can anyone help me with selecting rim and tire size?

Hi guys, I'm in need of new tires and was thinking of getting rims as well. I run 16s right now and probably would like to stay at that size. I'm interested in finding a size with the most lip I can run without having to roll fenders. I currently have a 3-4 finger gap between tire and fender. My current tire size is 205/45/16. I suck at understanding tire sizing as far as offset. I've searched and there's no ideal size just. I don't want to buy rims and tires then they end up not fitting or I have to modify for them to fit. So if anyone can help it would be greatly appreciated. Thanks in advance.

put your oemm wheel in the first section and put your new specs it'll tell you if you need to modify to clear or not
but if im not wrong you should be able to run 16x7 or 16x7.5 without rolling or pulling offset would be around +45-+48 would fit without rolling.

The first sticky at the top of the page should have all the information you would need. Lots of good info there.
