So just got my new Fuel Mud Grippers 33x12.50r20 on 20x10 Fuel Savage D565's, about a week now. Im new to bigger tires and it seems I have vibrations when I hit an uneven road and randomly when driving. I can feel hear it from the front and back, the spare is secured on oem carriers and I installed daystar bump stops so it wont rattle.

Any idea why theres vibration? And also shouldnI get stabilizers to make the ride more comfy or what donyou all suggest? Thanks for the help

 

Your tire pressure might be too high...a contributing factor also could be your combo of 20" rims on 33s

 

thanks.. What PSI should i be then? Im around 35/36 at this time

 

NP Try 28-30 psi...also , search the chalk test method

 

Cant find how to do the chalk test

 

Here ya go!
