I have always been partial to the 84-92 Firebird "Hi-Tech" style rims, and just purchased a set of 15x7 for my Aztek.  I also had to purchase some hub adapters to be able to adapt the Aztek bolt pattern to that on the rims.  After having my current P215/70R15 Goodrich Radial TA RWL tires mounted on the new rims, the tires now rub the inner wheel well liners on tight turns in both directions.  So it seems that I will need to replace the front tires.  Given that I prefer the RWL look on the Goodrich Radial TA's, it looks like my options are either P195/60R, P205/60R, P215/60R, or P215/65R to fit these rims.  Does anyone have a recommendation as to which is the largest size I can safely go with and still eliminate the rub?  Any advice would be greatly appreciated.

2003 Gold FWD Aztek - aka "The Warthog"

I don't know about 15" rims, but I'm running 225/65R16 General Altimax HP 100H on my Aztek with no rubbing issues.

I REALLY like these tires.

I went with 225/65R16's to keep the tire diameter the same (so it wouldn't cause the speedometer/odometer to be off).

Again though, you are running 15 inch rims.  Not sure what you can use on those...

...also, I guess you could use shims to move them out a bit.  Not sure how you would go about deciding shim thickness though...

It depends a little on the offset of your wheels. I installed a set of the gold Mille Miglia 16x7 wheels on my 2001, and a 235/70r16 just barely fits. There's literally a mm or so of room between the corner of the  tire and the bottom of the shock tower. You could install spacers to increase that space a bit.

I think the Mille Miglia wheels are 42mm offset. If I could figure out how to insert photos I would.

My problem is that the hub adapters to adapt the Aztek bolt pattern to the Firebird wheels pushed the tires out about an inch and a half, and that has led to the rubbing issue.
