Space savers are normally much larger than the wheels that they temporarily replace

Larger diameter to run a narrow low profile tyre at very high pressure

i had bad ideas including ET-140, 8.5 inches and 195/45's ;D ;D

what about rediculously narrow standard wheels? or wheels with a really low offset?

2CV???

Off set I always get confused......

Low = small number = stick out more?

[Dez]

hmm, I'm yet to encounter a spacesaver of larger diameter than the wheel its sparing for.

most are a couple of inches smaller with a skinny but high profile tyre.
examples-

porsche 944/928, 15" spacesaver with a expanding tyre thats about equvelent to a 90 profile that replaces a 225/60R16

r33 skyline, 125/90R15 to replace a 225+ low pro 17"

what cars have bigger ones?

idea is, the lower the offset, the more the wheel sticks out, the narrower, the more i can band the dish part of the wheel.

basically, if you got some narrow, low offset wheels, you can get maximum dish without needed obscure tyre sizes.

a 3" spacersaver with an ET0 could be made to have 7" of dish and an ET-137, and still be on 195/45's which would have a nice amount of stretch and not cost the earth.

i think thats right anyway

[Dez]

what youre saying isnt correct.

ET is measured between wheel centreline and hub bolt face, so a 3" 0et with the outside banded to 7" would have a ET of -70

the MUCH easier way to do it is take your centre, find a wider wheel with the correct rim bed diameter, and make yourself some re-rims with monster offset.

these are some i did. stock wheel on the right, 15x4 , modded on the left, 15x7 but with about 3" less backspacing.

[SeventyNine]

yeah, great.

an ET of 0 would mean there is 1.5" each side of the centre line.

ET is measured in mm, theres 25mm to an inch, thats 7" + 1.5" in mm whcih is 137.5

that is an easier option ;D id still need to get them banded as there arent any 8.5" steels around do that boston engineering place rerim aswell as band?

yes, but thats not how its measured!!

what you need to do is-


1. find the centreline of the wheel after its banded.
8.5/2= 4.25"

2. minus the part behind the bolt face.
4.25-1.5= 2.75"

3. convert to metric.
2.75x25.4=70mm

the centre line is further out than the bolt face making it a minus ET.

so final figure is -70ET

find some wellers

those rims were dontated by some gawdawful 7x15 8 spoke wellers i bought for a tenner!!
