Hi, wondering if 18X9.5" wheels will fit on a ralliart with 225/40/18?

Cheers

that width is way too wide for 225 wide tyres. Max wheel width for 225/40R18 would be 8.5". With 9.5" wide wheel you need 245 wide tyres.

235-45 will fit at a stretch

so im guessing it wont fit without clearance issues?

Its not about clearances. 225 wide tyres cannot physically fit onto 9.5" wide tyres. My 225/45R18 tyres stretch to fit onto 18x8" wide wheels. 9.5" equals 241.3mm which is 16.3 mm wider than the tread surface of a 225 wide tyre and note that the bit of the tyres that fit onto the wheels are actually narrow than the tread surface.

ok. Just spoke to the guy selling them.. he said 2 wheels are 8.5" and 2 are 9.5".. i just want to know if the wheels will fit or if they are to wide.

cheers

Well it all depends on the offset of the rims, without that information then its almost impossible to say

My cousin has 18x9 +25 rear and +35 front offset on his ralliart, the front sits flush with the guard and the rears are slightly in the guards still with plenty of clearance for struts and other suspension arms

8.5" on the front and 9.5" on the back is a do-er - a couple of people have done it (Ralliart-AKKO and Cummins come to mind), although it does come down to offset.

And 225s are way too small for a 9.5" rim, even 245s (like TZABOY has) look VERY stretched on the rim.

here is the add if it helps..

Those tyres were most likely not off those wheels. There also may be legal issues with running differing width wheels and different offsets. Bear in mind offsets cannot be changed by more than 12.5mm because the track cannot be changed by more than 25mm. As I've said before and Red Valdez, 225 aint gonna fit onto a 9.5" wide tyre. Even 8.5 is stretching it. I know because I have 225 on 8 and it is a stretched fit.

hmm ok. Guess i will just have to try them out. The guy that is selling them works owns the Dunlop dealer so i think he would know his stuff

So what. I had a Bridgestone Tyre Centre spend 3 hours doing a balance and rotate on my previous KS Verada. Its simple mathematics. Have a play with this site (http://www.rimsntires.com/rt_specs.jsp) yourself and see if you can enter a 225/40 tyre on an 18" diamater wheel with width of 9.5. Goodluck.

well if it doesn't fit then it must be a different tyre on the 9.5" ones.

it IS possible, but for street i wouldnt recommend it

as seen you will get rim poke... while i love the stretched look.. very jdm lol id rather have the rim level with the lip of the tyre also its very hard to first seal the tyre with rim poke lol 235-245 would be more ideal and still give you stretch

^ i love that look!

That is so dangerous and irresponsible. I wouldn't want to hit a pot hole or kerb or go around a corner too fast.

is it? how?

Probably the dumbest thing i've seen on AMC!

Doesnt look bad in some of these rides.

8.5" on the front and 9.5" on the back is a do-er - a couple of people have done it (Ralliart-AKKO and Cummins come to mind), although it does come down to offset.

And 225s are way too small for a 9.5" rim, even 245s (like TZABOY has) look VERY stretched on the rim.

TZABOY has 235-45s dude

is it? how?

Think about it mate, if you stretch something, you leave weak spots with in a structure causing sag when moved this time around it’s your rubber.

I like the stretched look, but it does compromise the integrity of the rubber.

The photo above is just asking for trouble.

sorry some of us arent as educated as others in the wheel department BRO. Last time i checked i am pretty sure i posted a thread to get some advice to better educate myself..?

Righto, probably pass on it then. Cheers mate much appreciated

About that stretched look, the tyres are specifically designed to fit like that.
Personally I hate it with a passion.

FYI to the OP, any wheels wider than 8" are probably illegal, so you could be open for defects and personally I'd be worried about insurance claims if ever needed. (although I haven't personally heard of knocked back insurance claims because of 'illegal' modifications)

Streching thin tyres on wider wheels is one of the stupidest fads to ever come into the car scene.
It's downright dangerous. The reason it became popular is because of drifting in japan, where the young drifters with little money would buy big deep dish wheels for the look, but then end up not having enough money for the wider tyres. If they had 245s on it, they would stretch 225s and pump them up to around 42psi to avoid them coming off the bead, which is fine on the track but stupid on the road. Because people found it cool, it devloped into 40mm stretch, at which point any tyre manufactuer would call you a twit and any cop would smack you on the back of the head and call a tow truck.

If you came into the shop and asked us to fit 245s on a 9.5" wheel, we would refuse because we won't be held liable when the tyre comes off or shreds and you slide into a school bus. If you asked us to fit 225s on a 9.5" wheel, we would give you a blank look. You're asking to try and stretch 50mm and have the bead seal.


On the subject of wheels, it does depend on offset. Seeing as the wheels you are looking at are on ebay, with no details about them and no name of who made them, walk away.
9.5" are easily doable if you get the right offset, but for gods sake at least buy ones with a branding so you know you're not going to be braking hard when a spoke snaps or hit a pothole and have it buckle.


If you go for 18x9.5", look for 275/40R18 to keep rolling diameter. If they don't fit, 265/40R18 will throw it out only a little bit.

I haven't got any links handy, but it might be an idea for OP to check out some sites like Car Bibles, Autospeed etc to read-up on tyres/wheels and even suspension. Some tyre manufacturers sites may also have some info that would be instructive. Hell, even Wikipedia will have good info.

