tires stick out too much! :/

I just put my new rear cragar SS 15" wheels with 295/50-15 tires and they stick out like 1-2" past the wheel well I want to use these big tires so I don't want to change them. If the wheels had another 1-2" of bs they would be ok and shouldn't hit the leafsprings or shocks. Should I get my rear end shortened or just get new wheels? which would be the cheapest? new wheels are gonna be around $360 and would prefer not to get new ones.

Wheels

Yeah those mud flaps aren't doing much good there!

I think the cheapest route would be new wheels and then sell the ones you have now to someone with a pick up truck. That should off set the price a chunk.

See if you have room to stuff a wheel under there with a different deeper offset . Measure the the edge of those nasty tires and add in the lip of the fender and see what you come up with. Then check out the wheel mfgs to see if you can get what you need .. The brakes will determine the max amount of offset that can be used .. You may also try a camero web site, include the tire size and wheel you have them mounted on. Ask this question there, lots of folks like big fat nasty tire ........ me too, and more then likely have been down this very road .

There is always the load levelers , shocks with springs that can stiffen up the rear to keep down the tire rub ......

Shorting the rear will be expensive and require modifications to accomplish your goal . But would or could mean some tub work ..... very racy . Another option radius the fender and add flares ..... will need to do that at all four corners, widen the front tires to fill the flares , throw on some nice side pipes, lower it a bit. Can you see road racer Sebring style .. mean and nasty ... just some brain storming ...

how to measure offset

Lay your wheel face down on a reasonably smooth surace.
Lay a straight edge across the back of the tire sidewalls.

Make one measurement to the ground. Total width.

Divide by 2 (let's say 10 inches for arguments sake)

Make a second measurement to the mounting surface of the wheel.

If this measurement is exactly half (5" in this case) you have a zero offset.

If the second measurement is 1/4 inch larger (i.e. 5 1/4" or 5.25)
Then you have a 1/4 inch POSITIVE offset.
Or if its a smaller measure then you have a NEGATIVE offset.

This can be done with the tire on or off the wheel. But it must be properly inflated if its on.

Keep in mind that most wheel manufacturers express offset in millimeters.
One inch = 25.4 mm

don't i need more backspacing rather than offset?

and what about mounting the 295/50's onto a 8" wheel instead?

Rule of thumb is
For every 1/2 inch of wheel width change your tire width changes .2 of an inch.

Sorry to say I think those wheels arent going to work.
Cheapest way out is to replace them.

ive seen people put that size wheel on 15x8 wheels before though..my only other option is to get the custom backspacing because the cragar ss don't come with any bigger bs than 4.25

On the classic crager ss you can go up to a 4 1/2 Back space on the 15s and on the 17s you can go as much as 5 1/2 back spacing. It's 4 1/4 back spacing on the 14 inch wheels are yours 14s ?

Backspace and offset are the same thing. A formula to figure out where the tire and wheel will sit in relation to the mounting surface. Just a different way of going about it. I figure BS is like American Standard and offset is like the Metric system, not exactly, but sorta!!
