Ok hopefully yall can help so i have a 91 xj 3.5 in lift has 30x9.5x15 AT tires on it and would some times get a slight rubbing sound almost like hitting those rubble strips on the side of the highway but only at 65 or 70 while cruising but any slower it went away or if i accelerated, now last night i picked up some 32x11.5x15 in the rear and 32x9.5x15 in the front super swampers and now anything over 35 that rubbing and vibration are much worse any ideas? Checked both sets of tires nothing that i can see is rubbing

turns out it was the tires were humming at the same frequency that the truck vibrates at after i took it on the highway realized that its only at 35 its makes the noise then goes away and you only hear the tires hum

 

Why is this is the "Jeep Builds" area??
Just asking.

 

because i am building my jeep and this was a hold up i had
