Just wondering how 20 inch rims (20/30/225) would work on a Honda Civic 2007 VTi 1.8 which came OEM with 15/195/65?

I've heard heaps of people on this forum who claim to have upgraded to this and claim its no trouble but I'm wondering how the smoothness of the ride would become? E.g. going over speedbumps, potholes and also the possible problem of rims bending and denting over potholes. I'm also wondering about if the 1.8 litre engine would become damaged from lugging the heavy 20s around, or even if it's capable opf pushing 20s. Anyone wanna shed some feedback?

... waste of time putting 20's on a civic. but thats in my opinion so u dont have to go by it cos i prefer smaller wheels..

if u do.. say hello to the joys of scrubbing, no turning circle, and an uncomfy/unsmooth ride, and looking gay.

speedbumps - depends on what suspension u got?? best to slow down for them n e hows.. unless u got a 4wd
potholes - everyone goes over them no matter what.. and it always hurts the poor car..
rims bending - depends on how hard and how large or deep the pot hole is? and how small your tyre is and the angle u hit the pothole..

in answer to your question about can it drive normally.. yes it will drive but very slowly.. its just like carrying 4 people in your car.. therefore, more petrol needed to move the car which equals less kms per tank.

but still its up to u .. your car.. dont let n e one influence u, in the end its all up to u

Hi Sabretooth,

I have just put 225\35\19 and i have lowered the back 25mm and the front 30mm and it fits fine. Im sure our civics can go 20" but try to get tyres which are 215 wide because mine are rubbing on the gaurds when the roads are uneven but it is still driveable. Remember the cost of tyres for 20" they are really expensive but if you got the cash go for it.

Here are some pics i have from the week end

it'll be a stiffer ride due to the thinner tyre walls...

the thing about big rims, u wanna babysit these wheels so that they remain in pristine condition...no more taking the speed humps at 15kmh's...

ur motor is more than adequate to haul these rims around...

is that the lowest u can go without having your tyres hitting the guards? when hitting bumps or going around round a bouts..??

hey frost, is that 225 thickness of tyre only rubbing cause u lowered ur car 30mm? I lowered mine about 15mm, and am wondering if I got 19s with 225s if they would rub like yours?

Also, can I see some more pics of ur car with the 19s? Just have a few questions:

How does the ride feel? how do you cope when you go into the country or gravel roads? How do you insure a car which illegally has 2 rim sizes too big? How often do you have to replace those 35 profile tyres?

I've been reading on 8thGenHondaCivic forums that people reckon an upgrade to 19s or 20s on this Honda would screwup various parts of the engine/rotors/manifold, anyone have any thoughts?

Well the rubbing on my car is bearable, just dont go around coners at high speeds and avoid uneven roads, this is where it rubs either then that its fine.

Yes it is illegal to go more the 2 sizes up but you can always say you had 17" on them but i dont think it really matters just aslong as your car isnt too low to the ground.

There is plenty of ground clearance putting 19" on my car and lowering it 30mm.

And for engine wise.. i think its fine you just pulling more weight so more petrol

i have 19s on my FD, and its fine.
in terms of fuel i get 500km a tank.
power- its fine for day to day drive.
handling- a little more shiff, but reduced understeer. turning circle is not that much affected.
no rubbing at all, becasue i rolled and flare the gruads out a bit.

i think ur overstateing some issues there. unless ur being a little bitch about every little thing on your car.

yeah more weight, and maybe low profile tyres im assuming .. may cause buckle in ur rims on some crappy roads

I have 97 Ek sedan with 19" .. no problem at all.. even with passangers at the back.
I have custom superlow King springs and Koni shock n rolled rear guards.
No problem with full turning circle..

I have to rolled the rear guards .. cuz the rim is 8" wide 19x8 .. bit fat.
Yes 35 series tyres ..

I like to ask you a few questions.

1. Do you like to waste your money?
2. Do you want people around you to think you're an uneducated unsophisticated fool?
3. Do you like suffering minor concussions while driving every day?

If you answer yes to at least 2/3 then I say get 20s for sure.

Does anyone know if 215/18/40 would be ok if my car came with 195/65/15? Would there be any probs with the brakes or any parts failing? How do people go with insurance companies if their rim size is 1 or 2 sizes too big?

mine 225/18/40. called NRMA, they said, ok. they only concern about the width size- maximum width they will accept is 9.5 (or 10 - i forgot ?).
but when i called RTA - 2 times,
once, they said, no probs, as long as overall diameter same like stock
but other, said, max go up 2 inch for size and width
:confused::confused:

SaBReT00tH
21-12-2007, 11:37 PM
what's NRMA and RTA?
Damn, I really want 19s, or at least 18s. Only things stopping me are making sure my car is insurance compliant, and making sure my ABS brakes don't ****up by increasing rim size too much.

21-12-2007, 11:40 PM
Frost FD --> did your Civic originally come with 15 inch rims when u upgraded to 19s? have u had any braking problems at all? what do u do with ur insurance if they're illegally too big?

