Cheers mate
The tyres im running at the mo are 235/45 17 and i have room to spare
The new ones are 245/35/18 slightly wider but smaller in total DIA
Here's a handy link

Guys would that be the same for the TC's
or are the wheel arches completely different.
or are the wheel arches completely different.
The same for TC's. The rear door frame impinges on the wheel arch. It limits the wheel diameter. Even 225/60 13's rub on the rear door area on TE cortinas unless you can change the offset. This most important fact is that the car was designed in 1969, and was designed around 580 mm tall cross-plies. The Aussie design team ended up with 615mm 185/70 14 tyres on the S-Pack wheels GASSED250 has on his TE. This made the car ride and handle much better, but the hight limits width to 195/65 14's unless you do some clearnace mods.
The other option is to go for Saab 900 or Ford Mondeo 15" style wheels with taller tyres, and trade off the width to 215 mm max. The only other option is mini-tubes or very mildly rolled guards. It's very easy to make the old Cort look pretty huckery if you do it wrong, but I've seen one wild 14X7" rimmed 12 slot V8 TD look like a million bucks with 225/50 14's. You either go for squatt 580 mm tall donuts for width, or narrow donuts for height and wheel travel.
The Koeran Hyundai Stella stuff never got out of the old Eurpoean Cortina sizes, so it's a dead loss.
If you go for a taller tyre, you fix the poor ride Cortinas suffer. A 185 /82 13 tyre rides so much better than a 185/70 13 tyre becasue there is a 44 mm height difference. The ride height goes up 22 mm, and you can then use lower springs without problems.
We'd all like 15*6.5 J Fairmont alloys, but the tyre size is limited to 225/50 15 tyres, and then you have to go for Falcon or bullrt proof Hilux 5-stud brakes and axles to make it fit.

Current mod 200SX and R31 Skyline share the same offset as the AU

So in my TC I should be able to run 245/35-18 in the rear and say 215/35-18 in the front?
Then 245/40-17 in rear and 215/40-17 front should be ok too. According to the program.
With these sizes will I still be able to lower my car to the lowest legal height in Victoria without scrubbing?
And why is the rolling diameter different on different width (but same height) tyres on that program? I would have thought it would be the height only that affected the diameter.

Heres some pics of the clearence that i have
Rims are 17x7 with 245/45 tyres
There is a good inch between the tyre and the outer wheel arch
the guards have been rolled and the car has been dropped about 1 1/2"
tyres do not rub on any part of the wheel well even with people in the back

The British and Euro TC, TD, TE, and TF were designed around 185/70 13 tyres, only 580 mm tall. The Aussie TE and TF was re-engineered for taller tyres, up to 185/70 14'S on the S-pack rims that Gassed260 has. This is 615 mm unloaded. Ford Oz did it to improve ride and handling.The taller tyre improves ride by brideging the pot hole or rough surface, while imprving the contact area . The Euro spec TC suspension has very little suspension travel, and doesn't run taller tyres. It will ride one heck of a lot better with taller hides, though!. The tallest I've run is 618 mm in the form of the 185/82 13's on my old TD, and it rode a lot better.
My friend Rich runs 225/60 13's on his TE, and the rear wheel arch rubs with 13*7 rims. As you go to a taller:-
+1 (14x 5.5 J factory S pack),
+2 (15x6.5J Falcon XH-XG Outback, Longreach/ED-EF, or Saab 900T),
+3 (16" rims),
+4 (17" rim),
+5 (18" rim)
the maximum width you can run drops. The best option is the one that suits you.
Do a web search on the German/South American 'Ford Taunus'. (The car the Cortina is based on) The Germans are putting huge wheels in the confines of the TC,TD, TE and TF versions of theirs.
You may have to limit roll stiffness, chop up roller skate wheels to make suspension bushes, and experiment with 30 mm anti-roll bars to stop wheel rub, but hey, if its gotta be radical, whats a little spinal compression?
<<<<This Euro TF Cortina with a V6 runs the earlier TC spec suspension and frame. See the big 16's on it? Yummy!
For more information on the old TC based suspension system , check this.
This guy is using a set of 205 and 295's. A full chassis clip is detailed on pages 1, 2 and 3 for a British TE station wagon, which is just a TC Cortina, really.

