Two days ago i mounted my old 37X12.5x17 Procomp Xterrain which is close to a 36 inch now on brand new cragar soft 8 wheels 5X5 bolt pattern, 4.5 inches of backspacing. they fit on my 08 2 door Rubi with NO lift just Xenon flares. Front bumper removed along with the rear. My steering wheels shakes left and right beginning at speeds of 60km/h up to 80 km/h, on the highway the vibration comes and goes. Nothing crazy but definetly not good. The garage i went to told me its because my wheels are not hub centric and are only holding by the studs and bolts which gives it movement on the highway, they put dyna beads in the tires and it only made the vibrations worst on the highway! Does anyone know what i can do? I'm going for an alignment tomorrow i hope it fixes the problem

heres a shitty cell phone pic

 

I would recommend finding a shop with a "road force" balancer. It will be able to give you a "dynamic" balnce on your tires. Without this you get a little side-to-side wobble at moderate speeds. The Hunter (model 6700, I believe) road force tire machine can not only do this, but it will tell the tech exactly where to spin your tires on the rim for the most round profile. I have never used the Dynabeads but have heard mixed reviews on their performance.

 

When I got my 37 inch Procomp Extreme All Terrains put on at a local off road shop, they said that it's better to balance them with sand bags. They put a sand bag in each tire and they balance out great. A little vibration when I first take off then the sand evens out and it's perfect. I think that option would work for you.

 

Sands bags? Interesting. Do you have any pics, Dave?
