Looking for a 914 wheel size ET and tire chart Options

[Dave_Darling]

But offset changes between 15, 16, and 17's and also between widths?

Offset does not necessarily change on different diameter wheels--the diameter has nothing to do with the offset.

If you have a wheel with the same backspacing but a different width, the offset will be different. Or if you have a wheel with the same offset and a different width, the backspacing will be different. That's because offset is measured from the center of the rim, and backspace measured from the inboard lip of the rim.

I am unsure what the offset is on the EMPI's I purchased from the net, but supposedly they came off a 914.

Since EMPIs are all aftermarket rims, measuring is the best idea. The Bug-offset ones will put the wheel very far out in the fender and it will tend to rub the outer fender with anything wider than a 165-width tire.

Ahh..... More to do....

Your back spacing needs to be no more than 4 5/8th....
And if it's less, the wheel sits t farther.

The 6 x 15 I am looking at now have a 112 mm backspace or 4 13/32

Shocks don't make a car stiff.... Springs do. And the stiction from not TRTproperly installed bushings can really contribute to spring rate

The 7R wheel on the chart is basically perfect offset and the reason a real 7r will fit. Of course a real 7r is 1k per a wheel.

The 14 inch windmill that was stock on 6 cars was in my opinion used because it also has perfect offset. It is 2mm different than a 7r and a great fitment. It is also the cheapest fuch you can buy. It is also period correct. It will also give you a smoother ride as most tires available in 14 sizes have a taller sidewall. It also is a "deep" look wheel and cool looking. It does have down sizes. It is the least performance oriented due to the smaller diameter. Smaller width. And lack of tire selection.

All of the 5bolt Fuchs and cookie cutters have the same offset and will fit an undamaged stock car

I am in the process of doint the 5 lug conversion and bought a set of 14" fuchs from Luke M, that were original to the 914/6- came off of his.- Since when i bought my car it had 15" 8-spoke epmi's and i had/have 195/50's on it now, they do not rub-(i also have new springs and sport bilistein shocks), it is really tight and we did roll the fender lip, but that offset is different than the 14" fuchs going on there soon- i will be putting on 195/65's(14) as the offset is correct and will fit a bit better, also a little bit more sidewall, kind of a compromise between the stock tires which were 185/75 i believe. - i think if you get the Fuchs with correct off-set you will have no issue with the 195's., some guys have 205's on narrow body cars.

so,
4 5/8th back spacing is 117.475 MM

You are 5.475 mm away from stock. (sounds like a beetle offset, or in range of one of the beetle aftermarket wheels)
Those wheels will sit out towards the fender by about 5mm more than other wheels...
Pretty darn close.
With a 6 inch wheel and the right size tire, you should be fine.

If you like the wheel, buy them.
You may need to go to a decent small tire store that will work with you to try on some rubber...

ALL 914s are different
ALL 914s are different from one side to the other.

We have put 7 inch wheels on a narrow body non rolled fender car...they fit.

Learning. Thanks.

Scott_In_NH came over today and we worked on my tire rub issue.

The conclusion is that the tire/wheel package I purchased off the internet has VW Back Space.

The Wheels are Empi GT-8's and it looks like they are only made in 15 X 5 1/2 and they have a 30MM Offset and spec a 4 3/8 back space.

The tires are Goodyear 195/60/R15's

We tried Scotts Mahle 5 1/2 J X 15 with an offset of 40mm. He is running 195/65/R15's and with that combo I literally added 1/2 and inch space to the fender.

Looks like Back Space is my friend and I will be doing a new wheel/tire package which is what I wanted to do but now there will be no guessing.

Thanks Once again Scott!

I'm glad I could help John - good to see you (IMG:style_emoticons/default/beerchug.gif)

It is worth noting that John had that 1/2" even with my 195's being about 1/2" wider than his 195's.
