33.8" tires

After tons of research on old posts, Im about to buy 33.8" MTR tires for my 2008 2 door Rubicon. It's got an AEV 2" spacer suspension lift. I plan on mounting my new tires on AEV Pintler wheels that offer more back spacing than the stock wheels.
Wich would fit better, 285/75 R17 or 305/70 R17? Both tires are nearly 34" tall. Anyone see a problem with either of these? It's an expensive purchace, I want to be sure fits!
Thanks,
Nathan

I'm right there with you! I bought duratracs 265 70 17 before my 2.5 teraflex spring lift and now they are too small an i am regretting it! Not so much the duratracs, but the size. I am thinking about selling these tires and getting the sizes you referenced. If I do I will really struggle between duratracs and MTR.

Duratrac is a great tire. So is the MTR. How did you decide on MTR? Please please post pics when done so I can make my choice also.

Also, triple check your overall height. I thought size is 33" flat... Did you do the math or measure them? It would be great if yor right and that may help my decision.

I just went thought this also.. I wanted a tire close to a 34" from the discount tire calculator here is the difference in the two sizes I was looking at.. keeping with a 17" rim.
I ended up buying the Toyo MT's 285/75/17 and should be getting them Friday.

If you view it from a computer and not a mobile device it's a table that shows the difference in sizes of stock 255/75/17 vs 285/75/17 &305/70/17
Thought it might be useful for the op

Thanks for the input everyone. My measurements came from online tire conversion programs that convert metric to standard sizes. I have no first hand knowledge of actual heights. I struggled between the duratrac and mtr, but settled on mtr because I'm looking to get the best traction offroad. It is my daily drier, but when I offroad, I count on my nearly stock (in the suspension department) rubicon to get the job done. I've got a set of wheels and tires off a Sahara that I bought cheep. I use them for long road trips.
Keep your thoughts commit everyone! Unfortunately, it looks like the mtr only comes on the 305 size, which may be to wide. I have no way of knowing.
