I have an ES300, with the IS300 rims and H ated performance tires. Unfortunately, I had a flat tire and I took it in to walmart and they refused to fix the flat saying that they don' work on low profiles and if I was to get it repaired it would be unsafe to drive and that I wouldn't be able to drive fast (i.e 90 - 100mph). I would like to ask if the flat on my tires is reapirable. The problem is that I bought the tires from discount tire in Texas and thee is no dicount tire in Maine where I now reside. Does tis mean that every time I have a flat I am gonna end up replacing the whole tire?

Please help

Thanks
