Ok folks I'm basically at my wits end. As some of you know, I've gotten new rims and tires. Since the swap over from the stockers, life has had much more vibe to it.
To give everyone the readers digest version, I've got a vibe all throughout the car at higher speeds and it gets worse the faster you go. I also feel the vibe through the steering wheel.
Now for me to address the obvious solutions.
The tires are 255-50ZR-17's on 17x9, 36mm offset Cobra Rims. I'm running the stock bolt pattern.
At anyrate, all of the tires and rims have been "road Force" balanced. When I had them done, they were balanced "very well" according to the tech who balanced them. The road force that each tire/rim assy produced was 5,6,7 and 9 lbs of road force respectively. I've been told that getting the road force below 10lbs is golden.
Now, just to be on the safe side, I've had a proper set of hubcentric rings to put on as well. They seem to work well and do their job.
And just to be sure that I'm not totally crazy, I went to sears and paid $100 for a 250Ft/lb torque wrench.
I installed the hubcentrics and torqued the lugs down properly yesterday. I used the proper "criss-cross, or star" pattern and torqued them down to 105ft/lbs each.
When I drove the car, I noticed that I still had the vibe and if anything it seemed worse at 75mph than it did before....
I'm really stumped. Some possibilities that have been floating around in my head:
Maybe a balancing weight fell off?
Maybe the tires got out of balance really fast due to me driving around without hubcentrics for a few hundred miles?
Maybe this isn't a tire balance issue, but maybe due to me having crappy engine mounts or a driveshaft out of whack?
Maybe this is some kind of suspension or wheel bearing issue?
In addition to all of this, I've noticed that the car now has a penchant to really follow ruts in the road and seems to require alot of correction for every minor thing. Could this be due to alingment specs or is it the punishment that I pay for the lower profile, Z rated tire?
Thanks any and all for your help, hopefully you guys can give me some direction to go in, cause I'm stumped!
