I just had four new BF Goodrich Silvertown H78-15 bias ply tires put on my car a few weeks ago. The tire shop is a block and a half away from me, and it was raining that day, so I just drove the car home and put it away. I finally took it out for a drive today (it finally stopped raining for once). I know that bias ply tires need a while to warm up to get rid of flat spots from sitting, so I drove it around town a few times before I took it out on the road. It vibrates terrribly, to the point that it actually unlatched the hood--I had to pull off the road and close it. I never went over 45mph.
When they balanced the tires, they said there was one that they had alot of trouble with and it took ALOT of weight. They also said that all the tires looked like they were out of round when they were balancing them. The tires were all spun balanced. This shop has been around a long time, and the three brothers that own it have been doing this since the early 60's, so they are not inexperienced young people. I will say that they put all of the weight on the back sides of the rims, as they didn't have Cadillac wheel weights--they threw them out a few years ago!!
My question is this: How can brand new tires be out of round? What do you do if you have one tire that will not balance correctly? If I purchase Cadillac wheel weights and have them balanced again, would it possibly make a difference having weight on the front of the rims AND the back?
I never had this problem with the radials that were on there, it drove smooth and vibration free. I would have thought if I had a bent rim or something, it would have shown up then. I am really hoping that I didn't just spent a bunch of money on tires that I cannot use. I certainly cannot drive the car like it is now. Any ideas, anyone? Thanks for your time, Shawn