TEGZOTIC

just remember that the 2" max law is an overall diamiter of the wheel not just the rim it self..

so if u can get extreemly low profile tyres on the 20's it might be with in the 2" range,,, but i doubt it

SaBReT00tH

Hey Teg, definitely don't think I'm going to get 20s. I'm kind of feeling deterred enough from the performance reviews of Frosts 19s.

With maintaining the same diameter I believe it's possible by going down to 30 size profile tyres. I'm still contemplating a tossup between 18s and 19s in which I would want to get 35 profile tyres, purely for the look. If I got 18s I'd need to get 235 thickness tyres for 35 profile, and I"m just wondering what the difference is between this and the 8" size of the tyre. For example would a 215 appear like there is less tyre there than a 235? And is 235 going to have less handling/sidewall than a 215?

I'm thinking that if I got a 235/35/18 and then got the Mugen kit installed it'd look a hell of a lot normal than the current 215/45/17 that my car is dwarfed by at the moment. Although comfort would have decreased slightly due to the 35 size tyre, i'd still maintain fuel consumption better than heavy 19s/20s, probably not have any additional significant braking problems as I would with 19s/20s, nor would I lose much horsepower cause i'd have 18s compared to pushing 19/20 inch rims around. I believe the sports exhaust system I got installed a few months ago will help maintain the horsepower input for pushing the 18s and am possibly thinking about an Injen CAI which would also help with them.

I do think 20 inch rims with 30 profile tyre does look over the top, and even 19s can look a bit over the top by appearing over-proportional to the car itself. 18s look ultimate, preferably with 35 profile tyre in my opinion and carefully chosen rim design. The 235 width tyres I've been looking at do seem to give the rims an awesome chunky wide fat tyre look with low profile and would hopefully wear out less quickly than say a 215 width tyre.

well 15" rims with 65mm tyres is about 20" overall. so you'd need 25mm profile tyres to be safe... do they even make these? you wouldn't want to hit any bumps/potholes!!

Hey Sabretooth, If you going for racing get 18 or 17"

Since your getting a mugen kit or have one install go the racing look!

hey Frost,
so you don't think 45 profile tyres look miniature on a standard FD, or especially on an FD with Mugen kit?

I was thinking about doing that 'racing' kinda look, even though my wheels are chrome (pimp) style rather than racing style. Leaving my rims as they are now would help me stay legal, and fix insurance legalities/maintain performance/save petrol too. Maybe I should just concentrate on 6000K HID projector retrofitting/Body Kit installation and possible CAI installation so my car can stop getting left behind at the lights with the masses of Holden Commodores passing me embaressingly in my city!!!

Frost_FD
27-12-2007, 09:58 AM
I dont think we can fit 45 profile tyres on our cars with 18" or 19" mine are 35 and i get abit of rub so 45 will rub big time and then you will have to roll your gaurds which cost another 300 bucks...

Im going for the HID and body next when i have abit of money spare

SaBReT00tH

sorry, I meant 45s on my existing 17s. If I upgraded to 18s I'd need 40s and 19s would need 35s, preferably with 215width tyres to prevent guard rub.

I've changed my mind again, I want 19s without a doubt, to complete the overall look and reduce dwarsim of rim to body ratio which would be worse if I installed a Mugen replica kit.

My plan is CAI first then 19 inch wheel upgrade. I want to avoid that complete $300 wastage of guard rolling by using 215 width tyres.

My only concern now is the question of braking.

Will upgrading 4 rim sizes past OEM screw ABS braking up? Would I need to upgrade the braking kit and how much will it cost?

By the way, has anyone heard much about nitrogen inflation of tyres? A guy in a tyre store told me this is one way to counteract the harshness of lower profile tyres.

Frost_FD
03-01-2008, 09:58 AM
My wheels are 225/35/19 and i lowered it at the front 3cm and at the back 2.5 using king springs. I havent rolled my gaurds yet but i did get some rub when i went over uneven roads but now that the springs have settled in it rarely rubs unless your going really fast around coners and bumps.

Braking wise... i am thinking about getting better brakes but i think our stock ones are fine for now especilly when my types and wheels weigh more then 100 kg.

I will read up the nitrogen inflation that might help the ride confort.

i've heard about nitrogen inflation but seeing that air is already 78% nitrogen (http://en.wikipedia.org/wiki/Air) I really cant see there being too much benefit

hey guys

im after a set of buddyclub 17" P1 SF

Dont know which offsets and size will fit on the FD1

Would the whole range fit without any problems?

How do I find out?

js0n1
05-01-2008, 10:40 AM
go down to a rim shop tell them what car you got, and they'll probably take out a bunch of catalogues and point out what will fit on the fd1

then compare the size and offsets with the buddyclub range to get a rough idea

SaBReT00tH
09-01-2008, 10:30 AM
hey guys,
just wondering if ABS brakes would be affect to a dangerous degree, going from stock 15s to 19 inch chromes? Would an expensive $1,000 brake upgrade be mandatory for safety?

Also, would there be any issues with unsprung weight if I'd already substitute my springs by putting in Kings sprinsg and lowering the car half an inch?

correct me if im wrong but the stock alloys on VTI models are 15", correct?

so would i be able to fit 16" or 17" intergra-R rims onto the wheels without changing tires and having any problems???
