ASK RIDE… How do you know if your tyre is glued on well?

How do you know your tyre is glued on well? What signs should I be looking for? Should I be using a bit of force to push back the tyre to test the gluing?

If you are wanting to know “if” a tyre has been glued properly we need to start with the installation of the tyre. If you follow these guidelines, along with your own methods learnt along the way, then you can be assured your tyres will be mounted securely.

There are numerous methods for attaching tubular tyres to rims and most depend on the usage of the wheels. I know a number of triathletes who use only a small amount of glue so they can change the tyre in a race if they get a puncture. There are also those who leave a small strip on the rim almost devoid of glue so they can use it as a starting point for removal. Let’s assume you want to use them for road racing in which case they need to be rock-solid to the rim.

1. Firstly mount the new tyre to rim and inflate it to around 60-70psi. Adjust the tyre so it sits straight and even on the rim. Leave it for a day or so to stretch out. This also gives you idea of how tight it will be to install at gluing time.

2. Remove the tyre and clean the rim so it is free of dust or big lumps of old glue. Apply 2-3 thin coats of glue to the rim and a coat to the tyre. Inflating the tyre to 50-60psi will turn the base tape upward making it easier to glue. Allow the glued rim to dry between applications. Leave the wheel and tyre overnight.

3. Apply a final coat of glue to the rim and tyre, wait for the rim to become tacky (not wet) and then mount the tyre to the rim by starting at the valve. You may need someone to help to make sure the tyre is pulled evenly over the rim.

4. Inflate to about 60psi and give the wheel a roll on the ground.

5. Put the wheel in a bike or truing stand and shift the tyre around until it is centred and there are no high or low spots. Leave the wheel for at least 12 hours if not more.

6. Pump to the required pressure. The tyre should be firmly attached to the rim and will not budge if you try to roll it off with your hands.
