need 17inch rim guidence
Will 205/45/17 tires on 17 x 7 inch rims with a 38mm cause any suspension problems with the stock lowering springs? (eg. rubbing, hitting the inner fender liner, ect. I've gotten mixed answers so could someone with the knowledge please school me on this.
Thanx |

It might be a tad tight in the front.

You should be fine, your chances of rubbing the inner fender wall would probably fairly high with u-turns and really bad bumps. But 17x7's with 38offset should work fine.
Unless your going for show, i'd recommend 15's or 16's with sticky tires. But if your going for looks, then yeah. The yaris should be able to hold up to _ _x7.5/8 before concerns really start kicking in. But nothing shims, spacers, or camber can't fix. |

I'm putting on 17 because I got a set kickin around.
So with wheel spacers I should be OK all around? What size wheel spacers should I use?? My main concern is if I have a packed car and the wheels start rubbing in the front or the back. |

The only problem that might happen is the on the front wheels rubbing on turns and such. The rears should fit fine.
And if it does rub then you'll prolly only need to kick them out 5mm.

I thought the Yaris was a high offset car?
Why would you ever use spacers? |

The stock wheels are +40mm. The 17's I believe are +50.
You use spacers so you can fit wheels on it that otherwise don't have enough offset to fit.

The lower the offset, the further the wheel sticks out from the car. Using a spacer pushes it even further. It's then less likely to fit. |

If you have the wheels kickin around already ... PUT THEM ON AND TEST FIT! Easiest way to find out!

It is about how far the hub mounting surface is from the centerline of the wheel. A +38 wheel's hub is closer to the brakes than a +50 offset is. This means that their is less space between the hub mounting surface and the brakes on a wheel with a +38 offset then their is on a wheel with a +50 offset. That is the problem here. There might not be enough space for the brakes to fit inside the wheel. A spacer would push the wheel out 5 mm, which should give the brakes enough space to fit inside the wheel. Hopefully though everything will fit inside the wheel so there is no need for a spacer. http://www.tirerack.com/wheels/tech/...jsp?techid=101

a 17x7 with a 50 offset tucks further in than a 17x7 with a 30 offset. 20mm to be exact. I know that offset does not mean how much the wheel sticks out. But it directly affects it. Offset has nothing to do with brake fitment. It is spoke design. However, if your spoke design does not allow it to clear, a spacer would push the face of the wheel further away from the brake. This also effectively changes offset. The size of the hub does not change with offset. So the distance away from the brake caliper does not change. This is why manufacturers like Rays produce wheels with different Face's (same design) in order to facilitate different brakes. They change hub thicknesses to accomodate this. |

SophieSleeps is correct on this one .
Generally the less dish the wheel has, the higher the offset. POSITIVE OFFSET! The more dish it is, the lesser the wheel offset. NEGATIVE OFFSET! Oooh.. and ... Spacers are the work of the devil. Get wheels that fit properly. Ive seen wheel nuts break with spacers, and in a lot of countries they are illegal, unless they are welded to the wheel hub.

I'll back you up and say that in my state, spacers are illegal. It decreases the "bite" that a lugnut has on a wheel stud. It can lead to stud or lugnut failure. What some people do to remedy this is to press in longer studs. If fer some reason people want to do this...Toyota uses 12x1.25 or 12x1.5mm threaded studs. |

It is not too difficult to calculate whether this would work. You take your original wheel width and offset. You take your new width and offset. (Width(new) minus width(old) ) / 2 = the offset difference. (in inches) Convert this to mm. 1 inch = roughly 24.7mm This offset difference is how much further on each side of the rim, you will be protruding compared to the old rim. So if you are concerned with rubbing on the inside...you take the offset of the original wheel and you subtract the offset difference to it. This will give you the offset needed to ensure no rubbing on the inside edge. If you are concerned with rubbing the fender, you would take the offset of the original wheel and add the offset difference. This gives you the offset for the new rim that ensures no rubbing on the outside edge. Example: Old rim is 15x6 with a 40 offset. New rim is 17x7 The offset difference is .5 inch or 12.8 mm. In order for the inside edge of the new rim to sit at the same place as the old one...the new offset would have to be +27mm. If you were concerned about the outside edge of the rim rubbing, then the correct offset of the new rim would be 53mm. Be careful calculating these offsets. In my example, if you had a 17x7 wheel and used a 27 offset, the wheel would literally be pushed outwards towards the fender about 1 inch. In order to really get a good idea of what fits or not, is to know what is borderling rubbing....and then you can base your calculations on that. Use the borderline rubbing specs as your "old wheel" and calculate your new wheel specs from it...giving a buffer area. |
