Change 20" Wheel to my ZR6

[mikesalim]

Hi All,

Probably a stupid question.

Do I need to lower my ZR6 if I change the wheel to 20" ?

As I found it is quite low already now originally from dealer (using 17")

I want to change to 20" but I don't want it to affect my driving, I'm afraid if the wheel scratch the wheel guard and I don't want it.

Anyone know what is the offset for it?

Thanks before

If you put on 20's with a lower profile tyre won't the overall 'wheel' size remain the same. No need to lower anything ???

Maybe I just misunderstood the question

Danos: Lower profile tyre? Is it mean thinner? Yes, that's what I think I'd do. So you are saying that, if the total size wheel and tyre remain the same, there is no need to lower the spring?

1 more question 20" x 8.5 <-- what is the 8.5? Is it the Offset?

If the wheel is bigger, why would you need to lower the spring? the wheel being bigger means, yes, that the car sits higher but also means the top of the wheel will be closer to the wheel arch. Lowering it will just make it worse. I don't really get your logic.

Just put on 40 inch bro

That's what I think as well, because one of my friend said that, once you change it to 20" it makes your car higher (which doesn't make sense to me) and you need to lower the car (which I don't want)

You wont "need" to lower it. However..... a 20" rim with a low profile tyre will give the illusion that the car is higher than normal. This is because the profile of the rubber is smaller than the actual gap between the wheel and the wheel arch. The car will actually look higher.

On the standard wheels, the tyre profile is larger than the gap so it looks ok.

As a general rule of thumb - the gap between your wheel and wheel arch should always be LESS than the profile of the tyre. The car just looks wrong otherwise.

The lower the profile of the tyre the lower you may have to lower your car to keep it looking balanced.

Look at my car for example. 18" wheels and lowered a little. Makes the wheels look bigger than they are. Most people think they are 19's.

I have a set of 235/35/20 meaning 20 inch rim, and your 8.5 will be the width, same as me.

i put it on, and it looks good, but DEFINATELY NEED LOWERING! anything tat goes above 2 inch of original rim size and low profile tyre(which is a MUST for the car to look good), u will be looking at lowering.

(the rim/tyre was fitting on, and take a look of how it looks like, then taken off again. Reason is, i want to find out how stupid it looks if i dont lower. Reason for not lowering in the end was.. i wan a smooth ride. Where is the rim now? in my garage.. siting there covered..)

U were similar to me when i first started with my camry, thinking increase of 2 inch of rim and NO WAY I WANT lowering. But i ended up buying king spring LOW profile, and 1 month later, bought another SUPER LOW for back, coz it just look stupid if u dont lower the car.

so.. my suggestion(and i think MOST people's suggestion will be LOWERING MATE! coz u r increasing 3 inch!! and somehow, its illegal too, u know that rite? just something to consider.)

U want it for Comfy-ness or for the Looks.

If for the looks, definitely lower it. U just need to drive more careful..

[mikesalim]

Ic Ic...I'd probably go to the wheel store and have it fit and see how it goes before I purchase it (hope they allow it) Otherwise I'll stay on my 17 until it brokes...=D

dannywss: Illegal? to use 20" ? or to lower the car? So, you just keeping your 20" wheel on the garage?

[AcoustiK]

From what I remember comparing my 20" to my stockies there is like 1cm-2cm difference in overall height (its no biggy).

Agree with before its all cosmetic and comfyness.

In Vic, you just need to clear 100mm and its still legal.

[dannywss]

lower the car, must hv 100mm clearance, which is easy(hard to be illegal).

in vic law, if i dont remember wrongly, the increase of rim size is 2 inch more than the ORIGINAL rims.

In this case, original aurion rim will b 17, 17+2, is 19. This is if the po po really hate you, and they found that, i think they will give u a defective sticker hey?

Anyone can correct me if i am wrong.

p/s:i m now selling/swaping(for 19) my rim with someone else, meeting next saturday.

But . . . isn't it +2" for the largest rim for production on the car. Therefore if the TRD has 19" + 2" = 21". The TRD is an Aurion also with 19" rims from production.

