I'm looking at 20" BOSS wheels 315, 316 and 331. All three have a backspace of 6.25. What's the factory BS on an '07 2wd? IF the spacing is different from factory, how far would the BOSS rims stick out past the factory wheels?

Lastly, do you think I could use a 275/55/20 with a McGaughy 2/4 drop or should I stick with 285/50/20. Thanks!!

 

Ok, a search has found my bs to be 5.5 inches. So will a rim with 6.25 of backspacing stick out .75 inches more than the factory rim? Do I need to know the offset to be sure?

 

It depends on how wide they are. You should be able to fit either tire. My 22's are 9.5 inches wide with 6.7 inches of bs and they are just about even with the edge of my front fender flares and slightly tucked in the rear.

 

The rims are 8.5 wide so I should be good to go then. I think I'm gonna go with the 275/55's. A little extra sidewall will help fill the fender gap and I'll only loose about .4" of width. Thanks for the reply, wish you'd of included a side shot of the Expy, like the look of the rims but can't tell too much from the sig shot. Thanks again.

 

I have plenty of pics in my gallary. Just click the little camera icon by my info.

 

Thanks, totally forgot about the link. Nice rims!
