I have a set of 996 Turbo Twist wheels that I plan on fitting with slicks. The wheels currently have 225/40/18 (front) and 295/30/18 (rear) street tires mounted. I want to mount 230/650/18 and 300/650/18 slicks on the rims. Does anyone know if these will fit? How wide can I go on these rims? If I could go as wide as 245 up front I would have a lot more tire options.

Thanks in advance.
