A while ago i had two screws in my tires, and i think the rim was warped or damaged.. The wheels have been balance but i have been getting bad vibration at higher speeds..

So i got a wheel rotation today, and now it seems the front end is vibratiging really bad..

Is it easy to fix a damaged rim??

Try getting the car aligned, or new tires. I had the same problem with my 2k1 and i did both and now it rides like a dream.

 

If the tores were removed from the rims to fix the puncture (as they should have been since one shoud NEVER use those 'injectable plugs' on steel-belted radials- the likely problem is that the tires are now out-of-round after the remounting.

More on this: a tire will normally wear to compensate for the normal, slight out-of-roundness a rim will always have...where the rim is 'bigger' the tire will tend to wear more in that area because -and you can picture this- as the tire/rim reaches that point where the out-of-roundness is greater, it exerts a bit more force on the road hence over time the tire wears more in that area. Very slightly, but it happens.

Then, if the tire is dismounted and remounted in not exactly the same spor on the rim, what you may have now is a situation where the most worn spot on the tire is now aligned with the LOWEST part of the rim, really exacerbating the rim's slight out-of-round condition. Capish?

The solution is to take the cat to a shop that has a Hunter 9700 Road Force Analyzer & to have the front wheels 'road force analyzed' This machine acts as a normal balancer except it has a roller that loads the tires/wheels to about 700 lbs and reads the force that any out-of-roundness in the tire/wheel assembly 'pushes back' on that roller with & reads it back to the operator.

I have found that any wheel/tire with anything more than 10-18 lbs of 'road force' imbalance could make a car shimmy...but at least with this machine you will know what the problem is. If the road force is very high, you can ask the tech to deflate the tires, move them (rotate them) on the rim, reinflate & try again and again until you get the tire situated on the rim so that it yields the least amount of 'road force'...then you balance them normally and u should be fine.

If u get anything below 10 lbs of road force, just get the tires re-balanced...if it still shimmys, you have another problem

Good luck, lemme know how it goes

 

Hey Galo,

How do I owe you one? Did i do something special for you??

You have provided very detailed info, and i understand..

Unfortunately i think they plugged a tire without removeing it from the rim..

However the damage seems to be from the rear... This tire had such a deep nail that it went through the tread and out the side wall..

Howver nissan covered teh tire for free (brand new potenza, yah!!! )..

So i doubt its the tire being not round.. howver after the tire rotation i noticed taht now the front shakes more than the rear..

My concern is taht when the tire was flat i had no idea and i think i took a hard bump.. I was just wonderhing how strong of a force do you need to warp the rim??

I hope its just the tires that i need to replace or just balancing because i don't want to waste any cash on my car this year other than winter tires..

Hopefully i will find out when i get my winter rims and tires on.. if its smooth then i know something is wrong, however it might even be suspension... Who knows!

on the timing advance!!


I doubt that the rim could be bent if the tire is'nt damaged but...when u have the wheels off for your winter tires you'll ve lots of time to check these!

haha.. didn't do muhc, just sharin the wealth of knowledge :