I remember on my Mazda 3 it came with 16" but the SP23 had 17" so we could have 19" legally.

[dannywss]

i got pulled over once in friday night along Princess hey, near caufield. The po po just looked at the sticker on my car(for camry, which is near the driver door), where you can find the original rim and tyre specs, and say that i am 2 inch over. I argue for a while(production of kappa at 18) and was not just let go.

so, u can guess wat i receive then. i guess is bcoz i had a little drink, but not over the breath limit(i just smiled).. so he kinda got *****..?

if you are hving good luck, the po po might listen to your reasoning/excuses. If not, i think troubles troubles..

p/s:camry original is just 16, i was driving with 20

Sounds like u got Frked man,

Like those stories where cops fining people for 1cm over the stopping line, and having your arm resting on the window sill of the car, little things to ruin your day, and you smirkng back at him, just made his day.

Typically on a normal situation, they would look at your Tyre load ratings only, thinner tyres mean less rating hence something to pick on....

Going past +2 over the stock rims is debatible because cars come as an stock option e.g. 18's kappas. Another thing the the total diameter of tyres+rims, forgot the number but it is in the lines of 2cm.

Cops can do anything they want really, even if its legal they'll give u the canary and ud be wasting time and money getting a RWC if not a proper EPA/RTA/Vicroads check.

Hey mate what I got told about the legalities about the 2" more rule, was that is a thing of the past. Along as you have the same rolling diameter and the tyre is load rated to that size you will be fine. Spoke to my insurance and they are cool with it. And you usually know if a basic unsurance compay will approved it, ya laughing. But i do live in QLD and cannot speak for other states and their legalities for this ruling.

I have 20" running on a 245/35/20, I could have gone 245/30/20 but it was a Nankang that was approved load rated and the diameter was out, and anyway i cant stand Nankangs for comfort.

So if i were in your situation, i will make my insurance company to have a WRITTEN 'something'/approval that make sure the insurer will insure your car with 20inch rim(even in the WORST accident if to happen). As i always say, never rely on insurance company, read more in this forum and you will find out too why this is the reality. They are doing business too, their TOP-PRIORITY is PROFIT EARNING too.. Hope you get what i mean where..

I am saying from what i experienced from the po po themselves, and i do believe they have more power than my insurance company. Sdy's rules are more strict than Vic and more than Qld, i believe..

Mayb from my look, the po po hates me, and unluckily i look asian too~ mayb that's why huh?

Good luck to all~ By the way, i am putting my 20 inch on too~ and who cares about po po, fuk them!

No need to speak to my insurance coy its legal. Yeah dude, chased up some information. Dont know if it will help your police magnetism problem as it is based on QLD legalities, but might help any QLD readers.

The 2" bigger rule is a load of crap. It was a general rule that the police used for measuring rims and tyres, as tyres back in the day, tyres wouldnt be load rated to accomadate the bigger rim. Now the lower profile tyre can accomadate the bigger rims, it doesnt matter how small your wheels were originally, and how big you go. Below is a link to small modifications of a vehicle i got of the QLD transport site. I also spoke to a repetile wheel dealership and a guy from the QLD transport compliance section and it is confirmed, as long as you have a load rated tyre you are laughing.

http://www.transport.qld.gov.au/resources/...ion_jan05v2.pdf

So if your insurance coy is hassling you or the police, check your load rating compared to the car, I think the Aurion has a load rating of 95, and if your tyres are good your good.

All,

I was thinking to put this on my ZR6, what do you think?

If any of you know where I could get this type of wheel?

Wondering what tyre I should use? and what is the offset as well.

[SecaBoy]

mikesalim:

if you put those rims on your car, i'll dry hump your car...

okay, so maybe i wont , but those rims are porn and when ever i change rims, those rims will DEFINITELY be on the list to look at... 20" in those would look awesome on the aurions!!! :D

[mikesalim]

Yeah...I'm really looking for it at the moment.

I'll tell you once I got some information regarding where to get it =)
