I got a quetion about tire size a few months ago i got my 18" rims put on by STS they told me that the only tire size that would fit with out rubbing are 225/35r18. These are a really low profile tire and i've had to replace the rear left tire 2 times, once a month ago and once today due to bubbles . Does anyone know if i could put a larger profile tire on cause these are getting on my nerves

225/40/18 would be the more correct size. However 245/35/18 is the closest to stock diameter that you will get. 235/40/18 also works alright but is a little larger than stock diameter.

Bubbles in the tires? What kind of tires are you running? You get bubbles in the tires from buying cheap tires or driving habits. When you get bigger wheels and less tire you have to relearn your driving skills like dodging potholes, going slow over bumps and railroad tracks, etc. If you hit too much stuff you will bend a rim and/or mess up your tire.