There's a lot of research and development goes into tyres and manufacturers probably desing in large safety margins. However, any tyre of a given width will be designed to suit a small range of rim widths that are reasonably close to the tyres nominal width - and that's the FIRST number given in the naming-scheme for tyre sizes.

Putting an over-wide tyre on a narrow rim, or (in your case) putting a narrow tyre onto a too-wide rim just places stresses on the tyre that it was NOT designed and manufactured to cope with. In both situations - rim too wide, or rim too narrow - the stresses are likely to be concentrated on the sidewalls of the tyre. Which is the thinnest and least reinforced section of just about any tyre - the SIDEWALL.

If you read-up on wheels as well as tyres, try to check-out the meaning of OFFSET. If a tyre is 8.5 or 9.5 inches wide, depending on how you manufacture your wheel there will be a wide range of possible offset - this refers to where across the width of the rim the flat surface than contacts your hubs sits. It "could" sit completely on the inner edge of the rim (in practice probably never does) so that the outer edge of your rim sat out 8.5 inches wider than the mating surface of your hubs. Likewise, if the flat of the rim was entirely on the outer edge (again, will never happen in the real world), then the inner edge of the rim would sit 8.5 inches inside the mating surface of the hubs. Offset is usually expressed in millimetres. Without knowing the offset of a certain set of rims, no-one can say with much idea whether they will clear the suspension and brakes on the inside of the rim, nor whether they will sit legally within the wheel-arch/guards on the outside of the rim. The size of rims and wheel-stud size/pattern and offset is usually cast into alloy rims (or stamped on steelies), often on the inside face where the numbers won't spoil the pretty design.

EDIT: Good ole Car-Bibles isn't too bad: http://www.carbibles.com/tyre_bible.html It doesn't mention Offset at all, sadly.
As a bonus, tho, it has a Blog in a side-box which bags Top Gear USA - gonna read that now for shits-n-giggles.

Completely wrong. The jap drift scene hasnt been around that long. Stretched tyres over wide rims has been the premise of euro tuners for far longer. VWs, opels and other euro hatches invented the stretched tyre look with 15x8 rims with 195 or 205 wide tyres

They might be genuine for that price, but they'll probably be buckled slightly and the finish won't be good.

They look more like Rota to me.

I meant the current styles we're getting, stretch over big JDM wheels. Hellaflush style has been around much longer but hasn't caught on in Australia yet, while JDM tyte has shown up here and NZ and taken Japan.

Euro stretch is different, small wheels with stupid amounts of lowering. They stretch for the reason of fitting the wheels under the gaurds.

I stand corrected, you know your shit :)

WHAT are you talking about, Willis ????

Let me enlighten the newby with a little quote from Wikipedia about drifting:

(Drifting) History

Japanese Origin
Modern drifting as a sport started out as a racing technique popular in the All Japan Touring Car Championship races over 30 years ago. Motorcycling legend turned driver, Kunimitsu Takahashi, was the foremost creator of drifting techniques in the 1970s. He is noted for hitting the apex (the point where the car is closest to the inside of a turn) at high speed and then drifting through the corner, preserving a high exit speed. This earned him several championships and a legion of fans who enjoyed the spectacle of smoking tires. The bias ply racing tires of the 1960s-1980s lent themselves to driving styles with a high slip angle. As professional racers in Japan drove this way, so did the street racers.
Keiichi Tsuchiya (known as the Dorikin/Drift King) became particularly interested by Takahashi's drift techniques. Tsuchiya began practicing his drifting skills on the mountain roads of Japan, and quickly gained a reputation amongst the racing crowd. In 1987, several popular car magazines and tuning garages agreed to produce a video of Tsuchiya's drifting skills. The video, known as Pluspy, became a hit and inspired many of the professional drifting drivers on the circuits today. In 1988, alongside Option magazine founder and chief editor Daijiro Inada, he would help to organize one of the first events specifically for drifting called the D1 Grand Prix. He also drifted every turn in Tsukuba Circuit in Japan.

So, "since the 1970's" isn't long enough for you? :)


As for Jap cars with stretched tyres - there was a fad years ago in Japan (probably still going strong) to modify cars in a "Bosozoku" (bike gang) style. That bike gang style is very old too.
Here's some examples at this webpage of the cars: http://www.examiner.com/autos-in-richmond/bosozoku-berserk-o

Ciao!

...Hellaflush style...


Mmmm hellaflush!!

Tried the rims on today.. they fitted well and looked good. Barely stuck out past the ralliart front and rear gaurds. Don't think i will buy them though.

By the way the brand is Sumbo or something rather

Found the exact wheels on the Zumbo site...

http://www.zumbowheels.com.au/Wheel_Range/m17_sectionid/2/m17_imageid/59/

oh and there all 8.5"

Nice post MattVR-X

The rim design looks nice, but yea, just make sure you don't cheap out on tyres mate. Good tyres are the most important safety device on any car!

I'm going to offer him $800, which he will probably say no but oh well i just wont buy them then

oh right, now wikipedia is gospel lol

How many westerners actually knew about the jap drift scene in the 70s? Not many I can tell you! Sure, it existed back then but who knew about it in other scenes around the world. Whereas the euro scene has been pushed in other car cultures for quite some time, particularly the UK, US, and russia.
