Solid tires or air tires?

A repair shop's answer to the flat-tire question — how solid and pneumatic e-scooter tires differ, what a conversion involves, and which I fit for DC streets.

Written by Blake, who fits both. · Last reviewed

The short version

Side by side

Solid tires

You stop thinking about flats.

Punctures
None. There is no air to lose.
Ride
Firmer. You feel more of the brick and the pothole lip.
Grip in the wet
Slightly less forgiving on painted lines and metal.
Up-front cost
Higher — the conversion is labor plus the tire.
Running cost
Near zero until the tread is gone.
When I fit it

What I fit for commuters riding city streets daily, and for anyone who has already paid for two patches this year.

Air (pneumatic) tires

You keep the comfortable ride.

Punctures
The reason most scooters end up on my bench.
Ride
Softer. On a scooter with no suspension this matters a lot.
Grip in the wet
Better — the contact patch deforms with the road.
Up-front cost
Lower, and the tire itself is cheaper to replace.
Running cost
Sealant, valve stems, and the odd patch.
When I fit it

What I keep on machines with no suspension, on lighter riders, and on anything ridden for fun rather than for work.

If your scooter has suspension, solid tires cost you very little comfort. If it doesn't, think hard before converting — I'll tell you which camp yours is in when I quote it.

Why this question keeps coming up

Flats are the single most common reason a scooter arrives at my door. Not motors, not batteries — air. DC streets chew through pneumatic tires: construction plates, glass at the curb line, and the seam where the asphalt meets the streetcar rail on H Street.

So somewhere in most repairs, the same conversation happens: should I just go solid? The honest answer is that it depends on your scooter and on the way you ride, and that both answers are defensible. Here is how I think about it.

What a flat actually costs you

A patch is cheap. Two patches and a valve stem, plus the day you couldn't ride, start to add up — and a tubeless tire that keeps losing seal will keep losing seal.

If you are patching more than twice a year, the arithmetic has already made the decision for you. That is the point where I bring up conversion without being asked.

What you give up going solid

Comfort, mostly, and a little wet-weather grip. A pneumatic tire is a suspension component whether or not your scooter has actual suspension: it deforms over the pothole lip so your wrists don't have to.

This is the whole test, and it is worth stating plainly:

If your scooter has real suspension, solid tires cost you very little. If it doesn't, you will feel every joint in the sidewalk.

The other thing worth knowing is that solid tires are harder to fit. That is my problem, not yours, but it is why the conversion is priced as labor rather than as a tire swap.

What a conversion involves

The wheel comes off, the old tire and tube come out, the rim gets cleaned up, and the solid tire is pressed on — usually with heat and always with more force than seems reasonable. Then the brake gets re-centred, because the new tire almost never sits at exactly the same diameter as the old one.

On most scooters it is an hour or two of bench time. See the current rates for solid tire conversion and for a straight tire replacement, either kind.

How I decide, if you ask me to

  • Daily commuter, no suspension, mostly smooth asphalt. Solid. You will forget tires exist.
  • Daily commuter, suspension, mixed surfaces. Solid, and you will barely notice the change.
  • Weekend rider, no suspension, rough streets. Stay on air. The comfort is worth the occasional patch.
  • Heavy rider or a heavy machine. Usually solid — the puncture risk scales with the load.

Either way you get both options priced when I quote your repair, with the difference spelled out in dollars rather than in adjectives. Tell me what the scooter is doing and I will tell you which camp yours falls into — send a request and we'll sort it out by text.

Still not sure which one you want?

Tell me the scooter and how you ride it. I'll quote both, with the difference in dollars rather than adjectives.
