Hey guys,

I'm finally about to pull the trigger on some new wheels and tires but I just needed some final suggestions or opinions before I spend a lot of money.

After looking at countless wheels and tires for many months I think I finally have it narrowed down. I'm going with the 17x9 Mickey Thompson Sidebiters which I believe are 5" backspace / -1mm offset but several websites have them listed as 5.5" backspace / +12mm offset. Either way I'm set on getting a set of BFG KM2's because I think they best looking & longest tread life mud tire on the market. The only thing I'm not positive on is the size of tire to go with. I've been back and forth between 285/75R17 or 305/70R17. As far as tire specs go they are pretty similar.

285/75R17 - 33.9"x11.3" on 8" wheel

305/70R17 - 33.9"x12.2" on 9" wheel

Does a narrower tire make the tire measurement more narrow or doesn't that make a difference?

I should be placing my orders tomorrow evening and any opinions or suggestions are welcome!

 

Essentially the tires are the same height, the 305 is wider but has a lower Aspect ratio than the 285 the 70 and 75 tell you how tall the tire is in relationship to the width. 75% of 285 or 70% of 305. Go with which ever on you want to rock or which ever one is cheaper.

 

The width of the wheel makes no difference in terms of the tires measurements, in some cases the tire may hang over a narrow rim but you should fine either way you go with these wheels.

 

My orders have been placed!

This is what I ordered:

17x9 - Mickey Thompson Sidebiters



BFGoodrich KM2 305/70R17

 

That tire and wheel combo ought to look great!

 

Thanks PawPaw! I give you little credit on helping me decide on a tire size. I think it will fill the wheel wells nicely!

 

I have always liked those wheels, did you ever figure out what the backspacing is on them? Should look great.

 

I emailed M/T and the tech guy told me they are actually 5" BS / 0mm offset. Which is the same specs as the XD Rockstars. My setup should look like very similar to abarkerr2's.

Tires should be here tomorrow, wheels are a few days behind.
