my car now vibrates above 75MPH like a freaking washing machine on the spin cycle...

I don't think it's the tires this time, but the alignment or balancing.

either way this sucks and has been a terrible waste of time.

 

I may have spoke too soon. We have a chilly morning here in ATL today, about 45 degrees. And the LS-Z do seem to exhibit some minor flat spotting. Still nothing as bad as the EL42s. And they seem to be far better tires. I also am guessing I need a good balance job. The Firestone dealer only did aold style spin balance, I need to find a good dealer with a Hunter 9700GSP and then get the tires properly balanced. I also let air out this weekend back down to around 33, I will probably push them back up to around 36 which should help the flat spotting. I woudl avoid the EL42 and the LS-Z if you live in a cold climate. I feel I am still ahead so if next winter these LS-Z flat spot and it gets annoying then I'll ditch them then, by then I'll have about 13,000 miles on them anyway.

 

About three weeks ago, EL42's were replaced on my car and the result was that new tires (0804 date code) vibrated from about 45 on up. Took back to dealer, their new wheel balancer had not been calibrated properly. Rebalanced with very slight improvement, but continued to have vibration. Also have some minor flatspotting, but goes away in less than mile. Returned car to dealer today and the loaner I have is 04 TL, serial 36xxx and guess what, it exhibits same vibration as my TL, only sligthly worse. Date code on loaner tires is 0704.

 

What is Consumer Reports' #1 rate all-season high performance tire?

Care to give me the name of the store if I ever need to swap!!

Moody: The tire store I'm trading the EL42's for the Yoko ES100 is owned by a friend of mine's. I'm not too sure he would be willing to take anyone's EL42 & give them 4 brand new ES100's in 255/40/17 for a total of $95. If you are interested, I'm sure he'd want to know how many miles you have on your tires. If interested, let me know & I'll run it by him

 

Need to clarify the statement I made in Post #43 above about the loaner vibration. Took wife out to dinner tonight and after about 5 minutes, vibration cleard up and car drove very smooth at all speeds. When I left the dealership earlier in day, bad vibrations all the way home-about 20 minutes.

 

My TL with a VIN# 36XXX has the EL42's with a date code of 0904 and on the couple of chilly days here in Michigan, flatspotting still occured, however the vibration did go away to, what I consider normal for the car, after about 5-10 minutes of driving. My major dislike for these tires, is the wet weather traction, I am getting wheel spin in 1st and 2nd getting off the line in damp/wet conditions.
