I recently put 20" Rims on my 2008 Maxima and experince alot of discomfort when breaking and going over 70 mph. I have centering caps which I thought were suppose to lessen the vibration and shaking but they really cause a discomfort when I drive. Any suggestions? Maybe spacers? I've had rims on my other cars and they did not cause discomfort like this when I drove?

 

Hmmm, the wheels were torqued to 80 lb. right?

 

first off there 20 going to be a crapy ride umm have them recheck the front end for inner and out tie rode play and for the brakes gonna suck cause u need to up grade to a biger brake kit man to help stop those 20 inc wheels if you want and you are in sac come to a brake masters ill check out ur front end for you

 

they are not balanced. have them redone at a better shop.

my 20s are barely noticeable over my 18s.

 

+1

 

had a similar problem on my monte carlo u just need to get them balanced really good thats all and then u shouldnt have any problems at all

 

...

 

stupid question but , did you check the rotation of the tires

 

not a stupid questions bc im sure ppl have done that and didnt notice/ know that

 

The question is, are the wheels/tires new or used?

Bad belt in a tire or a slight bend in a rim will have serious vibration.

run your hand over the treads, are they cupped/scalloped?

 

The next question is, are these wheels hub centric?

 

Yup get 'em checked, never had problems with either....

 

tires and rims were brand new and the tires were balanced already at a shop that does my tire jobs. for the breaking i guess yall are right, prolly just need bigger and better breaks then the stock ones. thanks for all the info and advice.
