Why Your Basketball Has A Bump (And What You Can Do)

By Alex Mercer

December 14, 2019

Basketballs start to lose value and deteriorate when they leave the box and start hitting the ground. If it’s a concrete surface or a gym floor, a basketball’s impact over time will start to cause defects.

Some of the defects a basketball faces are the cracks (spider webs), and bumps found all over the ball. One of the main defects is a bump within the ball’s bladder.

Basketball tends to get bumps due to being overinflated or pumped up too fast. The ball’s bladder will not equally distribute the air and will take the path of least resistance, forming a bump.

In this article, we will show you why your basketball may have a bump and what you can do to fix it.

Why Does My Basketball Have A Bump?

Basketball bumps or lumps will form when the ball is overinflated or too fast. The air doesn’t have time to spread throughout the basketball and will be forced to one centralized location within the basketball.

This centralized location is often a weak spot in the ball bladder where the air is trying to escape. This is usually the case with over-inflated balls. Whatever contains the air, the bladder will expand, and any weak spot will develop a bump or lump.

Poor storage is another reason the bladder or synthetic material that keeps the air inside the basketball can ultimately weaken.

Balls stored in trunks or cold places will condense the air, which will cause the ball to deflate. Once it hits high temperatures, the ball will return to its natural state and re-inflate. Constant inflating and deflating of the basketball can cause the bladder to weaken.

Another reason, and the most common reason for a ball developing a bump, is overuse. Years-old basketballs will eventually start to wear down, both inside and outside. As mentioned, consistent pounding from dribbling will weaken the ball over time.

How Do I Remove A Bump From My Basketball?

There is no at-home solution to remove a bump from a basketball. Basketballs that often find themselves with a lump or a bump are usually, and in most cases, worthless.

The bump will continue to grow as the bladder inside of the ball weakens with the air pressure being forced against the bump as the ball dribbles.

However, there are a few ways to professionally get the bump removed if you’ve grown attached to your basketball.

Find A Leather Shop

This may seem extreme, but simply going to a leather shop and asking them to repair your ball may be in the cards. They will have to remove the top layer and completely repair the basketball’s inside part.

The process will be to either melt or reshape the bladder inside. It’s, of course, a tedious process, but if you’re hung up on your basketball and you want a quick fix, this may be your best option.

Purchase A New Basketball

No one likes getting a new basketball, especially if you’re comfortable and settled in with the handle of your current ball.

Purchasing a new basketball is not only a pain to do; spending money on one can also be a pain.

Basketballs can be pretty expensive, especially if you’re looking for a basketball that is mainly for pickup games.

Spalding Zi/O Basketball

The Spalding Zi/O basketball is a great indoor and outdoor multipurpose basketball. It can be used on any court and is tough enough for long-term use.

We recommend you take care of this basketball and store it properly. Poor storage, along with using it inside and outside, consistently can shorten the lifespan. The Spalding Zi/O basketball is the official NBA size and weight and comes inflated and ready to play as soon as the package is opened.


Basketballs, over time, will develop lumps through consistent use. This consistent use will often soften the basketball’s bladder.

To counteract the bump over time, ensure your ball is consistently regulated with proper air pressure. Once a lump or a bump in a basketball has formed, it’s nearly impossible to get out.

Storing your basketball properly will allow the ball to distribute the air temperature evenly. If the ball is stored in a cool space, then in a hot space, naturally, the air particles will expand and contract. This will put stress on the basketball’s bladder.

We strive to keep longevity with our basketballs, as buying a new basketball every couple of months can get expensive.

Take care of your basketball and store it properly, so the ball maintains its durability and uniform shape.
