Hey everybody, so i recently bought a set of 20" xxr 521's with Hankook Ventus V12 evo's on them. Immediately as I hit highway speeds, i noticed my steering wheel shaking when i pass 65mph. Assuming that the wheel balance was off, causing the shimmy, I took it in. They balanced it no problem and the wheel weights were adjusted. I am experiencing the same shaking, except its not as bad at 65mph. When i hit 75+ i can feel the same thing as before. What could be the problem? I dont feel as safe driving on the freeway as I did when i had the OEM 17's on, and it brings down the ride quality of my car greatly.

 

did u get an alignment?

 

are the wheels hubcentric? If not you need a hub ring on each of the wheels to reduce the vibrations.

 

^^What he said. Do you have spacers on the car? If not, are the wheels hubcentric? Probably just have to buy some rookie rings for about $30 and will fix the problem.

 

no i dont have spacers, and im not sure if they are hubcentric, i can't find any info on that.

what size rings would i have to get? im having trouble looking for any of that info.

and also, is this going to solve my problem forsure? or just a guess? could my rims be warped/bent or something?

 

If they're not staggered try switching the front to the back and see if you have same problem. If they are staggered, this will not work.

 

I would also like to know this as I am facing the same problem. What size hub rings will we need?

 

they are staggered.

 

Easy solution, get new wheels! But to op check you might be missing the rings in the center of the wheel. Just take one off and check.

 

Those wheels are not hubcentric. You need rings in the fronts to get rid of the vibration. Every set of wheels that i have had that werent hubcentric and i didnt use the rings, i had front end vibration. The moment i put the rings back on the front the vibrations are gone.

 

Yee u need the plastic rings u put that on the hub now ur rims will be concentric= no vibrations. Btw did ur tpms ( tire gauge light) did that come on?

 

XXR's are not hubcentric for Nissan's/Infiniti's. Definitely a hubcentric ring issue. Your wheels are not centered on your hub.

Nissan uses a 66.1mm bore on most of their car wheels. Most aftermarket wheels have a 73.1mm bore and you can use a hubcentric ring to make it whatever size you need. You will likely need a 73.1mm to 66.1mm hubcentric ring. You need to check the XXR's and make sure they have a 73.1mm bore first.

I would use a plastic ring. They are easy to break, but this is actually a good thing. Metal and other materials have a tendency to bond and stick to the wheel due to the heat. With cheap plastic hubcentric rings you can just break them to get them off.

 

There you go^^^^^^^ great post and here's a link to get the rings...

Any vibration in the 60 to 80 mph hour range IS wheel balancing.

What happens when you exceed 80 mph??

Disclaimer:
Asking you to exceed the posted speed limit is not my intention.
This should be done on a closed course with a professional licensed racing driver at the wheel.

 

the vibrations get worse and car feels even more unsteady after 80mph. vibration level depends on which type of roads im on
