How to Fix a Flat Spot on a Bike Tyre

Overview

A flat spot on a tyre can affect handling. This guide covers fixing a flat spot on a bike tyre.

Step-by-Step Fix

1. Begin by checking your tyre's air pressure against the recommended PSI or BAR levels printed on the tyre sidewall itself. Using a reliable tyre pressure gauge, inflate or deflate the tyre carefully to match these specifications, as incorrect pressure can exacerbate flat spots or create new ones.
2. Carefully inspect the entire surface of the tyre, both the tread and sidewalls, for any visible signs of wear, cuts, punctures, or embedded debris. Pay close attention to the area where the flat spot is most prominent, looking for any deeper damage that might indicate structural integrity issues.
3. If the flat spot appears to be the result of a sudden skid, particularly if it's a pronounced, localised abrasion, it's highly likely that the tyre material in that area has been permanently compromised. This type of damage often means the tyre will not regain its original shape and will continue to affect ride quality and safety.
4. Should your inspection reveal significant damage such as deep cuts, delamination, exposed casing threads, or if the flat spot is severe and won't round out after correct inflation, it is crucial to replace the tyre entirely. Riding on a damaged tyre is unsafe and significantly increases the risk of a blowout, which could lead to a serious accident.
