I was thinking about putting 235's on my new rims, but I stuck with the 225's. Putting 17's on.

Bigger wheels do change the gear ratio, but if you get lightweight rims and a racing tire you should be ok.

18's are the biggest I've seen on an Alero but I did see a GA with 19's. You always have to remember the sidewall size too. I wouldn't go much below a 40.

I don't know what you are trying to do but my suggestion is to stay away from chrome. Chrome rims are very heavy, they slow you down, and hurt the transmission. If you want the shine, get polished, same shine, less weight.
