285/75R16 vs 305/70R16

Newbie to the board and wanted to get your thoughts on any concerns with the 285 vs the 305. This is for future reference as I have a '12 JKU Rubi and I am thinking of going from the stock 17's to a 16 and upgrading to a 33.

The 285 is roughly 11.5 inches whereas the 305 is 12.5. Wider will have more contact patch but you will take more of an MPG hit. If you have 4.10 then I doubt you could really even notice the difference between the two. If I had a '12 rubi I'd go with the 305's personally because I think it'd look a bit more aggressive and it'd be better off road but it's really budget and personal preference

Should also add that I have a 6 speed. I was definately leaning toward the 305 because of the wider stance.

Thanks

You are looking at 11.2" wide for the 285 and 12" for the 305. Like kjeeper said, you will take a bit more of a mpg hit with the 305s due to more contact (friction) with the road.

I was torn between the same 2 sizes. What ultimately made me go with the 285 was the fact that it was a load range D tire. The 305 was a load range E, which I was trying to avoid.

Here is what the 285/75/16 will look like on a 4.5" backspaced wheel. Ignore the rabid attack squirrel / recovery device.

Not to show too much ignorance, but why did you want to avoid load range E?

Because they ride like a D10 dozer and are very hard on spines : )

I have 295's that are E's and they ride just fine at the right pressure. Took some trial and error to find the sweet spot, but even the stock C rated tires are rough if you over inflate them.

In looking at DTD, it appears that 33/16's are all load E for the Dura Trac. I'm I reading that correctly? I would either have to go to a 15" (C) or a 17" (D) for a lighter tire.

Probably so. That's why I went with the Rocky Mountains. Well, that and they were $70 less per tire. Lol.

The 16" Duratracs are E's but they arent as heavy as most E Rated Tires.. so they dont tend to run like a typical E rated Tire...
