235/45/17
O.k...
So most everything I've read says to run 235/45/17 if you're going to 235's.
I've talked with a few people now that are running 235/40/17.
It seems there are FAR more tires available at the 40 series size and due to that fact they're easier to find on sale or for better pricing. So my question is... is it bad to run the 40 series or even say just not as good as running the 45?
I ask this because of what I've read/know and what I see/hear. And that I need to get some new tires ASAP.

I believe 235/40-17 is better for WRX & 235/45-17 is better for STi

Some tires run wider (e.g. Advan Neova AD07, & Direzza Sport Z1 Star Spec) than others... I just got Direzza Sport Z1 Star Spec in 235/40-17 which is wider than my current Potenza S-03 PP in 245/40-17!!!

Tire rack recommends 45 series but it seems a lot of folks run 40 series at the 235 width on 17's. Not really concerned about ride quality. I just want what's right for the drive line.
I run a pretty rigid suspension set up so 40 to 45 doesn't make much difference to me. I'm currently running 225/45/17's but I can fit 235's on my car so I figure why no.
If I had 8 inch wheels I'd go 245/40/17 but I don't. I'm running 7.5 inch wheels with a +53 offset.

Since your wheel is 7.5", I'd go w/ 235/40 or even 225/45, IMO.
I was going to get Sumitomo HTR Z III, but I end up getting Dunlop Direzza Sport Z1 Star Spec.
