I just had some Uniroyal Tiger Paws put on my 2010 Escape. When I first left the shop, they felt great until I hit about 60ish mph. Then I got the bouncing, steering wheel vibration like they hadn't balanced them correctly. So I took it back and they re-balanced. They said two were out .25 and one was out .5. Not really enough to cause that though the bouncing/vibration took a bit longer to occur, more like 65. But oh my gosh, get over 80 and forget about it. It feels unsafe. This is not fixed. Could an out of round tire cause this and should I bring it back to the same tire place (walmart) or at this point should I find a mechanic to look at it? The car has 139k miles on it. An alignment maybe? Though the car does not pull at all to either side. Thank you

  • You definitely need shocks. It's also possible you have a large imbalance in brake rotors or prop shafts. There are repair shops that can test that. They jack up car on a jack with force sensor, then spin the tire externally and measure the system out of balance condition. – zipzit May 23 '17 at 0:18
  • The big question is; did you have this problem BEFORE you bought the new tires? – CharlieRB May 23 '17 at 11:52
  • I did not have this problem before the new tires. I had old mismatched tires before. As a note, I really paid attention this morning and the bouncing is worse up or down hills. Just like an unbalanced or out of round tire. Is there anything else that could cause that? – Rose May 23 '17 at 12:22
  • There are too many things it could be for us to know for sure. I am suspicious of the new tires or mounting. Improper mounting of tire to the rim, the rim to the car and bad tires can cause all types of issues. Wal-Mart has brand name tires made to their own specifications and as cheaply as possible. Since you have taken it back to Wal-Mart and they think nothing is wrong, I would take it to another reputable tire shop, explain what it going on and ask them to evaluate it. You may have to pay them a fee, but they can find the issue. – CharlieRB May 23 '17 at 12:42
  • Thank you. That's exactly what I intend to do this afternoon. I was hoping by getting a brand name tire that I would avoid this instead of those terrible Viva's made just for Walmart. – Rose May 24 '17 at 12:42

Yes out of round tyres can cause this.. I've experienced it the odd time, but normally only with cheaper tyres. I had a couple of tyres a few years ago that made my whole car bounce slightly due to their sort of elliptical shape.

First though.. have the tyre place check that your new tyres are seated on the rims properly, as this can cause the problem your describing if they're not.

An alignment is certainly in order, considering they have been balanced (twice!)

Did you have the same issue with your old tyres?

  • I didn't and they were mismatched, very low on tread tires. This is why I'm leaning towards the tires. – Rose May 23 '17 at 9:58

If the tires are brand new they shouldn't be out of round unless through manufacturer defect or improper storage. If I understand what they said was that your tires were out a 1/4 to 1/2 ounce. Even the small amount of weight when accelerated to highway speeds can generate significant imbalance. If that is the condition on all 4 tires then the resulting constant shifting of forces would make driving difficult. Have them re-balanced at another tire place. Other things to possibly check out are possible suspension issues such as shocks, etc.
