Newbi needs tire fitment advice please!!!!!

I have a 2012 Jk with 373 gears, Rubicon springs (18/59) and a 1" Terraflex spacer up front to level the jeep.
I would like o put Nitton Terra Grappler tires on it size LT305/70R17 E125R Or 295/70's will either one fit with out rubbing with mostly DD and a little easy off roading during huntin season? I notice the Nitto site says the 295's are taller than the 305's but both rotate the same per mile? TYPO? That ain't possible. CONFUSED!
PLEASE HEP!!!!

Discount Tire Direct's online tire size conversion tool is pretty handy.

Are you sure you weren't comparing a 305/70/17 to a 295/75/17 ? Per DTD's tire size tool, a 305/70/17 is 33.8" in diameter, while a 295/75/17 tire is 34.4" in diameter. Pretty easy for your eyes to wander a bit when looking at tire manufacturers online tire size charts.

Aftermarket wheels or OEM? You know you'll have to buy wheel spacers to use the OEM wheels with 12" wide tires. I have to believe that with aftermarket wheels with the correct offset and you'd have no worries. I'm running 33x12.5/15 tires (32"high) with TF 2" front and 1" rear spring spacers and have plenty of room for wheeling. IIRC while shopping for tires, the Nittos are good tires but on the heavy side compared to other options. With your stock gearing I'd be hesitant to go any larger than 305/70/17 in the Nittos.

Don't make a purchase based on what me or anyone else on here tells you. Call DTD or another volume tire seller and ask them. They know their stuff and are really helpful.

oops forgot to tell ya

I have ProComp Soft 8 rims @ 9.5" wide and 4.5" setback 373 gears Rubicon 18/59 coils Rubicon shocks and a 1" terraflex spacer up front to level a little.

Don't want full level cause I tow a boat at times.
This is how Nitto shows the specs on the tires. they have the 285 and the 295 at different heights but show both with identical revolutions per mile. I ain't a rocket scientist but that don't make sense to me. I really wanna run the 295's or the 305's. think I can with the rubi stuff and the 1" spacer upfront?

Nitto specs as in their site:

LT285/75R17 E121Q 201-030 16.5 33.86 11.30 7.5-(8.0)-9.5
3195 revs per mile

LT295/70R17 D123R 200-430 16.4 33.19 12.13 7.5-(8.5)-10.0
3195 revs per mile

LT305/70R17 E125R 200-900 16.5 33.98 12.36 8.0-(9.0)-9.5
3640 revs per mile

You can run the 305s with 9.5-4.5" BS rims however you might get interference with the rear pinch seams (easy to fix) and add some bump stops to avoid rubbing on the fender liners.
