Biggest tires without a lift using wheel spacers?

[deedubb]

Hello,

This question is kind of specific and a bit difficult to search through so many posts....

We are putting the 18" Limited wheels on my wife's runner and will be using 1.25" wheel spacers. What is the largest tire we can fit at stock height? She doesn't want it lifted and we are using the wheel spacers ONLY as a cosmetic mod.

Any insight would be appreciated

Thanks
