Aftermarket Wheel Fitment Guidelines

OK.

So after thinking about your current aftermarket wheels, I believe that they should workout just fine for your application. The only slight concern I have is spreading a 215/45-17 tire over 8", it does fall within the published specs of the tire, but you will need to be VERY careful when parking because you don't want to "curb" your wheels. The up side is the tire gets maximum support, so handling will be at its pinnacle.

A few things:

1) You need 54.1 to 72.6 hub rings, these are cheap & will work perfectly:

2) You will need a new set of 20 lug nuts with a 60 degree seat, your stock lug nuts won't work. I bought these Extended Length (ET) from DP Accessories & their quality is very good. (These are an example, don't buy them) www.amazon.com/gp/product/B00QLINUQQ/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
You shouldn't require "ET" lug nuts because I don't you'll need any type of wheel spacers, so buy the normal non-ET lug nuts. I WOULD CONTACT the wheel manufacturer to see if they recommend a "Tuner" (smaller diameter) lug nut.

"Tuner" (smaller diameter) width 60 degree seat: www.amazon.com/DPAccessories-LCS3A6HC2CH04020-Chrome-12x1-5-Aftermarket/dp/B00JNEBS64/ref=sr_1_1?keywords=DPAccessories+20+Chrome+12x1.5+Closed+End+ET+Spline+Tuner+Lug+Nuts&qid=1563398696&s=automotive&sr=1-1

3) Tires: the DWS-06 is a great tire & I have personally recommended it to friends for years, BUT...
Continental owns General Tire, General Tire came out with the AS-05 about 1 year after the DWS-06, the AS-05 is the same tire as the DWS-06 but with newer updates based on its release date. The General AS-05 is a true winner, not to mention a lot cheaper to buy than the DWS-06. I personally run the AS-05 on our 2013 Prius V & Prime. Conclusion, pick either of these great tires, Don't buy the General Altimax RT43 because it simply won't perform on the same level as the AS-05 or DWS-06.

Recap: Call or Email the wheel manufacturer about the lug hole diameter, the linked lug nuts are 20mm & 22mm's in diameter with your needed 60 degree conical seat. Edit: if you can fit a standard 19mm socket into the lug holes, the 22.1mm lugs will work.

Yes, but first try this because it's pretty simple & effective:

Take off one wheel & add a 3mm tall stack of 12 or 13mm Inside Diameter (ID) washers to 3 out of the 5 lug bolts in a triangle, these washers will simulate your 3mm thick spacers. Then re-mount your wheel & tighten the 3 lug bolts/nuts that have the washers, all you need is a mild (don't kill it) hand/wrench tightening. Now check if you have some clearance, if you get roughly 2 to 3mm's of clearance you should be good to go.

I would buy #1 based on the price.
1) 5x100, 57mm CB, 3mm Spacers, you need 2 sets, ~$16

2) 5x100, 54.1mm CB, 3mm Spacers, you need 2 sets, ~$64

3) Don't forget to buy those hub rings.

When you buy into the RS-R springs, can you please provide the PriusChat community with drop measurements ?

This would only require a few minutes, you would take an accurate measurement from the center of the axle (center cap) up to the fender lip on each wheel while your Prime sits on a flat surface.

^ They Look Great !

I bet they feel awesome compared to the horribly "floaty" OE 195/65-15's, I know my 205/50-17's completely transformed our Prime.

If you ever want to add spacers, I found the perfect 5x100 / 5.2mm hub centric (54.1 to 73.1) spacers. You'd need to buy new ET spline lug nuts to make them work properly, total cost is about ~$105 shipped for both.

You are very welcome.

~2mm's is close, I ran a car a long time ago with about the same clearance, they would slightly touch on harder turns. If you get any noise from your setup, the easiest thing to do is dab some paint on the brake caliper where you think they're touching. Once you establish the exact rubbing spot, hand file about 1mm off the caliper, this should give you what you need in clearance.

Did you get about ~8 turns of lug nut engagement with your new 3mm spacers ?
