Hey Briskoda,

 

I currently have 18*8 ET35 wheels on my 1Z5. In hindsight it makes sense where they would stick out too far on the 2 frontwheels, but I don't understand why they fit perfectly on the 2 back.

 

I have tried to search the interwebs for info on how to take into account what ET size I should go for depending on the size of the wheel.

I tried a danish datasite which just states 

Diameter Fra = Min. diameter. Which I don't get since the stock wheels on mine is 15 inch.

Krydsmål = PCD / Bolt pattern

Inpresning fra = Offset from

Indpresning til = Offset to

Centerhul = Center Bore

Daek bredde = Tire width

Deak Profil = Aspect Ratio

Max Diameter = Well, Max Diameter, which I guess would be maxium size of wheels, which can be fitted, which I know is wrong, since I've seen a 1Z5 rocking 20 inch wheels.

 

The next 2 screenshots are from Wheelsize dot com, which shows different measurements, which confuses me even more.

 

 

So if somebody could make a dummy like me understand the appearant science behind this, I would appreciate it very much, thank you.

 

Cheers

 

ET is the distance between the centre line of the wheel and the face that sits on the hub. As the number increases, the wheel will move effectively move inwards.

 

The largest stock alloy (Neptune) is 7.5Jx18 ET51 with 225/40 r18 tyres. Changing for a 8.0jx18 ET35 will move the rim 10mm away from the suspension strut and also make it stick out 22mm further. This is because the new alloy is ~12mm wider and you're effectively spacing the alloy out by 16mm (ET51 minus ET35).

 

You might want to consider something with ET45 if you want 8.0" wide rims. You can also use something with a larger ET and use spacers to bring the wheel back out.

 

There are plenty of website that allow you to enter the old/new wheel sizes to see what difference it'll make to help you understand this: https://www.willtheyfit.com/

I did know this.

The ET being dependent on the width size of the wheel, I did not know.

Which is why I didn't get willtheyfit at first because it just showed me numbers instead of actually telling me why the ET number differentiate depending the inch width.

Have found a possible solution though so this might not be total disaster afterall, since I found a similar pair with an ET48 compared to the ET35 I currently drive with.
