im telling you man, i still think its those damn hub centric rings

 

F**K THE HUB CENTRIC RINGS! *rips all my hair out and bangs head on wall*

 

hahahahaha

 

I hate to bring this topic back from the dead but guess what? I got 3 new tires and the steering wheel is still shaking at freeway speeds. The one tire that was kept was the drivers side front and it passed the road force test. I moved that to the back and the steering wheel seems to shake and vibrate a little less at lower speeds. Could the one bad tire in the rear cause the steering wheel to shake at 70mph? Could the tire be rubbing on something? I read around the forum before I bought the 235/40/18s and found that people run them with no problems.

I just got back from a test drive. I put the stock wheels back on and the problem went away. I also tried the stocks on front and nogaros in the rear. I noticed a little bit of vibration in the wheel but it might have been the road, it was nothing obvious. I am not sure if the tire is rubbing against anything and It looks like the tires have lots of clearance and I can even fit my hands into the tight spots when the wheel is turned. It seems extremely unlikely that the new tires I got were deformed as well. The wheels have been tested too and they are true. This damn problem is soo annoying! Could it be the electric steering system?

 

heres what u do, put on the 3 new tires, and put on one stock rim and tire, and see if the vibration is gone..... also, if it was rubbing u would hear it, and u would see marks on ur tire.

 

If the rim is out of round, then the tire is going to fail the road force test. take it to a chevy dealer with a decent balancing machine. They can actually tell you if the rim is out of round.

 

I took it to a chevy dealership and they checked all the rims and they were round. They said the tires were defective though. Come Monday I will get back to trying to figure out this problem , in the meantime I will be driving my other toy since spring has finally arrived, enjoy the pics:







It was a lot easier to make the 315/35/17s fit on the rear of my Formula. I just took a big ass hammer to the inside of the wheel wells and everything fit fine. The wheels are ZR1s 17x11 rear 17x9.5 front. I have a couple of bolt ons installed too.

 

what did you replace them with? more goodyears?

 

Yeah, more goodyears cuz I got the bad ones replaced under warranty.

 

Nice formy ....hammer tubbing ftw Did you have to cut the pinion snubber off too .?..Ive always had to do that with 17x11's with a 50 mm offset .

I think my next step would be skipping the vendor and contacting goodyear directly and try to determain if they possibly have run a bad batch of tires . You may have alot of luck with Tire Rack too trying to get to the root of the problem . There should be julian dates cast into the tire so they can tell when it was made .

 

I did not have to cut the pinion snubber thing off. When I jack the car I do it from the rear end. I know that is not the best thing to do but I am careful and everything fits fine with them still on.

Also, I still have the steering wheel problem after place each nogaro alone on the car with all stock wheels. I am going to try a few more things. Once I finally figure out this damn problem I will let every one know what the hell was wrong.

 

Update for those who wanted to know what the problem was. The new goodyear tires I got were all defective after getting a road force test, that makes 7 bad tires in total I received. The dealership that I had them tested at said these tires were junk and one of them was 39lbs out of balance on the road force balancer. I think goodyear had a bad manufacturing run for some of these tires. I had the wheels tested too and they were in good condition and had no defects.

Again, thanks for everyone's help. I am still surprised that 7 bad tires could find their way to me.

 

those wheels and tires are probably defective.......you should just sell them to me for like $100 lol

they look great on the car bro ...awsome pics !
