Wheel, tire,offset?

Hello. I am currently switching to 15 inch all around on my fish. I want to lower it just a tiny bit so that the tires fit inside the wheel wells but want as much meat under there as possible. So admittedly I have not searched this whole thread, sooo long. Any suggestions on tire size, offset, etc I am wondering if there is still a good selection at 15, or would it make more sense to go to something bigger? Although I am not a fan of skinny rubber, if the options are limited at 15 inch I may have to? Give me some tire sizes, offset ideas, just want to fill up those big wheel wells.
Thanks

there's still lots of options at 15" but getting exactly what you want size/performance/looks wise at a price you can swallow is a little bit of juggling act, so expect a compromise somewhere.

going to 17 increases tire choices, but may not be the look you want. it's probably a straight across price wise 15~17 on rims and tires, or damn near.

i'm on cop wheels with 215/65's and 235/60's on my 69 and they fill up the wheel wells

fwiw, the car is lowered a bit, 8.75 out back and 73~76 disk front
