rear tire width question

[BB70c10]

does anybody know what the widest rim/tire you can run in the rear is without shortening the rear axle.im going to use aftermarket wheel well tubs in the bed, but dont want to shorten the axle.i plan on racing it some,but i want to run slicks at the track and still have chrome wheels on the street.backspacing would be helpfull also if available.thanks in advance

I run a weld rodlite 15x12 wheel with a 7.5 bs. tires are MT 29-15.5 sportsmans. In the bed i took a set of stock wheel wells and cut em and welded them together, also had to cut to my frame in the bed but it was pretty simple.

no i don t of that but its not that difficult what you do is take a stock wheel tub and measure the diffrence you need and take another and cut what you need out of the other tube to make how wide you need...then burn the two halfs together to make one good tub...as for the bed you measure how wide the tub is and then you just mark out where it falls and cut it out.. just make sure you leave enough of a flange to mount it to on the floor

im actually shortening my lwb and not planning on using original wheel wells(pretty banged up).im going to make my own bed floor.i was planning on using the old floor as a template to make the new floor.then marking for the new tubs,cutting it out,and welding the new tubs in.as long as the new tubs are wide enough,should that work?(just dont know how wide they need to yet).i've found some tubs for about $150.00 ,and you can get them in two different widths already assembled from chris alstons chassis works.35"or 43" wide.do you know which width would be best?

If you got pics of that set up PLEASE post them, that is exactly what Im planning on doing with my truck. And I would like to see the finished product.

I may be doing the same mod here, once I finish OverKill's front and move to the rear.
