Re: rim backspacing and to narrow or not to narrow

I know this "debate" is already over but.....I like it both ways, :D. These are what I put on my 68, 20 x 12's with 7" BS and 18 x 8's with 5" BS. I did this because I didn't want to narrow the rearend. If time and money were no object, I would have narrowed the rear at least 2" on each side. That being said, I really like the look that I have....

^^^ and we can see THAT WORKS with a disc brake set up

Tires are BFG gforce kdw's, 245/40/18 front, 25.7" tall, 335/30/18 rear, 25.9" tall. I would have liked to run the 275/35's in front, but of course, they came out after I got the 245's...

Too bad no one makes a 335/35 anymore because a 275/40 front and 335/35 rear would be BEAST :sumo:.

I realize this thread is old but I am wondering where you found 18x12 boss wheels?

I would suggest a Percy's Wheelrite and measure about 1000 times if you're going to spend that kind of coin on your wheels.

I agree with everything that has been said. .. Yes, a lot of combinations will work but what do you want it to look like on your truck (?) That (to me) is where you want to go with it. I think the narrowed rear end housing and 10" lip (obvious exaggeration) is a little too much but I still like a wider wheel tucked under the fender.

With a stock 69 housing you should be able to do a 10" wheel in the rear with 5" backspacing. (not tubbed) I like the look of a mild Mini-tub, in fact I'm considering it too. So, 22x13 with 8" BS and 3" mini tub without narrowing the rear end would work (in my mind) Narrow the rear end 3" on either side, and do the same wheel with 5" BS and it would sit about the same. 3" mini tub + 3" narrowed. That would be a huge lip. :D .. (prob a bit too much) Just examples and thinking out loud really. It really depends on how deep you want that lip'ped look. IMO, I'd look at narrowing the rear end if you have the $$. OR swap in a 9" or something (?) like others have said.

Re: rim backspacing and to narrow or not to narrow

I dont know guys.... in my other auto-circles.. deep dish wheels are on the way out. I had some on another vehicle and grew tired of the daily wipe downs needed to keep the brake grime, condensation, and dirty water spots off.

Edit -- im running 20x9.5 rims all the way around with a 5 inch back spacing. tires are 275/40/20. I got non-directional rubber too so I can rotate them without worrying about it.
