255/80R17 KM2 fit on factory TRD Sport Rims without spacers ?

Hey fellas I'm wanting to run the KM2's in size mentioned. My question is do I have to run wheel spacers to clear my factory UCA's because of the 5.5" backspace. The truck is lifted 3" with ome 886 springs and it has a ARB bumper. Any insight would be helpful. Thanks

 

Lots of good reading on that tire size here: http://www.tacomaworld.com/forum/wheels-tires/155849-255-85-r16-owners-experience.html

 

You shouldn't need spacers. I opted for spacers to give it a wider stance and have had no issues

 

Thanks for the replies. Looks like the majority of the 255's are 16". I believe the 16" factory aluminum rims are less back space (5-5.25)than the 17" trd sport rims offset of 5.5" +30mm. That's why I asked about the 17" if anyone runs them with or without spacers to clear UCA's.
