    Ahhh, the 4G63. I miss my DSM sometimes. :0) That turbo spooling sound and the BOV whoosh are not something one forgets easily.

    Yunebug your Car looks great, I really like the way the rims look! Scion rims, hun? Good fit, with the right off set? 17", any clearance problems?
    Any way you can post a link or explain how to get the fog lights to work independently from the light switch?
    I can use a general guide, like where to tap into the wires at what fuse, relay, things like that. Doesn't have to be to technical for me.
    Thank you for your post, time and effort.

    I followed Darrell's guide, of course.

    Wow! Looks great!

    Let us all know if your fuel consumption is affected at all by your new tires & rims...

    It's not a question of if, it's how much. lol

    Everyone that has installed the Scion wheels has noticed a large MPG drop. If they claim otherwise I would seriously question their measuring practices. :) They are simply too heavy not to induce a negative change and that doesn't even take into consideration the weight of the tires or their increased roling resistance.

    Car looks good man. :)

    Thanks for the replies. :0)

    I wonder how much of the driver input is associated with the actual drop in MPG? I, of course, had the urge and a short burst of the lead foot after these were put on. The better traction and handling makes me *want* to drive it more aggressively.

    There is no question that there is a drop in MPG. Simply because they are heavier and wider than the stock. But let's look at the numbers:


    Prius stock 15" wheels - 14 lbs each

    Goodyear Integrity 185/65/15 tires - 17 lbs each
    Tire Specs for Goodyear Integrity

    Total weight per wheel = 31 lbs



    Scion stock 17' wheels - 21 lbs each
    ScionLife View topic - OFFICIAL 2008 Scion tC coupe stock wheel weight

    General Exclaim UHP 215/45/17 tires - 18 lbs each
    Tire Specs for General Exclaim UHP

    Total weight per wheel = 39 lbs



    We're talking an increase of 8 pounds per wheel, 32 pounds all around in rotational mass. I do not quite know for sure how the unsprung weight differs from the onboard (spring supported) weight, but 32 pounds isn't much in onboard weight (two 16 lbs bowling balls).

    Could the Scion TC wheels and new tires really have that drastic reduction in MPG? I think the blame (for the lack of a better word) goes to the driver.


    I'm also being negligent of the wider tires (185mm vs 215mm), but even with rolling resistance factored in, I think the negative fluctuations in MPG is more significantly attributed to the driver.



    I'm driving very conservatively. We'll see what happens to my MPG. :0)

    That color looks like it would be invisible at dusk.

    Having tested this myself numerous times I conclude it is not the driver, at least not in my case. :). It is the actual weight and rolling resistance increase that causes the drop in MPG. Keep in mine that I own a set of 17" Centerlines w/ Kumho Ecstas 215/45/17 (combo = 37lbs). I've tried my best to justify using them but the last 3 times I've swapped them onto the car and tried to drive normal and even hypermile, I end up with consistantly 4-6mpg less than I do with the Integritys in similar weather and routes. :(

    I'm not trying to take away from your car or your post. Someone asked and I wanted them to know that there is indeed a consequence to upgrading to heavier wheel/tire combos. :)

    I have the same experience as F8L. I have a lighter rim but UHP summer tires. They look awesome but I can't stealth that long as the speed drops quicker. Accelerating on battery power is slower and I can not enjoy over 50+mpg as I get less. I am now on stock rim with Nokian I3s.

    Once in a while when I want to change the look, I put 17" back on just for the show and handling.

    Ah. The veterans speak . :) The MPG is definitely scientific, I guess.

    The handling is definitely better, though. It's nice to confidently turn those corners. :)

    I can't argue that! Handling is a lot better with the 17"s. :)

    Keep in mind that adding 32 pounds of wheel weight is much different than putting two bowling balls in the cargo area. With the wheels a great majority of the weight is away from the hub, thus the rotational inertia of the wheel is greatly increased. Since they also have a larger diameter than the stock wheels, the extra mass is moved even farther away from center.

    It certainly won't knock 25% off of your mpg, but a noticeable loss is assured.
