What Is My Cars Problem!!!?????

[spfdfanatic]

The tires on them are used, but with my old wheels, ride was perfect went from 15's to 17's. With the new wheels, every bump in the road makes the car pull left or right, feels very unstable. The wheels are true, and balanced, and the offset is perfect, is there maybe something like a new alignment i should get done, or could it be that the tires were used, and maybe not set up right for the car??? Anyone ever have issues after going to the bigger wheels??

You will always get a rougher ride the bigger the wheel you go with. Not only is the larger wheel making the ride rougher, but you probably have low profile tires on the larger rims which provide less rubber between the rim and the road thus making you feel things a bit harsher. The stability prbablem is probably the result of the low profile tires. They tend to "tramline." (I think that's the correct term) Meaning they follow the road. They'll pull whichever way the road dictates. Do a search and I'm sure you'll come up with a bit more information.

So I guess there is not much i can do about it??? New tires would not help??

Not really much you can do, it's normal with bigger, wider, low profile tires. Make sure your air pressure is correct too.

It shouldnt be that bad..I had 17's on all my cars. The ride is def. more harsh but the car shouldn't feel unstable. Maybe your just not used to it yet.. There could be some worn suspension componets that you feel now cuz of the bigger rims and/or the wear pattern on the tires could also be contributing to it. I would just continue driving on them and see if it improves.

Yeah when I got my 18's I had that problem, and the steering wheel started shaking at high speeds. I just got the wheels high speed balanced and they were good to go. I thought I needed an alignment but the guy at the BMW place could not do it because my rims were not stock. You probably just need to get used to the new ride.

like everyone said your stuck with it. when i went to 18"s my car did the same thing, and still does. but to look at it positively though you will now perform better in the turns now with bigger stiffer wheels and im guessing wider tires so just drive faster and windier roads and you will be happy!!!

Hmm, kinda upsets me because I had such a smooth ride on my 15's, wondering if a little more profile in the tire might help!!!
