i want to move to a 10 or 12" wide REAL WHEEL wheels. but i have now idea what back spacing i should get.

Dumb question but why do you want REAL wheels? Wouldn't it be cheaper to just buy some fancy chromes or something that will come with the correct bolt pattern? Only reasons I know of people going to those are backspacing, really wide wheels, and if they have Rockwell 6 bolt pattern.

Measure the backspacing you have now and go from there. From what I've read, wider rims still have the same back spacing. Check out http://www.mrt-wheels.com/. They have a bunch of information on their site, and their wheels are cheaper than Real, and they will do custom backspacing. If you have rear brakes, that might limit the amount of backspace you can do.

i just like the plain chrome wheel look. We got diesel pullers around here running 20 inch blings with rubber band tires. i just like the simple chrome wheel with no holes in it other then the ones used to mount the wheel. If i could find some cheaper that would be sweet. My dads wants to buy my current ones and tires. I want to move to a wider slightly more aggresive tire

they really not that pricy real wheels 16x12 with the bolt pattern i need 8x6.5 are $300. The ones i got now where $270. but i need more hp then fancy wheels right now so that idea will get put on the shelf for awhile.

You want full reverse rims on the front and as much postive offset as you can get on the back

Why

So your front wheels arnt fillin your back wheels tread pattern

Some of our guys are takin a full reverse rim and mounting them backwards on the rear axle to really get a full offset from the front

Another secret is to run 1/4" toein so the dirt is thrown well outside the rear wheel track
