i'd stick with 35's, unless you put a leveling kit. it's a personal preference, but I like the look of having a good amount of space b/w fender and wheel. Not a fan of stuffing your wheel well with as much tire will fit. again, just a personal preference, and I'm sure either will look good.

 

Hey guys! Just got my 2012 Ram on 12/31/14 and I am getting ready to lift it and put some new tires on it! Getting the 4" Superlift and was going to go with a 305/70R17 on a 17x9 with -6mm offset and 4.5 backspacing... my question is will those wheels work??? I dont want to go to 18s because tires get even more expensive and really wanting to keep to my budget. Thanks in advance guys!

 

You grave digger j/k. Do you have a 4WD or 2WD? 305/70R17 is just under a 34" tire. You should almost be able to fit that on there stock if you have 4WD, if not then that is another stroy. Either way, with a 4" lift you should be able to fit 35"s without an issue. Try either 315/70R17 or just a straight 35/12.5R17.

 

I was trying not to start a new thread haha. Also, that's awesome! I Already have my wheel and tire combo picked out. Going with 305/70R17 BFG KM2s and MB Wheels TKO. It is 4x4 and hopefully they do fit stock because I'm getting my wheels and tires 2 weeks before my lift due to them being on sale next weekend! Saving $400! If not they'll have to sit in the garage till I lift it haha. Thanks a lot for the help!

 

Congrats on the new ram, I love my 09 and it being my first truck, I would never go back to anything else...

 

Hey guys! Got my wheels and tires this week and also got my head and tail lights smoked! Had to get different wheels than originally planned due to being back ordered, but here she is! 305/70R17 BGF KM2s wrapped around Moto Metal 970s
