • Avoid using tire liners, as they can shift and disrupt the weight balance of the tire.
  • Use a thicker 2mm or 3mm tire tube for better flat tire protection.
  • Using a higher quality tires made by Michelin or Shinko to helps prevent flat tires.

Have a Spare Tube Ready:

  • Before attempting to patch or replace the tube, it’s a good idea to have a spare tire tube on hand.

Rim Protection Advice:

  • I recommend using tire removal rim protectors. When done correctly, you won’t scratch the rim. However, I’ve linked rim paint below in case things get messy.

Steps for Tire Removal:

  • Follow the motions shown in the video linked below. I personally use four tire iron spoons and rim protectors to ensure the quickest, cleanest removal that minimizes damage to the rim paint.

  • If replacing the tire, deflate it completely, then use tire levers to remove it from the rim.
  • Check the inner tube for punctures or damage, and replace if necessary.

Installing the Tire:

  • Mount the new or repaired tire onto the rim, ensuring the inner tube is properly seated without pinches.
