I was just wondering if Backspacing on a rim is the same as wheel spacers? I need to get rims with 3 3/4" backspacing to fit 33"s. is that the same as getting 3 3/4 inch wheel spacers? (the disks)

If you got a 3.75" spacer you would have more than 3.75" of BS because you would have to add in your wheels BS on top of the spacer. I would try and stay away from spacers that are to big unless you check them. People do run them with no problems but I wouldnt. But I would say try and find some used rims or something if you can or just get a smaller spacer.

different thing, but same concept.

you can use a wheel spacer on a stock rim that has 5.5 inch backspacing to get you to about 4 inch to clear some wider tires. but should be avoided.

just get rims with 3.75 backspacing to be safe. the lower the number the further away from the mounting surface the tires will stick out. therefor clearing suspension components.

But someone else chime in and correct me if Im wrong or has more info about them

if you need 3.75 to fit the tires you should buy rims with 3.75" of BS. for stock rims that originally have 5" of BS a spacer of 1.25" is required to get the 3.75" of BS.

This clears a lot up, thank you very much

Silly question, but can I fit 15" rims on my 99 cherokee? I was looking at my rotors and calipers and it doesn't look like theres a lot of extra room

Finally found out what backspacing is.. thanks

no rdplz

99's came stock with 15's, so yes, they fit. the only reason you should have problems fitting rotors/calipers is if you're going bigger than OEM.

oh okay. Mine came stock with 16's. I'm just making sure so I don't buy new rims and find out they dont fit

no rdplz

Even with 16's, the rotor size is the same so no worries on 15's fitting.

awsome thanks.
