Without a doubt, yes. Those rings keep the wheels center on the hub. You will notice that most rims are NOT hub centric which means they sit wherever you tighten them up at on the wheel. Using the rings places the rim exactly in the middle so you wont get any hoping going down the road. They are a must have.

 

so i am actually having that problem now. i got them installed at a dealer. balanced and aligned today and my truck is still wobbling. did the tires just not balance?? and im going to ask about the center caps tomorrow and see if they installed mine

 

well i checked my rims they have the rings so i guess the tires didnt balance.

 

my truck feels like its on rails ever since I put my Nittos and monsters on. You should definitely take it back in and have them check it out.

 

If you get discount to give you the rings they might not be the right size, as that is what happened to me. The rings must fit exactly and have no space between the hub and the ring and the rim. The ring should not have any play in it for it to center the rim correctly.

 

I took my wheels off on Sunday and pull the "rings" on becuase I didnt have them on before. I didnt have any hoping or anything before but now I do??????

thats very strange. did your kit come with the red and green ones?? not sure but i believe the green ones are for the f150

 

My kit came with a black set and a green set - i put on the green set and now I have a weird vibration...

 

There is no way the rings can hinder the performance of the balancing. Ask any major shop about them. They actually perfectly center the rim on the axle and hub. If you have any vibration its due to a bad rim, tire, or balance. I have had several sets put on several of my trucks and if I didnt use the rings sometimes the shaking or hopping would happen until the rings centered the rim on the hub. If you are having that problem you need to have them check each rim for being bent or a tire having more rubber on part of the tire and out of round. A good shop (not discounttire) a true truck shop that knows what they are doing will know how to tell you what is bad. The shop I go to actually put the truck in gear and watches the wheels as they turn to make sure they are smooth visually and there is not much movement. Not all tires or rims are perfect so the key is to make sure when you buy them they are tested first on the vehicle moving. You will be able yourself to see the difference between all 4 of them and how much they are going to wobble or not while they are in the air on a lift 1 foot off the gound. You can even do it yourself in your garage on 4 jackstands and put it in gear and let off the brake, get out of the truck and watch them turn to see which one is giving you h e l l
