I know this topic gets brought up all the time but I it appears to me that I have the dreaded RH5 wheels on my truck. Is that correct?

Front Wheel
Rear 1
Rear 2

Also are the front wheels (9-22.5 rubber) and the rear wheels (8.25-20 rubber) the same?

Finally, I have read through the Big Bolt Tech Tire Tips and it mentions that Accuride has a 5 and 10 hole wheel that might work for the AD trucks but what about new wheels for 6 hole pattern like this truck has?

Sorry for all the noob questions but I just recently got this truck to my house and am pretty excited to get working on this and budgeting for all the different parts and pieces.
