First inspect the tyre and mark the area from outside where the nail or object has penetrated. Remember that the tyre can be repaired only on the tread area and not on the side wall. The illustration shown below shows the repairable area on the tyre.

Remove the tyre from the rim with out removing the nail or object, which has penetrated the tyre.

Inspect the tyre from inside and check for any internal damages which might have been caused due to the insertion of the nail or object.

Mark the tyre from inside also to identify it later. After inspecting the tyre, if the nail or object has penetrated the repairable area, pull out the nail and put the probe into the hole from where the nail has been removed to check the angle of insertion.

After checking the angle of insertion, check which size of the patch has to used, the 3mm or 6mm. Once that has been identified drill the tyre with the correct drill bit.

Keeping in mind the angle of insertion of the nail, drill the tyre from outside first and then from inside till the steel belts have been shaved off so that they don’t cut the stem of the mushroom patch.

Buff the inner liner of the tyre as per the patch size (3mm or 6mm) so that the patch can stick on the tyre properly or in general words just rough the liner so that the patch can have a grip on the tyre when stuck with the solution.

Spread the solution or cement on the area where the patch has to be stuck, and let it dry for a minute. Insert the mushroom patch from inside and pull it out from the plier so that it sticks to the tyre liner.

Stich the patch on to the tyre so that there is no air bubble on the sticking area, which could result in a leakage.

Stich the patch from the center to the side and then from center to top and bottom.

Leave it to dry for 1-2 minutes.
Fit the tyre on the rim and inflate it to the recommended air pressure. Cut the extra stem of the patch to the tread level on the tyre.

Spray the soap solution to check for leakage. Make sure to balance the rim after the repair.

The tyre is now ready for use. A speed rated tyre can be repaired 6 times.
