Maximum front/rear tyre width difference for 4motion?

[dylan8]

I had 225/35s on a 19x8.5 et35 and I trashed in the inside of them. rubbed on the coilovers and inside of the guard.
Now run 215/40 on a 18x8.5et30 and its prefect daily specs imo.

Go for the 225 and 235 then, your rear is a lot wider from memory so a bit more stretch should help.

Are your front guards rolled? Just ordered my tyres today and will get them put on on Saturday. Finally! I've had my coilovers and wheels sitting around for nearly 3 months..

nope. stock as a rock.
should have put the coils in already!!
If you want to talk wheels and stuff ill be down melbourne on the w.e

[kapowww]

I didn't want to put my coils on until I sorted out warranty issues with the dealer I bought the car off.. It's still unresolved, but the 3 month warranty is up but now it's in the hands of Consumer Affairs.

Ahh damn I'm busy this weekend.. Gotta get my tyres and service my parents' car. They've been driving their Yaris around HEAPS for over a year without a service. *facepalm* Next time there's a cruise I'll be down for sure!

For what it's worth, when I had the competition controller in my Bora, the rear diff was unhappy with 235/45R17 fronts and 225/45R17 rears. Once I fixed that, I replaced the haldex fluid and filter entirely, just to be safe.

The stock controller's a lot more forgiving as it doesn't engage the rear wheels anywhere near as often, but once engaged, you'll have the same issues I did where the difference in speed between front and rear axles will cause a bit of bind in the diff, which'll make it rather unhappy.

Just want to be sure

Im ordering a set of BBS CH Blacks 18x8.5 for the Bora 4mo

Having say, 235/40 R18 all round will not affect the Haldex in any way?

From my understanding going through the thread only different fronts and rears cause an issue not same all round, is that right?

should be ok in regards to the Haldex

I didn't pay much creed to this topic before (how many r32s o/s have staggered setups etc) ??

I changed my 2 front tyres to brand new toto proxes4 225/40/18 after hitting a pothole. Not immediately, but started getting a loud diff whining noise on trail/decel...
Had organised another 2 tyres and bought them though took a while to get them on.
In the meantime I changed the diff oil at home and it was quieter for Nfew days but then back to the same noise.
Got the new rubber on the rear (so same all round) and went away immediately and haven't had problems since.

I was same 'size' tyre on each brand and haldex blue.

Hth

as far as I know the width of the tyre is irrelevant (as far as haldex is concerned). what you need to make sure is you keep the same rolling diameter.

For example, you can't go 225 wide to 235 wide unless you drop the profile proportionately from say 35 to 30.

You can use this calculatore to confirm rolling diamenters arent varied too much.

Tire Size Calculator - tire & wheel plus sizing

you can also use this to see how much your speedo will be affected.

As far as how much difference in rolling diameter the haldex can tolerate? you will need to research this some more

I read that it can tolerate a 4% difference from what is considered stock, so 225/45 R17

Also, the stud pattern for the 4mo is 5x100?

Just want to know if a rim thats
18x7.5
With a stud pattern of 5x100 and offset of +45 will fit on a 4mo

Thanks