I will possibly be using a disc brake 3.23 lsd diff from an ed xr 6? Will this change my offset? Will I be able to fit in higher/wider wheels then?
I dont really mind as much about the width (with in reason) but I really want to go 18" for the front and back wheels. Will I be able to?
What are the widest rear tyres, and fronts for that matter, that will fit a TC Cortina.
(Side note; Ill be running the hoppers stoppers au III brake conversion so Ill have an AU offset at the front.)
And car is to be lowered to lowest legal height in Victoria too.
No one will have the exact answer, unless they have done it before, but an educated guess will be good enough.
thanks guys.

Yeah its a little bit expensive, but I am prepared to pay it for what you get. I recon its worth it. Cant tell for sure until after its done though. But you would think the brakes would be WAY better than crappy stock.

Dude if you go the hopper stoppers kit dont go the AU one the offset is fâ„¢cked and the AU was shit so they didnt make many after market wheels for the offset especially in 18's unless you go factory whells like a TE or TS 50 or even the new GT or XR's.
Goodluck let us know how shes pulls up cheers Steve

S#!T I didnt know that. I thought you could put any 5 stud falcon wheel on. Do they do a different kit that doesnt use the AU offset but still has the falcon 5 stud?
So there is no way I can use the same wheels if the front wheels offset are AU and the rear is ED xr 6?
This would be real bad news for me.
thanks

Thek, no if you have a true AU offset at the front youll need 2 different offsets 1 for front and 1 for back. You can order 2 wheels at one offset and the other 2 to suit the other end.
The rear wheels will be fine with the ED offset as long as you shorten your 9 inch/falcon diff to suit.
Not sure if hopper stoppers do any other brake upgrade for a TC/TD or at any other offset as its not a legal requirement but i guess they would.
An AU offset is 6 positive where as a ED offset is bout 36/38 positive so an AU wheel on the rear of your car would sit 30mm closer to the inside of the wheel arch.
The front is a different story again... if the AU hopper stoppers kit sits out far enough on a TC then an AU offset would be fine, if it sits about middle of the wheel arch then an AU offset wouldn't fit as it will sit 30 mm inwards on the car, you would then go an earlier model falcon offset....pre AU Falcon.
Best thing to do is find out from Hoppers where the hub will end up on the front of a TC, they should be able to tell you what offset to use anyway as they have probally done the upgrades on TC's before. Thanks Steve

I fitted an 8" to my old te that was wider than the STd diff I had to use AU rims to clear the arches
My tyre guy said that 200sx shares the same offset and pcd as the AU
and theres heaps of after market rims that will fit
I have some 265/35/18 tyres that I will be dummy fitting to the rear so i can work out what offset I need
I will take some pix with them in the guards

Hey I just ran the sizes through the tyre size calc and guess what
The 235/45/17 are exactly the same in hight as the 265/35/18
I think there gonna fit

Firstly what is offset? Is it the angle at which the wheel is affixed to the studs or is it something else?
The hoppers au3 kit for tc cortys comes with an au offset. They say this is the best because the hub face is in the same place as with the standard 4 stud cortina.
I dont know what diff I am going to run yet. I want about 300rwkw in the end so I am thinkin I will need a 9". Can you get any 9" with discs on em already. I really want discs all round. Will this be costly to graft on to a tc?
If you cant get a 9" with discs, can an ed xr6 lsd handle 300rwkw? I am thinking not, but what do you guys think?
The reason I am so set on the ed xr6 lsd is because a guy i have spoken to had this put on his td and it was realatively cheap and easy.
yep, gassed260 it would be good to see the pics of your guard clearances on the new wheels. What type of corty do you have? Is it a te?
the diff thing I need to sort out asap as I cant get any wheels before I do.
thanks

Does this mean that I can use AU offet wheels on the ED offset rear hubs as long as when I get the axles shortened I allow for the au offset?
I am new to this offset stuff so any help or education is appreciated.
before yesterday I just thought you had to match the studs up and your were cruising. grrrrr........... nothing is ever easy.
