just so i understand...

i found a set of 17" trailblazer wheels. pretty cheap.

what years of TB's fit the mazdas?

these are 03's i found.

From the info I found the bolt pattern on those wheels is 6x5. Mazdas are 6x5.5 so they will not bolt up. you could see if you could get them re-drilled but that all depends if the pad is big enough.

Yeah,those won't fit. You could change your bolt patten of your hubs,but if you do that,may as well go 5 bolt and open up a whole new world of better wheel choices.
