Off road bicycle wheels made using incorrect rims?

[RandDenner]

Describe the bug

The 27" off-road bicycle wheels are using the wide steel rim that wide vehicle wheels are also using, and not the bicycle rim.

Steps To Reproduce

Just spawn them and look at the item info panel.

Expected behavior

That bicycles don't use huge car tire rims.

Ping: @occulti, this is your PR. Was this intended?

[RandDenner]

Oh, also the lengths are too small. All are 254mm, which is 10 inches.
17" is 432mm, 20" is 508mm, 24" is 610mm, 27" is 686mm

Also, volume is off.
Using the formula for a cylinder and a spreadsheet, I find that the volumes are pretty low, too.
Bicycle rim (27", 30mm wide) = 11L, motorcycle (20", 60mm wide) = 12L, medium steel (17", 190mm wide) = 28L, wide steel (24", 240mm wide) = 70L. (That 70L isn't a typo. Those are huge.)

Sounds like the motorcycle would be a better bet for matching, if off-road bike wheels are indeed wider in the rim (IIRC, they are).

@RandDenner Not intentional but an oversight - the intention was for off-road bicycle wheels to use the bicycle rim but I must have copy-pasted and not changed.

Thank you for the calculations too - the originals were just best guesses based on the dimensions and volume of the wheels themselves but these are much more accurate, will look to adjust now.

Not so much wider that bicycle rims don't still basically make sense.
narrower ones use around 20 mm, wider ones are about 30mm, which I used for calculations.
Both are a lot narrower than motorcycle rims, but also a greater diameter (27" as opposed to motorcycle 20").
