    Volks are great, main reason I decided not to get TE37SLs is because it was hard to justify for the relative value of the vehicle and the difference in weight vs RPF1s. I have two sets of Volks for my track car, but for a daily it's quite a bit of money. I hope you are able to acquire them, I'd love to see how it looks

    I weighed the stock 16" alloy and it's not as heavy as I was expecting: 18.5 lbs (w/o TPMS sensor or tire)

    If your goal is to reduce weight, you should consider smaller wheels while adjusting the tire size accordingly to maintain the outside diameter of the OEM wheel + tire combo. There are plenty of aftermarket 14 or 15 inch wheels that weigh only 14 lbs - so you'd immediately slash 4.5 lbs per wheel, or 9.5 lbs per axle. You will save additional weight based on tire selection. For example, a 16 inch tire can weigh 19-21 lbs (if you elect to move to 205/55R16 - which seems popular on some iQ forums) whereas a 14 or 15 inch tire is only around 16 lbs.

    Based on my digging around online, these are the recommended tire sizes for an iQ to maintain OEM diameter and not add too much width:

    Stock 16 inch wheels: P175/60R16 which is OEM size (as above, many move to a 205/55R16 but I would never put a 19-21lb tire on an iQ due to the tiny engine)

    15 inch wheels: 185/65R15

    14 inch wheels: 185/70R14

    you have to use the proper lug nuts and hub rings for most of the after market wheels.

CE28 Club Racers are 13 mm, but very costly to ship from the Japanese source I found them at. They were the only ones who were responsive when I asked the weight and lug hole size.

    Since I would really feel bad if the fitment caused rubbing with Tire Rack recommended 195/55R16 size, I was thinking of getting some cheap wheels from America's Tire with the tire size and trying them out first, then going to the ultra light 16x7 ET 42 Club Racers at 5.05 kg.

    imho, the wheel weigh is irrelevant with an 94 hp commuter. perhaps the stock size wheels and tire (volks) might help a bit also.

    i think that is fine. your set up moves the wheels about half inch further out to the fender.

    jfyi, the stock alloy wheels are 16x5 (et45) with 175/60/16 tires. so your setup is quite close to stock.

    Fitment Questions (16x6 ET42 w/ 195/55R16) from Newbie

    Howdy Folks,

    I've recently acquired a 2014 Scion iQ used as an eco-daily, and to be a bit more practical than dailying my now heavily-modified sports car that's getting converted to track-only usage. One of the things I noticed was that the stock wheels are steelies w/ hub caps and that the stock tire size didn't have any really good quality tire options. After a bit of research it looks like I can get forged 1 piece wheel in 16x6 ET42 or ET41 4x100 PCD from Volk (TE37 Sonic and TE37 Sonic SL), and with the extra width should be able to run a 195/55R16 instead of a 175/65R15.

    My main purpose here is to run lighter weight wheels for improved fuel economy and acceleration and get more tire compound options, specifically I plan to run Michelin AS/3+ UHP all-seasons, as these have some of the best wet and dry braking performance available from an all-season tire.

    Anyone know if these tires/wheels will fit? Using generic online wheel fitment calculators, I'm pretty sure they will, but I will be moving things out several mm towards the fender, and I'm not sure how much size flexibility the car has with stock suspension. I don't intend to do any other modifications at this point, just really thorough maintenance.

    Thanks in advance for your assistance.
