My Lack of Tire Size Knowledge, and i even did a search Options

[turboinduction]

how much rubber can you stretch on a 7.5 rim. Like 19" x 7.5 Right now i'm hoping for 225 in front and 235 in rear... but i dont know if the rim is big enough.

and STOP all you 19" haters... THEY WILL FIT - ask GT4 and maybe bkolher81

I just want to know about tires, please dont tell me to get different rims thanks!!

When you go to tirerack.com, hit search for tire by size rather than putting in your type of car. Then, put in the exact size you are contemplating. They will give you all the options they sell. After selecting one, just hit the "specs" button. There you will find a column entitled "Measuring Rim Width". According to tirerack:

The measuring rim width is the industry standardized rim width upon which the tire must be mounted in order to confirm it meets its dimensional targets. Because the width of the rim will influence the width of the tire, a standard rim width for every tire size is assigned and must be used. This standardized measuring rim width allows all of the tires produced around the world to meet the same dimensional standards and therefore, be equivalent with regards to their physical size. The measuring rim width is sometimes referred to as the tire's "design rim width".

The assigned measuring rim width changes with the tire size's section width and with the tire size's aspect ratio. As tire section width increases, the measuring rim width increases proportionately in 1/2" increments. Therefore, relatively narrow wheel widths are assigned for smaller tires while wider wheel widths are assigned for larger tires.

Good luck!
