ok guys i have a 2013 ram1500 i put a 3" leveling kit on and took to are local tire and alignment shop to have it re aligned and put new rims wrapped with 35s, before i had it aligned it had no vibrations or anything didnt pull side to side with just the leveling kit but now with it re aligned and the new wheels and tires it pulls to the right a bit and has a bad vibration at 65-75mph ive had it back to the same shop a few times and told them and they "fix" it then send me on my way and its just as bad

I have a vibration as well at that speed with a 2.5" level kit and tires. Going to try hubcentric rings to see if that fixes the problem although I have my doubts.

I would try a actual offroad truck shop. I had a 2" level on my 13 with no issues up to 90mph. I have a maxtrac 4.5 lift on the 14 I have now and it's good up to 75 but that as far as I am willing to push a set of cougaria mt's. They want to wander a bit after 75.

One thing to remember, when pushing these heavy ass tires outside the wheel arches, they look to grab or track on the road. Its called "tire jerk" and itll drive you crazy for awhile!!! Mine does it after I put hubcentric spacers on it and balanced these tires 3 times, still nothing. What tires and what offset rims did you put on?

what tires are you running on that truck

I measured my wheel hub hole and my hub size. 3 1/8" on the truck hub and 4 1/4" on the wheel. Could very well be my problem. Im ordering rings.

Not an expert, but I've heard of tires that pull. Has something to do with tread pattern. Depending on tires, 35's can be a PIA to balance. Maybe that place is having a hard time dealing with oversized tires? What tires did you go with?
