Need advice from auto mechanics

[Tikitoi]

This would be for a Toyota Corolla. My tire went flat, and come to find out it wasn't the tire, but it was the valve on the tire. It had somehow began to come off, and that's why it still wasn't holding air when I tried to put it in, even with fix a flat. Anywho, so I was glad that my "trustworthy" auto mechanic didn't just tell me to go and buy a new tire. He manage to get the valve back on there, using some sort of molding stuff (or something like that). But anyway as I am driving on our highway and noticing immediately that as soon as I hit 50 my car is really starting to shake. Never had done this before. So I took it back to him and he says it's because of having 2 different tires on the back. Well it's the same 2 I had before this and it wasn't doing this. He just tells me again, I need to have the same 2 tires on the back. I don't get it. If this wasn't a problem before, why now. He says it's on there good. Any ideas?

(disclaimer, not a mechanic, just lived with and around them.)

So, they took off the tire, messed with the valve, put it back on and now the very same tire is making your car shake?


Did they align the tires after putting it back on?

Was this a reputable shop?

Did they possibly do anything else?

Do they sell tires?

Can you take it somewhere else for another opinion?

My husband who isn't a mechanic but works on cars all the time. Says it sounds like one of the tires is out of balance.
Or if you drove on the tire while it was flat you could have knocked the tire wieght off.

It sounds like to me you might have drove it when it was flat and throw it out of balance

What they said. Take it to a tire shop and have the valve stem fixed properly. Your description of a repair "using some sort of molding stuff (or something like that)". Scare the beejeebers out of me.

Yep, sounds like it's not properly balanced. Have you ever noticed a long metal tab-looking thing-a-ma-jig on the edge the wheel rim? That's a weight, to balance the tire.

the valve should have been replaced for about $5 in parts and whatever labor. mother nature is a bear on exposed rubber and it probably dried up enough to let air out. also bumping it can damage the seal.

they need to unseat the tire, install a new valve stem from the inside, reseat the tire on the rim while inflating it. And then for sure it needs to be rebalanced. which is the first thing to check when a customer says there is a NEW vibration right after tire work has been done!

it is not ideal to use different tires side to side or even front to back, but it does work...
and if they are balanced and round there shoud be no vibrating or bouncing.

Thank you all for the insightful suggestions. I will definitely take it to a tire shop or tire specialist this a.m. I cant believe driving from my place to mechanics which is usually 5 mins going speed limit and even though was going about 5 mph caused this. Unless it occured when it was a bit low the day before. Anywho, will definitely take to have "balance" checked and valve rechecked. I don't mind getting same new tires down the road, but these still have tread on them and hoping to use for as long as I can. Not sure how I ended up with 2 different ones. But I just couldn't understand if it was the same 2 tires, why this happened when he took it apart? Now at least I have a better understanding. But I still can't understand why my mechanic would not have know this to be the possible problem. I swear he is a good reputable mechanic. Just when you think you have a good honest one. Oh well. Again, Thank You.

Maybe the tire was not properly "screwed down" when it was put back on the car. This happened to my daughter and it can be a very dangerous situation.
