Wheels for Prius

Since performance is an infrequently used adjective with respect to Prius, you should be ok

 

a fewquestions-

first, why would you ever have different diameter tires on the front/back of ANY car other than a dedicated quarter mile drag car?

second- why do you want to have that big of a tire on a prius? a 255 tire is way overkill, particularly on the non-drive wheels.

third- are yo utalking about wanting to find rims that will mount this specific tire size? or use the rims that are currently on your BMW on your prius? i doubt the bolt patterns and rim offset will match so they won't fit anyway.


lastly, not a question but a suggestion- there's a thread called modded priuses (or modified priuses, something liek that) that shows a number of prii with aftermarket rims. start there.

 

where to start..

115 is the largest i would go with a prius (that's what i have)

larger on the rear will ride wrong unless you change the toe on the wheel.

larger on the front makes the car rock back and forth.. it's really not all too great. since your tires will have more cushion than me, you may like the ride.


I would say try it. it may or may not work. the offset you need for those tires would make them rub on the outer fenders. so you may get bump interference.

If all works out well, post pics and comments. I'm curious

i've seen people use 18"s

 

Some on this forum have reported a loss of mileage with different - wider - tires. It makes sense. A wider tread means more tire on the road, means more drag, means lower mileage.

If you want to spoof your ride, go for it. If you're looking to spoof your ride and maintain performance, forget it.

 

Do the bolts pattern and spacing even match?
I believe Prius is using 5x100, not sure about BMW's wheels....that's Euro vs Japan spec here.

 

My understanding from reading the forums is that you are very likely to take a performance hit in the area of fuel economy (mpgs). Unless I'm mistaken, I think even the Touring model's 16" rims reduce FE a small degree because they are slightly heavier. Unless you have a comparable lightweight rim/tire combo with similar rolling resistance tires, you are likely to see a drop. That said ... gas prices are on a serious decline right now, so if the drop is 5 mpg and you'd rather have nicer rims ...

 

No dice - offsets are totally different. I believe the BCDs are different also

(and the tires would be way too large, anyway)

 

I would be curious too. I'd really like to see a Prius with rolled fenders.
