Backspacing stock SR5 rims
Searched and couldn't find the backspacing of the "twin 4 spoke" SR5 alloy rims. You know - these ones:
Appears the steelies of the same vintage are 5". Have a lead on some rims that are 4-1/8" (meaning they'll stick out farther right?).

Pretty sure they are 3.75 inch backspacing, but it's been awhile since I measured them. I have my set off the 4Runner now and my summer tires on the 7-spoke steelies ON. I'll check the backspacing tomorrow and post.

So 4.125" backspacing will only stick out SLIGHTLY more than stock, right? (BTW - I'm looking at some used 15x7 rims with 34x9.50 SuperSwampers for 'wheeling, so I'm not trying to avoid rubbing problems like the usual backspacing question for wide tires...)

If I did the math right, the tires will stand about 3/8 of an inch wider from the hub. You may not notice any rubbing at the firewall side of the fender at full lock, but you may rub at the top of the fender on full articulation (stuffed). The wheel will not only swing a larger arc turning the wheel lock to lock, but also vertically as the A-arms work. Of course, all of this is also dependent upon what tire profile you choose.

Yeah, tires are an inch taller, but an inch narrower, (34x9.50 vs 33x10.50) so I'm not expecting any clearance issues - but this tells me what to look for - thanks!
