There is no such thing as "tire offset". "Offset" also known as "Backspacing" is found only on wheels.
Each tire has a specific rim width range that it can safely be mounted on. Check the tire manufacturers web site for this info; tire rack also provides this info.

wheels have offsets and this value determines how far in (or out) is the position of the wheel within the wells...and i hope you can see, whether or not you will rub.
tire width is determined by the rim width. you actually get a range of widths that will fit with one best fitting size. using this and the stock tire information, you calculate the aspect ratio and you end up with the tire size. if you don't know anything but know that the tl-s has 215/50/17s, then you are looking at a tire similar to this size. however, the stock tl-s rim width is 6.5 and you want 7s, so maybe go with a wider 225 tire. since the tire is wider, your aspect ratio should be smaller than the 50. as you should see, your new tire will probably be 225/45/17. to determine if it is the right size, you will need to take these numbers and determine the overall rolling diameter and compare it to stock.
now if you get a tire much wider than what is suggested for the rim width (and car), then you will need a even higher offset to prevent rubbing (if any).
