Help me PLEASE stretched tire pros

[CleanA4]

I talked to so many shop and they said that they can try for 30per tire but are not sure it will work.
BTW the tires are discounted and some said its not going to stretch due to it being a older model tires is this true???

FALKENS ST 115 215/35/19 tires, their reason was that it was leaking and that size would not work and then they showed me how it was leaking all around the tire.

I believe that they did use bead sealer.
I spend 140 that at shop and IM PISSED, you guys think Discount tire could do a best job?

use bead sealer...

If they do stretched tires for most cars in Chicago, you'd think they know what they were doing, putting a 215 on a 9.

Maybe it has to do with the fact that 215/35 is not the appropriate size for a 9" wheel and can't be expected to work, even though it usually does?

What brand of tire? What kind of barrel? What was the shop's reason?

So I bought some falken st115 215/35/19 to fit on my 19x9 wheels. I went to a shop in Chicago and they do stretched tires for most car in chicago. They fitted the tires onto the wheels and everything and when they were done mounting them on they showed me that the tires was not sealing up after they fitted the tire onto the wheel. Now my question is it the tires fault for not holding the air or was it the tire shops fault and they didnt really know what they were doing. BTW I saw them using soap to put the tire on.
