Scale question
 
Ok I'm basing my project off of tires on my towtruck the dolly tires they are 16 inches tall. The heavy duty wrecker I'm doing the project on has 40 inch tires. Do I divide 40 into 16 and get 2.5 and just take every measurement on the truck divide it by 2.5 and that's my measurement for my project build

Just divide everything by the ratio if the tires.

Ok can you explain that alittle bit better can you break it down for me

RE: Scale question
 
The tires are 2.5 times smaller, so everything else is 2.5 times smaller.

So I was right take all the measurements on the real truck put them in inches n divide by 2.5

It's a 24volt wheelchair motor it weighs about 16 pounds. What are you building and how big

Those wheelchair motors have serious torque.

If the rig is base on something with 40in wheels, I'd say torque is what it's all about. Huge wheels ROCK!
