View Full Version : Wheel / Tire Size Calculator

I was recently tire shopping and playing around with some different rim options. During my research I came across a really good calculator and wanted to share to everyone.


In that calculator you can enter your stock wheel size and then determine if a new combination of rim/tires will fit within the stock specifications and how far out your speedometer will be reading.

I also thought it would be a good idea to list some of the common wheel and tire size information as I was trying to locate that as well during my research.

The information below is based upon my research and is believed to be correct. Please let me know if you think it is different.

5th, 6th, 7th Gen Celica bolt pattern is 5x100.

Stock 5th Gen Celica Rims are 15x6.5, +39 offset. 215/50R15.
Stock 6th Gen Celica Rims are 15x7, +45. 205/55R15.
Stock 7th Gen Celica Rims are 16x6.5, +39 offset. 205/50R16.
