New rims and tires

Damageinc · 12-11-2005, 11:22 PM

Here is a pic of my 2005 Prius with new 10 spoke Primax Sportmax 920's on Kumho tires size 215/50/17.

I've noticed the gas mileage dropped about 4-7 mpg.

Maybe someone else can answer this, I've been up since Sat morning and I can't do the "math" in my head.

Is it possible the overall diameter is bigger/smaller than the stock tires and your mileage reduction is a computational error? By the way, it looks sweet.

Looks like you actually go 67.65 miles when the gage says you go 65 miles according to this calculator converting 185/65/15's to 215/50/17's. That's another 4% of miles which would only be 2 mpg if you're getting 50. Interesting.

Thanks mdmike. I was thinking it was a computer error myself but no way to tell until I use a full tank of gas and see how many miles I get out of it.

Since my new rims and tires and a full tank of gas I went 103 miles when I lost 1 dot from the fule gauge. The computer said I was averaging 42.8 mpg on this tank of gas at the time.

Any thoughts.

Wow! That's sharp looking! It makes it look really sporty! How much did you pay for that setup?

Now I'm wondering if I want a white Prius instead of a black one.

Thanks for the compliments. I really liked the white color or the black even better. The white became available down here in FL after Hurricane Wilma. There were prius' on the lots everywhere. Before the hurricane there was a 3 month wait for any color.

The car was $25K. The rims, tires and tint were under $1,200 total.

Is there a way to adjust the computer to account for the larger tires so that it estimates more accurately?

Damageinc · 12-30-2005, 12:36 AM

I would like to know too.
