Okay so ever since i put wheels on my car the ride has been real rough. First my steerging as been shaking then my car started drifting to the right (i need a alignment i know), when i hit a pot hole or something it is really rough, and when i am at lik 35-40 mph the wheels make a really loud sound as if you where in a truck with mudding tires. Do i have the wrong tires?? I need help please!! thanks!!

Low profile tyres give a harsh ride & cause suspension to wear prematurely.

Telling people what tires you have would help. Check the Tire Rack's reviews to see if the brand you have is noted for being loud.

Did you get the wheels balanced? Sounds like they're not properly balanced to me.

i had a feeling. well i wanna get rid of my rims and get some mandrus millenium wheels but i might go back to 18s but i wanna know from the peeps on the forum whats a good size tires to wrap the rims with.

butthead713

i got them balanced 4 months ago. the two front tires are 225/35R19 and they are Dunlops and the back tires are 245/35R19 and that compnay is Diamond Back i think

I had the same issue until i got new wheels/tires. A rim may be dented and you're right about the alignment.

Be glad you don't have a 2005 if you think a harsh ride is unacceptable.

Sorry I couldn't be of more help. Car looks nice, though.

Well there are several things that might cause the problem, starting from balancing and alignment of your wheels, then you would have to check on your shock breakers and springs, the tarods might also cause one sided drift, etc..

ok yeah imma take them off and ride on my stock rims for a little i miss that smooth ride haha.

but thanks guys ill keep you updated on whats up. thanks for yalls help anyways.

BTW anyone know anybody that is selling some 18 or 19 inch mandrus wheels the milleniums.

Are your wheels chrome?

butthead713

Yes. They are 19 inch chrome Zenetti rims i believe they are 8.5 in the front and 9.5 in the back but im not sure exactly i forgot.

e1000

IMO, the combination of heavy chrome wheels, hitting a pot hole and being out of alignment and inexpensive tires are causing your issues.

butthead713

okay thanks, looks like tomorrow im going to take them off and put my stock rims back on. Houston is horrible for low profile tires because we have potholes EVERYWHERE!!

Everything is big in Texas.....even the bloody potholes!!!

Low profile tyres will always compromise comfort. Listen to e1000. Buy decent tyres.

When you have the alignment done get them to adjust castor 1 degree more positive RHS vs LHS to stop drift off to the right. Typically 10.6/9.6 degrees.

Sometime bigger (wheels) are not necessarily better.

The stock OEM for the base car is 16", the option tires were 17" . AMG made some spec rims being 18" (225/40 and 255/35) but needed the rear fenders to be rolled. And you put on 19" which really the car was not designed for at the time. The larger wheels have no lateral give (read as leverage) and does put on added stresses on suspension components and wheel bearings that were not initially thought of or engineered in the design process. You have wheels that are 3" larger in diameter than stock. There will be many on here that say that it is okay to run 19 or even 20, but you give up comfort, noise, feel road imperfections, not forgiving on potholes and expansion joints not to mention increased wear on components and tires. I am not sure how much more performance they will give you. I will take PS2 on 17" than cheap tires on 19" and I will turn circles around you

BTW your rear tires are completely the wrong size as they are a full inch more in overall diameter then what the stock/spec set up. see attached picture

I know it is not a fair comparison but F1 cars which are the best handling cars on the planet use only 13" wheels!

Silver C

Most of the times, bigger wheels are never better..k

e1000

I agree with most of your statements but F1 cars use 13" wheels not because of optimum performance but because of regulations.

With that said, in general, larger wheels will result in a harsher ride. The heavier a wheel and tire combo is, the greater the effect will be. To an extent, a well engineered suspension will attempt to reduce these effects. Aftermarket wheels these days have a wide variety of finishes and manufacturing processes that can affect weight and durability. Cheaper tires will also factor in, they are typically harsher and stiffer, and generally speaking will be louder or become louder after some wear.

Of couse, 19" wheels do look great on a w203.

Well took my rims off a couple days ago and found out 2 of my tires had bubbles on them, I put my stock wheels back on and ohhh did i miss that smooth stock ride. But the car was still drifitng to the right so i had my alignment done and everything is back to normal. So yeah i am going to sell those 19" Zenettis and go back to some 18" possibly Mandrus wheels. But yeah at the end the potholes won the damn battle eff Houston roads if any one come to texas rent an SUV gas is cheaper here and you wont mess those tires up! Thanks for the help.
