Apollo City Flat Tire

Your Apollo City is a blast to ride. Until you hear that telltale hiss and feel the rear end get squishy. A flat tire can kill your whole day, and if you handle it wrong, it can wreck your wheel or send you over the handlebars.

Manufacturer specifications indicate the Apollo City uses a tubeless, split-rim wheel system. This design is simpler to repair than a traditional tube tire, but it demands a specific approach. Too many riders grab the wrong tools or skip critical steps, turning a 20-minute fix into a costly replacement.

Quick Answer

A flat tire on an Apollo City is almost always repairable. Use a rope plug kit made for tubeless tires. Remove the wheel, locate the puncture, and insert the plug.

Inflate to 45 PSI and check for leaks. Replace the tire if the sidewall is damaged or the tread is worn. Do not ride on a flat tire.

Apollo City Tire System Explained – Tubeless, Split-Rim, and Why It's Different

The Apollo City does not use an inner tube. It relies on a tubeless tire that seals directly against the rim. This is the same basic technology your car uses.

When you get a nail puncture, the tire can often hold air long enough for you to get home.

The wheel itself is a two-piece split-rim design. Six bolts hold the two rim halves together. This means you can separate the rim to remove the tire without heavy machinery.

In our research, this makes the Apollo City one of the more user-friendly scooters for DIY repairs.

Why Tubeless Matters for Repairs

A tubeless tire lets you patch the puncture without removing the entire tire from the rim. A rope plug goes in from the outside. The repair takes ten minutes and does not require a tire machine.

What Is Inside the Tire

There is sealant pre-installed from the factory. It coats the inside of the tire and seals small punctures automatically. Over time, this sealant dries out.

If you have had your scooter for six months or more, the sealant may no longer be effective. Replenishing it is part of routine maintenance.

Tire Specifications

The Apollo City uses a 10-inch tire with a street-friendly tread pattern. The recommended tire pressure is 45 to 50 PSI. Running below 40 PSI increases your risk of pinch flats.

Running above 55 PSI can cause a blowout on rough roads. Stick to the middle of the range.

How to Diagnose a Flat on the Apollo City

Not every loss of air is a puncture. Before you pull the wheel off, confirm you actually need to. Here is how to tell what is going on.

Check the Valve Stem First

A leaking valve stem is an easy fix. Spray soapy water on the valve. If you see bubbles, the core is loose or the seal is bad.

Tighten the valve core with a small tool. If that does not work, replace the valve core. It costs about one dollar.

Listen and Look for the Puncture

Pump the tire to 50 PSI and listen for the hiss. If you cannot hear it, run your hand slowly around the tread. Be careful not to cut yourself on glass or metal shards.

Mark the spot with chalk or a grease pencil.

The Soapy Water Test

Mix a few drops of dish soap with water in a spray bottle. Spray the entire tire surface. Look for a stream of tiny bubbles.

That is your puncture. If you find no bubbles and the tire is still losing air, the leak is likely at the rim bead. That requires removing the tire and cleaning the bead seat.

When It Is Not a Flat at All

Sometimes the tire feels low because the sealant has pooled inside and thrown the wheel out of balance. This feels like a wobble, not a gradual air loss. Check the pressure with a gauge before assuming you have a puncture.

If the pressure is normal and the ride feels off, the sealant needs redistributing, not repairing.

Step-by-Step Repair Guide – Rope Plug Method

Once you have confirmed a puncture, the rope plug method is the fastest and most reliable way to fix it. This works for punctures up to about a quarter inch in diameter. Larger holes or sidewall damage mean you need a new tire.

Tools You Will Need

Get these together before you start. Nothing is worse than having the wheel off and realizing you are missing a tool.

Step One: Remove the Wheel

Flip the scooter onto its side or use a stand. Disconnect the brake wire if your model has a mechanical disc brake. The Apollo City uses a drum brake, so you do not need to realign calipers.

Remove the axle nut and slide the wheel out.

Step Two: Locate and Prepare the Puncture

Pump the tire to 50 PSI and confirm the leak location. Use the reamer tool from the plug kit to clean and roughen the puncture hole. Push it in and out several times.

This rough surface helps the plug bond to the rubber.

Step Three: Insert the Plug

Thread a rope plug through the eye of the insertion tool. Both ends should be even. Coat the plug with rubber cement or the lubricant included in your kit.

Push the tool firmly into the puncture until about half the plug is inside. Pull the tool straight out. The plug stays in place.

Step Four: Trim and Seal

Cut the excess plug leaving about an eighth of an inch sticking out. Do not cut it flush. A small nub helps the plug stay seated.

Spray soapy water over the repair. If you see bubbles, press the plug deeper or add a second plug.

Step Five: Inflate and Reinstall

Inflate the tire to 45 PSI. Check the bead is seated evenly around the rim. You should hear a pop as the bead locks into place.

Reinstall the wheel and torque the axle nut to 30 foot-pounds. Test ride at low speed before resuming normal use.

Common Mistakes That Ruin a Flat Repair

Even experienced riders make errors here. These mistakes turn a quick fix into a wheel replacement.

