wheel offset

[kirk10]

hi

i have a atlas axle on my mk1 escort with bubble arches

and need to no what offset wheels i need ?

i have got from the half shaft wheel face

4 inches at the front from face

6 inches at the rear of face

 

so need 10 inch wide wheels max overall width can be narrower tho

[Rick]

you wont get 10's under there chief

 

remember you got the width of the tyre aswell

[kirk10]

yeah thats why i said max 10 inches

15x8s would be ok with me can any 1 work out what off set please

ive got 11 inches to play with but would be tight at that

just need to no what wheels and width would be best

and what off set i need

yours looked nice under there rick but would have to roll the arch lip lol

[kirk10]

think ive sussed it out

if i go for 8x15s

i would be best getting an et00

or at most et10

bump

[you'll get 10s on that]

Hi

 

In relation to the dimensions you provided you can havea 9" wheel with an offset of ET25 (I;ll explain....9" wheel with et0 will give you 5" inboard and 5" outboard so to bias it 1" inboard you need to move the wheel 25.4mm inwards)

 

In relation to how much tyre room you have that will depend on the sectional width of your desided tyre. Once you have that you can use your offset value to determine how that tyre width is split.

 

but you say you have 11" so you could well get a 10" wheel on that....if you have allowed the extra inch split betwwen the outside and the inside then the offset will remain the same and you need a 10" wheel with an offset of ET25 ( that would have a backspace dimension of 6.5")

 

Once you have your tyre spec post it and I will clarify

[kirk10]

ok thanks mate made it a bit clearer for me

think i will only go for an 8 inch wheel to be honest as i want to have fun in it

and not brake anything with to much grip

 

just looking to see what wheels i can go for now with that offset you have said

et00 upto et25

[kirk10]

these should fit ok then

9x15 et 12

or these at 8x15 et oo

but it says group 4 wheels would i need diferant studs and what ever to fit those

[Rick]

i might get a pair of those wider ones for the back of mine. il sell you my other two if you need smaller ones for your front

[kirk10]

what offset were yours rick that i tried on the rear of mine

[kevmk2]

My mate Icky has 8x15 compomotives on his tarmac arched mk2 and they are ET00 offset, but he has a shortened atlas on it, which means we had to use a small spacer on it, but he has room for a 9x15

Using 225.45.15 tyres

[Rick]

what offset were yours rick that i tried on the rear of mine

no idea but theyd be perfect for your fronts

[kirk10]

yes deffo intrested in the 2 mate then could go halfs on a set of 4 on ebay if you wanted

just need to make sure they will fit tho

go and measure or see what offset they are on yours

as they was tight on the rear of mine with the atlas

[Rick]

you need the more dish at the back that font mine are about half n half. no idea what numbers mean il have a look later when im there

[you'll get 10s on that]

Hi Again

 

The 9" Compos on Bay are ET-12.....That's a NO NO based on the dimensions you provided

 

 

These wheels will be approx 10" overall and will extend out from the mounting face 5.5" Beware. If you have metric studs you can get conversion wheelnuts to suit Grp4 wheels direct from Compomotive

 

In relation to the 8" wheels at ET0 they will have 4.5" of wheel outboard.....Hope that helps

[kirk10]

so these should fit then but wont have much dish to them

8" wheels at ET0 they will have 4.5" of wheel outboard

Hi Again

 

If you have the 4.5" space you#ll be OK

 

Good luck
