Will a set of 285/70/17 inch tires fit on stock Rubicon wheels? What lift would you suggest?

 

Yes They Will

As For Lift Not Really Needed But Any Bb Will Do

 

Im actually looking at the same size and would be interested in any info too.
I know teraflex says you need wheel spacers for their 2.5" budget boost, or new rims.

 

Mine have been running fine with a Daystar 1.75 BB. This spring I'm installing a OME 2". Don't know why you'd need spacers due to a lift. Seems like that should be the product of tire width and wheels and the 285/70/17 on Moab wheels don't need spacers.

 

I was thinking about tyres too so I did the sums on the sizes:

Stock: 255/75R17 = 31.8' x 10 (Height x width)

275/70R17 = 31.9 x 10.8

285/70R17 = 32.4 x 11.2

I went with the middle ones (Unfortunately - now I would have gone the bigger one's) and have ordered a Full Traction BB.

 

Here's a conversion tool that I found on procomp's website. It's a handy little tool anyway if you're wondering the size of certain tires.
