I know stock tires are 225/45/18 but I see people suggesting 245/40/18. So knowing that will 225/40/18 work or 235/40/18 or 235/45/18 etc. What is the range of tires sizes that can fit on the stock rims without drastically affecting the speedo (no more then a few percentages). thanks

I wouldn't recommend going wider then 245 on the OEM 8" wide wheel.
