Found some awesome rims! Would they fit?

You might want to flag this post and ask for it to be moved over to : Gen 2 Prius Accessories & Modifications | PriusChat where you may find a proper answer a little bit quicker.

Though not an expert, I'm Pretty sure you are looking for an offset of 45, though there could be a range depending on the tire size and profile desired.

Not sure if this link helps at all, it covers both gen2 and gen3 for the 2009 : Toyota Prius 2009 - Wheel & Tire Sizes, PCD, Offset and Rims specs - Wheel-Size.com

 

5x100 will work on a Gen 2, but 5x114.3 is for a Prius v

 

I have to confess I deal better with owners who bought a Prius for the gas mileage, and are not interested in losing 5 MPG forever.

 

Many have noted on PriusChat that one may lessen MPG when increasing wheel / tire size and weight.

The PriusChat 'search feature' is currently working, though that isn't always the case.

 

My simple non-expert answer would be, yes.

It will also take quite a bit of behind the wheel mileage to regain that $400+ spent on some wheels.

 

Jeff, are you buying them at Tire Rack? If they sell this brand they should be able to tell you or go on line and see if they handle this brand.
I bought a set of wheels there last month and drove over and picked them up.

 

There’s that logic creeping in again.

But it all depends on the owner. I am perfectly happy having the stock rims and hub caps on our 2010:



But they came with the car so cost was included.

 

Even though I appreciate the 16" touring wheels, I would prefer stock 15s and be able to save $$$ on my next set of tires.

And once again the logic creeps in

 

I would personally spend any extra cash on preventative maintenance such as :

• Brake and caliper pin inspection and Lubrication
• Transaxle fluid change
• Inverter coolant change
• Inspect the water pump and change if needed

It’ll help keep your new to you Prius in good sorts.

 

The trouble is old people use too much logic. lol

 

1) This is the biggy. Heavy wheel/tire combos use up more energy than lighter wheel/tire combos.
This is a very exhaustive automotive engineering explanation, every time they claim it will appear to have more mass, know that means MPG will be lower. The Effects of Rotational Inertia on Automotive Acceleration (At the beginning , they give easy rule of thumb guestimates)
2) Low Rolling Resistance tires will be easier to make and purchase in taller profiles.
3) A wider tire will be less aerodynamic than a skinny tire. It is not worrisome at most Prius speeds.

You can combat number 1 by buying forged wheels rather than cast wheels, but forged wheels start at $1500 per wheel, so payback is never going to happen. Tire rack does allow you to select that you want LRR tires in any size.
