Anyone using 225-40-R18 on their 2017 Prius?

Welcome to PC.

Tires: When using a 18x7.5" wheel, a 215/40-18 is the better choice, plus that size tire weighs less which is a good thing.

Coilovers: Roughly ~30mm's sounds reasonable, just remember two basic rules when lowering. 1) The lower you go, the more
negative camber you automatically get. 2) If you lower a coilover system "to much" or close to its maximum lowest setting, they function poorly & handling / ride comfort suffers a lot.

What is the offset (ET) & weight of your Enkei wheels ?

Go with Volk ZE40 attack wheel instead. Much better.

 

Let me get this straight......

You're recommending an ~$800 Each wheel with a poor offset ?

Stock is +43 (??) or so...the volk is +47

 

Stock is ET +40, the Volk ZE40 in a 18x7.5" / 5x100 is ET +48.

Technically ET +48 will work, but that extra ~1/3" offset is moving the wheel & tire Inward toward the suspension strut.

Concerning wheel pricing: Don't get me wrong, I like quality products & expensive items, but at roughly ~$4000 Dollars
for a set of new wheels & tires......I'll pass.

Is there a link for the Tein street basis coilovers for the prime?

 

One of the Priuschat boys?

 

Your Enkei ET 45 wheel will work (picture below), personally I'd mount it and drive it for a little bit. Then I'd reassess the way it looks because maybe you want a ~5mm spacer to push the wheel outward.

5mm spacers that work:
