Wheel and tire fitment

[malbright]

I recently purchased DSE rear quadralink kit and am looking to fit some wheels to what the exact wheel and tire size I am looking for.

Question is does anyone in southern california have a mock up wheel in an 18 or 19 and 11" wide? Somewhat of an odd shape I know.

OR is there a trick way to simulate or mock up a wheel and tire size to check for fitment. I am contemplating on buying their wheel tubs or working on my own depending on what wheel and tire size I like. They built the kit to hold an 18x11 with a 5" bs and a 305/30/18 tire. I do want a slightly bigger tire on it but but I really need to see a size first to be 100% sure.

Any ideas on mock up. Willing to pay or rent a wheel... Haha if someone has one to use.

Please let me know.