Using the Wrong Type of Plug

Bicycle tube patches do not work on tubeless tires. They are not designed to handle the pressure or the rubber compound. Use a rope plug specifically rated for tubeless tires.

The kit costs under 15 dollars and includes everything you need.

Over-Tightening the Split-Rim Bolts

The six bolts on the rim only need 105 to 120 inch-pounds of torque. That is about 9 to 10 foot-pounds. Going tighter can strip the threads or warp the rim halves.

If you strip a bolt, the entire rim may need replacement. Use a torque wrench.

Riding Immediately After the Repair

The plug needs to cure. Wait at least one hour before riding. Better yet, let it sit overnight.

The rubber cement forms a chemical bond that needs time to set. Riding too soon can push the plug out.

Ignoring the Sealant Level

Even after a successful plug repair, the sealant inside the tire is still there. If it is old or dried out, the next puncture will not seal on its own. Top up the sealant every three to six months.

Two to four ounces per tire is sufficient.

When to Replace vs. Repair the Tire

Not every flat can be fixed. Knowing the difference saves you time and keeps you safe.

When Repair Works

You can repair a puncture in the tread area that is smaller than a quarter inch. The hole must be a clean circular puncture. Nails, screws, and small glass shards usually fall into this category.

One rope plug handles these repairs reliably.

When You Need a New Tire

Replace the tire if the puncture is in the sidewall. Sidewall damage cannot hold a plug safely. The flexing of the sidewall will work the plug loose, and you will have a blowout.

Replace the tire if the tread is worn below 1 mm of depth. The tire has no grip left, and the rubber is thin enough that punctures go straight through.

Replace the tire if you have more than three repairs in the same tire. Multiple plugs weaken the structure. At that point, a new tire is cheaper and safer.

How Much a New Tire Costs

An OEM replacement tire for the Apollo City costs between 25 and 40 dollars. That is a small price for peace of mind. You can find them through the manufacturer's website or authorized dealers.

As of 2026, several aftermarket options also fit the 10-inch split-rim wheel.

Prevention – Keep These Flats Away for Good

You cannot avoid every nail on the road. But you can dramatically reduce how often you deal with flats.

Maintain Proper Tire Pressure

The single most important prevention step is checking your tire pressure weekly. The Apollo City manual calls for 45 to 50 PSI. Under-inflated tires flex more and pinch against the rim.

This causes snake bite flats, which have two small holes right next to each other. A tire gauge costs five dollars. Use it.

Keep Sealant Fresh

Factory sealant lasts about six months. After that, it dries into a rubbery mess that no longer seals punctures. Open the tire, pour in 2 to 4 ounces of fresh sealant, and reinstall.

Brands like Slime and Armor-Dilloz work well. This one step cuts your flat rate by at least half.

Ride Smart

Glass and debris collect in certain places. Avoid riding through intersections right after a rain. Water washes debris to the lowest point.

Avoid the shoulder of the road where nails and screws accumulate. Scan the road ahead. If you see a shiny patch, ride around it.

Inspect Your Tires

Look at your tires before every ride. Check for embedded glass, nails, or cuts. If you find something, remove it with pliers.

If the object is small and the tire holds air, you caught it before it became a flat. If the object is large, leave it in and repair the tire properly.

Frequently Asked Questions

Can I use a bicycle tube patch on my Apollo City tire?

No. Bicycle tube patches are not designed for tubeless tires. They cannot handle the pressure or the rubber compound used in scooter tires.

Use a rope plug kit made for tubeless tires. It costs under 15 dollars and creates a permanent seal.

How often should I replace the sealant in my Apollo City tires?

Replace the sealant every three to six months. Factory sealant dries out over time. If your scooter is six months old and you have not refreshed the sealant, the tire will not self-seal small punctures.

Pour 2 to 4 ounces of fresh sealant per tire.

What PSI should I run in my Apollo City tires?

The manufacturer recommends 45 to 50 PSI. Running below 40 PSI increases your risk of pinch flats and snake bites. Running above 55 PSI risks a blowout on rough roads.

Check your tire pressure weekly with a gauge. Cold tires give the most accurate reading.

Can I ride on a flat Apollo City tire to get home?

No. Riding on a flat tire damages the sidewall permanently. A damaged sidewall cannot be repaired.

You will need a full tire replacement instead of a simple plug. If you get a flat, stop riding immediately and either repair it on the spot or call for a ride.

How long does a rope plug repair last?

A properly installed rope plug can last 500 to 1000 miles. It is considered a permanent repair for small punctures. Check the plug after the first week.

If it holds air, it will likely hold for the life of the tire. Replace the tire if you notice the plug leaking or the tread wearing thin.

What size tire does the Apollo City use?

The Apollo City uses a 10-inch tubeless tire. The exact size is typically marked as 10×2.5 inches. Aftermarket tires in this size with a similar street tread pattern also fit the split-rim wheel.

Always check the load rating on any replacement tire to match the scooter's weight capacity.
