Im trying to figure ou what is the better way to go. I want a Wide tire and im going with 33's. I want km2's. From what i can tell there are 2 tyoes. the 305 70 r 16's and the 285 70 r 17's. I plan on gettignt the pro comp 8179's as my wheels. So if i go 17 that puts them on a 9 inch wide rim if i go witht he 305's that puts me on a 8 inche rim. I do like the idea of the 17's. What combo do you all think is going to look and perform better. Im going for a ratio of 80 % road Queen 20% Wheeler. Thanks

Keep in mind wide is good. I just cant figure out if the 17 version versus the 16 version makes that big of a diffrence in width.

 

The 305x70x16 tire is a little wider and will show more sidewall. I don't think there is enough difference in the 2 tires to base an performance opinion. This is probably more of what look you are going for. I personally like the look of the 17 better.

 

i do to. the formula is 305 divided 25.4 to get the width and the 305 is 12 and the 285 is 11.2 so i think ill probably jsut go withthe 17's.

 

Hey Rubican !

I'm 07 RG RUBI on SCC.

I have been debating the exact same sizes. The only difference is the 305 70 16 is .1'' taller, about 3/4'' wider and has 1/32 more tread depth than than the 285 70 17.

I have decided to stay with my OEM Rubicon 7.5" 17 wheels and get
the 285 70 17's. I like the look of OEM wheels and BFG's KM2 tire chart says you can run this size on a 7.5" wide wheel, so, for me it's a no brainer.... especially since wheels get all scratched and nicked up from wheeling anyway.

just my

 

You will be happy with either one, you picked the right tire that is for sure. The KM2 is great on and off road.

 

Can't go wrong with either. Very happy with mine.

"285 70 r 17's. I plan on gettignt the pro comp 8179's as my wheels."

Thats the exact set-up i am going with. (unless another rim catches my eye as the 8179's seem very popular)

 

If you're doing as much road driving as you say the 17" should handle better for what your jk will see the most of.

 

I'd go with the 305. Those tires have a very narrow tread width to begin with. One of the N.E guys runs the 285's in that tire. They appear to be about the same width tread as the stock tires. Look at your tread widths online to be sure. Don't just go by section width.

 

i dont understand you m ean they will be about the same width as my stock tires? just 33's?
