I was thinking deep lips would look cool, but I don't know anything about how to buy new wheels and rims. Is there a book you'd recommend that explains the mechanics for a beginner? I didn't have much luck searching on WorldCat or Google. "The Ultimate Wheel & Tire Plus Sizing Guide" is $199 for a digital subscription, and I can't find old editions in print for sale. "Complete Wheel and Tire Buyer's Guide" is fairly old and somewhat expensive as well. TIA!
theres youtube which is free and there are tones of videos to teach you about wheels. What you want to know is fitment. Our Prius's have a bolt pattern of 5x114.3, bore 60mm, offset 38-42. Once you find wheels you like check Alloy Wheel and Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error | Will They Fit
There's a few pictures of Prii with aftermarket wheels for the 5th gen on here to give you an idea and people usually put their specs/offset. If you're buying new, it's fairly easy. Find something in your budget and style you like and how you want it to look; wheels flush to the fender, sticking out, normal. Too far out or too in is bad. Normal to flush should be fine. If used, good luck. It's a pain to get any info from sellers and most don't know where the offset (ET) is stamped on a wheel.
I'm considering.. (pic is a my photoshop of a picture that I found online) I can't post links yet so look up "326717751010511435BP" (Fitment Industries) I just never got wheels before so I don't know if it'll work technically. I think at least the bolt pattern is 5x114.3 for all models
