Settling into your life as a new parent has its fair share of challenges. For one, your baby might be too young to be in a daycare, or you don’t want a sitter just yet. The thing is – you can bring your baby along for running everyday errands or simply getting back to your old routine. Most parents we know can swear by their bob stroller for the job.

What Are the Early Signs of Stroller Tire Failure?

Bob Gear has a great collection of single, dual, jogging, and travel strollers. Their easy-gliding wheels are hard to beat when it comes to quality and endurance. However, tires can get punctured, and you most likely won’t see it coming! A stroller with a defective tire can wobble, and you’ll feel a drag as you take turns. Before that even happens, here are a few warning signs you should look out for!

Bulges on the Sidewalls

So, you want to know when a flat is just around the corner. In that case, a regular tire inspection goes a long way. The second you spot a cut or a bulge on the sidewall, don’t wait up for the final blowout. It’s safer to change, repair or simply patch the tire than to put up with a bumpy stroller. Trust us when we say this – running a flat tire on grocery day is a royal mess!

Low Tire Pressure

An under-inflated tire sets off a chain of unfortunate events. First, it increases friction and makes it difficult for you to maneuver the stroller. In a way, it’s no different than the tires on your car. Stroller tires with a low pressure are subjected to uneven tread wear, overheating, and blowing out. So, our advice for you is to keep a bicycle hand pump and a tire lever ready. We’ve included an exclusive section on pumping stroller tires. So, don’t forget to keep an eye out for that!

Worn-out Tread

Depending on road and sidewalk conditions, stroller tires will wear out sooner or later. Old tires can’t grip the streets as securely as new tires. In fact, they can very much skid and move- making it a hassle for you to control the stroller. They also develop weak spots which, later on, get easily punctured from gravel, potholes, and debris. So, it’s best not to sit on worn-out tires and get replacements instead.


Stroller tires can vibrate when they get old. If you’re experiencing something similar, check the suspension as well. Bob strollers have shock-absorbing suspension forks under and around the seating area. Another reason could be a misaligned or bent wheel. The good news is Bob Gear offers an all-in-one flat prevention kit for their Revolution series strollers. You’ll also find tire liners, repair kits, and necessary tire-changing tools on their website.

Changing a Flat Stroller Tire: a Step by Step Guide

This is the part you’ve been waiting for, and we’ll get to it shortly. First, you’ll need a few tools for a successful tire change.

Tools You’ll Need for Changing Bob Stroller Tires

We’re listing down the necessary tools you’ll need for replacing your Bob Stroller tires. Make sure you have all of them in your toolbox!

Step 1: Remove the Wheels

There are two different procedures for the front and wheels rear. Find out more below!

Rear Wheel Removal

If one of the rear tires is flat, disengage the parking brake before you move forward. Press the quick-release lever and gently pull out the wheel. The latest Bob stroller models have a secondary retention switch for both of the rear wheels. It’s a small red button right next to the quick-release lever. Open the lever and press the red button-down. The rear wheel should come out easily. Now, if the front wheel needs changing, follow these steps instead.

Front Wheel Removal

Most Bob Strollers have a 360-degree swivel wheel at the front. Remember to lock the wheel in the forward position before you begin to remove it. Now, turn the quick-release lever of the front wheel and un-thread the adjustment nut. The wheel should come off in your hand at this point.

Step 2: Remove the Inner Tube

As for the second step, look for a small cap on the inner tube valve stem. Un-thread the cap and apply pressure to the bare pin with a flathead screwdriver. Keep at it until you deflate the inner tube completely (you should be able to hear a hissing sound). Slide the screwdriver tip in between the wheel and the tire. Put your palm on the axle to keep the wheel steady. Insert the second flathead screwdriver four inches apart from where you’ve lodged the first one.

By this time, you should see a small opening that reveals the inner tube. Repeat the process until the tire loosens up around the wheel rim. Gently pull the inner tube out and remove the valve stem. After this, disengage the tire from the rim. It takes a while, and it’s completely normal.

Step 3: Insert the New Inner Tube

Take a minute to check if the inner portion of the tire is damaged. If it’s good to go put the tire around the wheel rim, keeping the larger part of the diameter still disengaged. Take the pump and inflate the new inner tube till it forms its shape. Now, wiggle the inner tube in between the tire and the rim.

Line up the inner tube valve stem with the rim’s valve hole and push the pin through. Work your way around the tire until it reseats snugly on the rim. If any part of the tire feels difficult to align, use a flathead screwdriver like before.

Step 4: Inflate the Tire

Take the air pump once again and inflate the tire through the valve. Stop when you reach the specified tire pressure written on the rim. Put the cap back on the valve stem.

Step 5: Reinstall the Wheel

Lock the wheel hub on the stroller axle and be extra sure to engage its quick-release lever. As for the front wheel, start with tightening the tension-adjustment nut. The quick-release lever shouldn’t be moving while you tighten the nut. Keeping both of your hands on either side of the axle, push the lever to the closed position.

If you’ve correctly installed the front wheel, you should be able to see the word “Close” on the lever from the side. The lever should be parallel to the fort blade on the opposite side of the front wheel axle.

A point to note: Bob strollers with a fixed front wheel require the same installation process as the rear wheels. So, this is how you change Bob stroller tires. It took us only three tools and roughly twenty minutes for the job.

The Right Way to Pump Stroller Tires!

If you know how to correctly pump stroller tires, you can avoid mistakes such as over-inflating and under-inflating. We’ve also had cases where people damaged the valve stem- rendering the entire tire completely unusable. It’s time we showed you the proper way to inflate Bob stroller tires. Keep reading!

Take the Wheel off the Axle

It’s important that you start by taking off the wheel from the axle. For one, pumping a tire that is pressed against the ground might cause it to bounce up. The tire can end up misaligned, and the weight of the stroller is enough to finish it off. We won’t be taking chances if we were you!

Use a Hand Pump

You can use a foot pump, but we found it easier to inflate stroller tires with a hand pump. Now, unscrew the cap from the valve and thread the hand pump attachment on the stem. This is the part where you pump the tire until it’s inflated all the way. Remove the nozzle from the valve stem and put the cap back on.

Check the PSI Level

It’s good to check the tire pressure, especially for jogging strollers. An under-inflated tire will cause the chassis to lean on that particular side. It’s pretty inconvenient for both the baby and you. To check the PSI level, use a hand pump with a pressure gauge. The pressure gauge has an indicator that moves up as you pump the tire.

Safety Precautions

The max pressure level the stroller tire can bear should be written on the rim or sidewalls. Never inflate the tire all the way up. You want the tire to feel hard with a little bit of felx to give. Overinflated tires can tear off at the center and wear down unevenly. Pump the stroller 5 to 10 PSI short of the max level. It’s usually the ideal pressure for any stroller tire.

Bottom Line

With time and practice, it’ll be a breeze for you to service and change stroller tires. Anyway, we believe we’ve covered everything from pumping stroller tires to replacing them. In any case, you should find our early signs of tire trouble section quite helpful. So, if your bob stroller tires keep going flat, you know exactly what to do. Just bite the bullet and get that screwdriver out of the drawer! You got this!
