I found these rubber caster wheels at Harbor Freight Tools for $3.99 on sale.
They required a bit of modificaiton to use with the skateboard.
I had to cut about 1/8" off the metal tube spacer to make them work,
and also use a large washer to hold everything in.
They have a plastic bearing cap, which wont work, so I used the washer instead.
They have their own bearings, which are prob not as good as ABEC bearings,
and also they are heavy (946grams vs. 270grams for Urethane stock wheels).
The ride is a lot smooother and more stable though.
Now, if I could only find 5" diam inflatable wheels with rims.
good find silentguy
any luck on finding a replacement wheel for the rear?
No, I havent found any rear replacement.
I am thinking I will just use Shoe Goo on it when it wears out,
or try to make a liquid urethand mold, and recast the wheel.
Another option would be to find a metal sprocket with teeth
that will fit the belt, and bolt it to an exisiting wheel.
I was thinking a double rear wheel set up with a bolted on or epoxied sprocket
would work.
I also found a good source for 125 mm scooter wheels,
$8.99 for a pair. These would work well for the front wheels.
125 mm - Green, Blue, Red, Orange - $8 Pair + $6 S&H
Here is the link.

that's a good price for the front wheels. I am now trying this 3M™ Polyurethane Protective Tape 8674
http://www.aircraftspruce.com/catalog/cspages/8674.php
I wrapped 2 layers of this tape on the rear wheel. Hopefully, it will last a long time.
Cool idea, the tape.
It seems kind of pricey though.
Let us know how it works out.
I know you can prob use something like Shoe Goo to add tread.
Also, liquid Urethane is prob not that expensive, but you need to make a mold of some sort.
The casters from Harbor Freight,
dont work all that well, becoz the bearings are not very good.
Unless you can modify them to use ABEC bearings I wouldnt recommend the casters.
These titan wheels are nearly identical to the G1's stock front wheels.

They dont come with any bearings, so thats probably why they are cheap,
however you can just use the old bearings as they fit.
I put the wheels from my Stowboard onto the G1,
and they are by far the best wheels I have used.
They are a bit smaller , 110mm, but are flat and rubbery.
Grip, and ride is very smooth.
Might also have something to do with the better bearings they use.
I will try and post some pics soon.
These wheels are hard to find too, as the Stowbard is discontinued.
Heres a link to site that used to sell Stowboard.
So you can see what the wheels look like
They are 82A durometer, so softer the standard 85A polyurethane wheels.
They are flat profile, and really smooth and grippy.

Heres a pic I found on net of stowboard wheels.
You can also find some 110mm 82A durometer Outdoor Inline Skate wheels
that should work well.
The good thing about the stowboard wheels is that they have a flat profile
and are very grippy.
A link to inline wheels that are 83A and 110mm.
$14.00 each, so not that expensive, in comparison to Goodyear wheels.

wow! those are very nice looking wheels, so they are an exact replacement? I haven't been using mine, have to upgrade batteries to LifePO4. How's your rear wheel holding up so far?
The Stowboard wheels are 110mm as compared to the stock 125mm wheels.
They work fine, better grip and smoother rolling.
My rear wheel seems fine, i think its going to last a long time.
I am more concerned about the drive belt, as I am down to my last one.
It's better to get a rolling start, before engaging power, as it's easier on the drive belt.
With 36 volts, theres a lot more torque on the drive belt.
Oh, the titan wheels are the same diam , 125 mm as the stock,
they dont come with bearings, and the plastic hub is a little bit different,
but they are for the most part almost the same as the stock wheels.
I think its better to try and find a bit softer wheels,
82A or 83A durometer seem to grip better on road surface.
