I have a 2011 Ram Sport, I want to put a 4" BDS lift and I would like to keep the original rims, if I go with a 325/60/20 BF Mud, what kind of spacing you guys think I would need so my tires won't rub? I want to go with minimum spacing because I don't like tires sticking out too much....and no bushwackers for me......lot of people say that is better to go with a 35/12.5/20 but when you look at the Nitto Trail grabber the specs are 35.04" high by 13.39" wide on a 10" and the 325/60/20 BF Mud specs are 35.6" high by 13" wide on a 9.5" rim size (Ram OEM wheels are 20"x9")....so I would think they are the same width on the same size rim....just a little taller for for the BF (1/2")

Thanks

 

Same fitment as 3rd Gens

AT least 1.5" spacer. that'll put you at 4.25" BS.

wheel widths are recc'd by manufacturer which is what will put the tire most flat on the ground. You'll get less contact going to a narrower stock rim.
Stock tire width is 10.8". So, I think your pushing it wanting to put a 13.5" tire on there. That 9.5" is MINIMUM wheel width. Doable, but not best scenario.

There's no way a Nitto 12.5 width tire measures out at 13.39. For what I have learned, Most manuf tires listedat 12.5" tires arent even 12.5". 12.0-12.4 for the most part. That measurement is suppose to be tread width(shoulder to shoulder), not overall width which would include the sidewall buldge. Two diff specs.

 

I have a 4" RC lift and 35/12.5/20 Nitto Terra Grapplers ... I have 1/4" spacers all around but I still get a little rub now and then. I'm going to the Trail Grapplers next and will probably up my spacers to at least a 1/2" ... maybe an inch.
