Wanna run them when I do the 3" lift, just think I might need a 1" spacer. The BS is 4 3/4 or 5", can't really remember. I was thinking they might rub the UCA's without it. Any opinions???

 

If the 17" Tundra wheels have a +15 offset, then it is the same as the stock N185L 4Runner wheels. Rubbing on the UCAs will be dependent on the tires you'll be running. Different tire brands have varying tire section widths even if they're of the same size. so best if you do a trial fit first.

 

I run 285/70R17 with the Tundra wheels and I do use a spacer although it is just a 1/4inch (not the thread on type). Without the spacer you will rub on the UCA when flexing.

 

Ok. That's exactly what I wanted to know. Thanks
