The Tyre Thread

[Brando47]

Well I have 205/45R17 atm with a 50mm drop at the front and 30mm drop at the rear with no issues so if you get the prokit you will be fine with pretty much all of them I think.

Edit: @AfterBurner has 20" on his G SRiT as well so when he says this he could comment, think he said he gets minor scrubbing with passengers but not sure on wheel width, arch work he had done etc

That's a good point ay, if your fronts are running fine with a 50mm drop and 616mm diameter tyres, should be able to run about 640mm diameter tyres at least without hassles, which is well above the legal limit already

And holy crap, 20's???? Had to see that on his ride thread haha, looks great! And it's on sportlines!!! He reckons they're either 225 or 235 with 30 aspect ratio, so say best case with 225/30/R20 and he has the 30mm drop on the rears... *get out the calculator* ... 643mm diameter tyres, wouldn't want to go any more than that then without serious guard work!

Just got the thread mention ay, bit slow, lol...

Yeah i get scrubbing, mainly front tho & only have the front guards rolled/slightly pumped (courtesy of 'Sydney Guard Rolling' - iirc his name is Nelson) he did also mention the turbo guards are slightly different than the normal TS styles, ie the inner plastic guard & the return of the lip etc...

Different brands of tyres also have varying edge constructions, ie some will scrub less/more than others... atm im running Hankook's front & still have the original tyres on the rear (came with rims)

Thanks for the insight mate, fairly sure I have enough info now to get some that'll be a safe fit, only have 18's (you're probably the only person I have to say only 18's to haha) but yeah was just trying to find out how much sidewall I could fit under there without too much work

Got a quote today for $205 each fitted, balanced inc GST for some Hankook Ventus Prime 2 215/40/18's at the local today.
Gut decision guys, Kumho, Hankook or Nankang?

[guy 27]

don't even consider nankangs.

also if your lowered you will get scrubbing with a 40 profile. you should ideally be running 35

Still stock at the moment, was thinking maybe the Eibach Prolines if I think it looks like a monster truck but that'd be a while off yet.
Also, I have 8.25" rims to put these tyres on, would that influence anything? Internal rubbing on a TS? Thanks Guy

[guy 27]

whats the offset on the wheels?
you're gonna need to do some mods to get anything wider than 7.5" wide without some scrubbing.

Et42?

[guy 27]

sure the wheels are 8.25" wide? never come across wheels in that sizing.

running a 215/40/18 youre gonna have issues even before lowering if they are 8.5" wide rims. Not only that I wouldn't really recommend stretching a 215 tyre anything past 8"
with a 215/35/18 you should be able to get away with only minor scrubbing before being lowered on the rear and full lock on steering wheel.

if they are 8" you might just get away with it. Will scrub a fair bit at first but once it wears the plastic in the arches away it will be fine. When you lower it you will need to run at least 2deg of camber on the front.
if they are wider than 8" you're gonna have some issues once lowered and will need to modify a few things. Not a major job but a bit of a pain.

Well I've just seen the stamp that says they're 18 x 7.5J. NOOB MUCH.
But if I measure outer rim inside to outside, it's 8.25"?
