So, I dont even have my JK yet, but Im someone who likes to plan ahead. The lift Im planning to go w/ is the 2.5" Teraflex. I really like the stock Rubicon wheels. Will 305/70R17s fit on the stock Rubicon wheels w/o rubbing badly?

 

305/70 = 34.8x12 yes it work fine with proper spacers.

 

Therein lies the problem, I will not run spacers. Im sure 1000 people can tell me how theyve had no problems, so just save your speeches, I wont run them.

I wouldnt mind a little rubbing at full lock, but I dont want to have to pull a 6 point turn everytime I want to pull in a parking spot.

Edit: the specific tires Im looking at are the Maxxis Bighorns. Right around 34x12 according to their website.
