    the back spacing??

    just got a taco and im saving up for a 3" lift and want to put some 285s on wit 17" wheels... i know most ppl said they had to do some trimming with 285s but most of what i was reading they had 4.5" of back spacing, the wheels im getting have 5.6" of backspacing. does this mean i will probably not have to trim with 285/70/17 or 285/75/17???

    you will probably need to trim, if guys are trimming with 4.5 backspacing, and you have 5.6 backspacing, your wheels will tuck in over an inch more than the 4.5 bs so yea you might be trimming on the inside

    It's not a ton of trimming, and you wont be able to fit 5.6 inches of bs on there with 285, needs to be no higher than 4.5. You can use the same wheels, but you will need spacers for sure.

    4.5" is the ideal backsapacing for the least of amount of trimming. No backspacing will prevent you from having to trim some.

    However, the high backspacing of the wheels you are getting will make it impossible for the tires to fit at all (without wheel spacers) because they will rub the UCA.



    Edit:Wait, this is an old thread.....
