Hi all,

This is my first post here so be nice ;)

I have recently become the new owner of a Kia Ceed (mk2 - 62 plate) 1.6 CRDi and I was considering buying the following alloys and would like some advice:

Kia Soul 18" Alloy Wheel - 10 Spoke

Firstly, I know these are list as Kia Soul alloys but I assume that they will fit my vehicle? Also, these alloys are rather large (18 inch) will this cause any issues at all?

Thanks :D

We run Soul 16" alloys on our Ceed with winter tyres on. They are exactly the same fitting dimensions as the Ceed alloys.

But as for the 18" wheel it was never offered by Kia as a factory option on the Ceed (as far as I am aware) thus you would need to check body clearances carefully.

One thing they will do for your Ceed is make the ride very hard, possibly intolerably so. They are also very heavy and will put additional strain on suspension components on the long term. This may affect the warranty on suspension components but you would only find out if you had a claim.

There's a measurement called the "Off-Set" which determines whether the wheel will be suitable. It's the distance between mounting surface and inner side of rim, (but there is an alternative method of expressing this). Since the 18" wheel is probably wider, you may have a problem, but the easiest way is to check clearance. Check front and back.

The overall diameter of the wheel+tyre should be about the same as your existing 15" or 16" setup. This means that you have less rubber between the rim and the road, hence the comment about the ride. Personally, I wouldn't do it; our Cerato is fine on 15" steel, and the tyres are a much better price. Higher profile tyres are more resistant to "kerb rash" and other obstacles.

Ah - these were the kind of things I was worried about...

My original plan was to find some 17" alloys to match the top of the range model but when I came across these, well, I fell in love just a little bit :) but I suppose with so many potential issues and other such things to consider, it might be best to go back to square one and hunt down some 17 inchers...

Thanks for the info guys - and if you have any recommendations of where to look for some genuine Kia wheels, that would be greatly appreciated.

Cheers ;)

Ok... let me try to clear some information here.
Tire size: Ceed runs 225/45R17, of you go for 18" you must go for 225/40R18

Offset: The original 17" are 17x7j ET56 (Diameter, width, offset). The rims on the link are the same width, and have no information on Offset. But 56 is so high, that you will probable have no issues. You can go as low as 38-40 on a 7j rim.
The main issue with 18" is the weight. you will notice a bit of performance drop if they are heavier.

I run mine with a set of Team Dynamics Pro Race 1.2 18x8ET28 (very light and stiff), I have a bit of rubbing, but great looks! :)
Still on an 18x8, you can have ET35 with no problems, and maintain a nice looking wheel.

To me these are the best wheels you can get, because of their durability and extreme low weight.

Strictly a matter of opinion, but I think that 18" wheels are out of place on a fairly standard car. I'm also not convinced by the weight considerations and the supposed influence on performance. Just how much difference in weight is there between 17" and 18" when you include the tyre?

Maybe I'm a bit "old school", but for many years, the standard fitment on medium-large family cars was a 15" steel wheel. I once changed over to 16" alloys (mainly for cosmetic reasons) and found no difference in performance apart from some improvement due to the extra tyre width.

Partly, the desire for alloys stems from the ugly design of the plastic wheel trims that come with steel wheels. Replacement OEM trims are a bit pricey as well, especially the ones that are designed to fall off; canny owners use cable-ties to keep them on... Cool!

Luckily, the Cerato trims aren't offensive, and they are bolted on. Pity the garage guy forgets to correctly orient the valve-stem cut-out if he removes a wheel.

Wry 'Cuda,
There is a BIG difference if you run a heavier wheel than a lighter one.
I've had 2 sets of 18", the current one: 8Kg each and a set of Mille Miglia HT3 (12kg).
The standard 17" Ceed rim weighs 11Kg and they behave the same as the lighter 18". The Mille Miglias had worse acceleration and a lot worse braking performance.
The reason is unsprung weight.

I also have a set of 17" OZ Superleggera (~6.8Kg) for trackday use and the acceleration and braking is completely different for the better.

yes, I'm aware of that, but a few kilos isn't going to make a difference to anything for ordinary cars on public roads. Maybe 1% change in overall mass and 10% change in unsprung mass and angular acceleration of the wheels. You might feel it on the track, but most of what you feel will be due to tyre characteristics.

I've seen cars where the wheels and tyres are worth more than the rest of the car. Often, the brake rotors cower pathetically inside 18" or 19" alloys, and the whole effect is silly. In addition, the matching low-profile tyres are totally unsuitable, and give little protection from normal road hazards. It is sometimes forgotten that tyre profile includes that part of the tyre which extends down to the bead seat and which is not visible behind the outer rim. That's why low profile tyres have an exaggerated profile appearance.

Hey everyone,

Sorry to steal the thread, but I might as well not start another one if someone can give me a piece of advice. I'm looking for some 16 inch alloys to go with some snow tyres on my 2012 Cee'd and this is the situation:

I have stock all-season tyres (205/55R16) and stock alloys 6,5Jx16 / ET51.
My winter winter tyres are the sale (205/55R16). I'm looking for 16 inchers which would be interchangeable with the stock ones on both my sets of tyres, but since this is the first time I'm buying I'm not sure if they'll fit. I'm currently looking at these which seem to be 7Jx16 / ET42.

I'm mostly worried that the 42mm offset is much too different than the 51mm on the Kia alloys, and that they'll stick out too much. However, I'm can't seem to find a lot of alloys that have such a high offset. Do you think these ones will fit my car without causing problems to the suspension/rubbing against the bodywork ?
