do you guys think there is a strong chance on them rubbing, or its just a "every truck is different" type case?

 

welll, i am running 305/70/17 starting this coming monday, and they are 12 inches wide and will rub the UCA, becasue i dont have enough backspacing on my stock rims, u need at least 4.5 back spacing for a 12.5 tire to not rub, i have done my research on this, so i had to get spacers for my ram, but also i think the year makes a difference too

 

unless someone got the same size tires with a very similar wheel I don't think you are gonna get a real definitive anwser, it's gonna be that close.
While I'm not a huge fan of wheel spacers, my experience is seeing people with lifted 4x4s who tend to play rough.
On a 4x2, I think you'd be just fine if you had to pick some up as long as they are hub centric. Get them on and see if you need them. But you are not going to have much room in there even with the spacers. Almost 35" height and 13" wide is a lot to ask for just a level, even on a 4x4...

 

true...I plan on gettin a BL, just not at the moment...the new rims have a 4.53 backspacing, so, maybe they will be ok, also its not a true 35" tire, they actually measure at 34.6"...I guess we will just have to see if they do rub, I would only need to get spacers up front?

 

What's the offset?

 

offset is -12mm

 

I only have spacers up front and mine don't rub. I think You're good.
