Shaking From My New Wheels And Tires?

[lessthanzero]

i have a 94 ranger that i have recently added some new tires and wheels too.

I bought Detroit Wheels Cobra R Wheels 16x8 in., 5 x 4.50 in. Bolt Circle, 5.125 in. Backspace

I bought Riken Raptors tires for them

I did not have the skaking before i put in these tires and wheels.

I had to have a machine shop make the wheel stud holes a little bigger for the new wheel studs i had to use. Moroso 3 inch wheel studs. I got that done and put on the tires and wheels. now i am getting this shaking at different speeds that goes away sometimes and comes back other times any ideas would be helpful thanks!!

Something within the wheel/tire combo has to be out of balance if it wasn't there beforehand. There's a chance the tires weren't balanced well. Or it could be related to the fact that you had to get the holes enlarged. I'd take the tires back to the shop first and ask them to re-balance them.

i work at discount tire and sometimes for whatever reason the balancer can be out of calibration or whatever and we get customers coming back with the same problem occasionally. it just happens sometimes. have them road force them if they have a road force machine (they should).

+1 on what both of those guys said. I had the same problem with my old '91 ranger, I took it back and they rebalanced them on the other machine (free of charge) and they never gave me another problem after that.

See if the shop can road force the tires. Our machines at work will tell you were the heavy spot is and how much it is in lbs. You can have a tire with great runout and excessive road force. Usually 35lbs is the max, anything more and you have to 180 the tire and wheel, if that doesnt work then the tire is bad. We see it alot with Toyo MTs cause the casings are so think and heavy on them.
