I think it is only 30 bucks or so.
It only includes the INTERNAL profile of the rim, not the external dimesions. Designig a whole wheel requires a whole lot more than that.
Yes, it does include motorcycle rims.

Tire and Rim is the US based organization.
For the Japanese it is JATMA (Japanese Automobile Tire Manufacturers Association) and for the Europeans it is ETRTO (European Tyre and Rim Technical Organization).
Each of these organizations covers only what is designed in their region, so in particular, you'll want to get the JATMA book.
And as Greg said, the book only covers the area where the tire and rim interact (and the valve, too!) and not where the rim attaches to the vehicle.

I may have been misled by the Australian T&R book, which since our fleet is mostly imports, tends to cover a very wide range of sizes.
The other dimensions of a wheel rim have to be designed to suit the loads and life requirements.
For instance aluminium rims tends to have a problem with the wheelweight flange cracking or bending in square edge pothole tests. The exact solution to that is somewhat dependent on the tire size used, and the design of the wheel disk or spoke. Aftermarket wheels (by and large) tend to fail. There's a good SAE standard on the fatigue life of wheels.
Steel rims are a bit easier to think about, but designing the spider (wheel center) for a steel rim is much more difficult.

Greg,
What I think jus1975 was asking was about the dimensions near the hub - and I do not have a clue where to go for that - except for the vehicle manufacturers. And I doubt if they will share that!!

OK, sorry. Best source for wheel stud patterns is probably an aftermarket catalog!

I'm not just looking at the stud pattern but basically the whole rim. Everything needed to design my own. Its just a dream I have to have my own line of wheels. It would be a great addition to my shop. As far as designing and drawing the wheel would not be a problem. I have a problem with certain demensions before having cut. I understand their are companies that deal with the outer rims. Any info will be greatly appreciated.
jus1975,
Just so we're all clear and talking about the same thing here:
The rim is the area on which the tire seats. Calling the entire wheel a rim might confuse a person with a wheel background, so try to avoid it if you can.
As Greg & CapriRacer pointed out, you can get ALL rim area dimensions from the appropriate manuals that they mentioned.
The rest of the wheel design shape will not have any standards associated to it (in terms of dimensions) other than maybe the flanges for wheel weight fitment and it is up to you to engineer/design the remaining areas.
I would think that you'd be much better off just sketching/rendering some wheel designs and trying to sell them to aftermarket wheel makers....just my opinion though.

Some people are like slinkies....they don't really have a purpose, but they still bring a smile to your face when you push them down the stairs.

No need to apologize...I was only hoping to avoid any possible confusion due to terminology being used.
Good luck and post back if you have any additional questions.
