does anyone know the appropriate backspacin i need on my rims if i want to run 31 X10.5 15's on my stock runner

 

Did your 4Runner come stock with 16's or 15's? Or do your calipers say "S13WM" on them?

 

came stock with 15 enkei rims on it with sr5 package.....wat does it mean if it says "s13wm" on my calipers

 

Oh, it just means you have the upgraded brake package (which means bigger. Which means 15's won't fit). Sounds like you don't have the upgraded brake system. Have you looked into getting 16's? They are pretty cheap on craigslist (got mine for less than $100) and if you ever plan to upgrade your brakes to Tundra's in the future, you'll need 16's.

 

i was just really trying to stick to 15s....was gonna stick some 31 10.5 15 on them and really didnt want to put much more money in it or i would have it lifted and wat not by now..............they will fit stock rite......just a matter of backspacin on these rims as they sit inward really bad .....mite put spacers on
