I was under the impression that the i10 Style came with 15" alloys.
My i10 Style has Hankook tyres fitted that are 165/60/R14.
Is this right for the Style model?
The reason I am querying this is because a 1" difference in rim and tyre size is going to make a difference in the MPG figures!
Anyone any info on this? :liebe011:

on monday i will be completing the change to 165/65 which are significantly cheaper than the 165/60 fitment. i can finally get back to being fully fitted with michelin tyres, the hankook's don't do enough miles for me and the miles i cover.

first pair changed at 20'000 miles and the second pair will be changed at about 30'000 miles. i'll be expecting 50% more miles from the michelin tyres.

As far as i can see every UK supplied i10 has 165/60/14 tyres as standard.

Using any other than standard will result in problems with ABS/EBD and ESP (if fitted). As for MPG worries GET OVER IT!!

looking at the sticker in the driver door way

tyres shall have a load rating of at least 75 and a speed rating of at least T

the michelin are speed rated T and load rated 79, so having a better rating than the hankook tyres

and as for shouting over an issue not raised in this thread ???

forgot to say that before deciding to change the tyre size i had consulted my hyundai dealer and the tyre fitters, both stated that there would be minimal effects from this change.

I am absolutely sure you are right Mike.
I fully intend to follow your lead and fit the cheaper tyres as you have when mine wear out.

Well it would take more to convince me than a secondhand word off the internet on a subject as important as tyres and safety.

I'm no mechanic but common sense and school maths says that there will be changes in the cars suspension and steering geometry from which it was tested and designed.

For a start, the change in rolling radius will effectively gear the car up resulting in slower acceleration - that will also under-read the speedo.

It will change the ride height resulting in changing the centre of gravity and characteristics of air-bag deployment points and pedestrian safety.

The handbooks says:

"The tyres (specification) supplied on your new vehicle are chosen to provide the best performance for normal driving" 8:2

"...using tyres and wheels other than the recommended sizes could cause unusual handling characteristics and poor vehicle control, resulting in a serious accident." 7:34

So why didn't Hyundia develop and specify 65 profiles from new if there would be "minimal changes"? They'd of saved a fortune right?

So if i were to (which I won't) change from the specified tyres, I'd want acknowledgement "in writing" from Hyundia UK and my insurance company.

This is my opinion and of course you are welcome to yours.

there are several different tyre sizes fitted to the i10, 165/60 and 175/60 and the indian market gets 155/80R13

comparing 175/60 = 105mm to 165/65 = 107.25mm, only a 2.5mm difference

at 70mph speedo = 65mph sat-nav, changing give an increase of 2mph at 70mph. So now at speedo 70mph sat-nav should read 67mph

165/60/14 to 165/65/14 is a 2.89% difference. 2.5% is the acceptable Maximum.
all of the sources i have discovered have recommended a change of less than 3%

as for choice of hankook and the 165/60 tyre ?

maybe its to sell more hankook tyres, as we get very little choice of tyres at this size ?

a south korean car company supporting a south korean tye company ?

Learn with Mike,

I will be interested in how European tyres effect the ride and noise transmission.
After all I imagine the Original Equipment must have been very cheap.

How about tyre pressures? Far as I can see Hyundai recommend the same no matter what tyre is fitted!!

Could you perhaps get away with slightly less pressure as cross section is larger or more pressure to maintain the same foorprint?

"comparing 175/60 = 105mm to 165/65 = 107.25mm, only a 2.5mm difference"

I assume 105 and 107.25 in the height of the side wall.

If these are added (X2) to the wheel diameter of 14inch (35.56 cms)

These would give total diameters of 3766 and 3770 mm respectively .

Times pye = 11836 and 11849 mm circumference.

An increase of 0.11%! Which doesn't seem right!

I'm not sure where you got the 105mm from as 60% of 165 is 99mm.
which give 3754 / 11798. Difference = 51mm or about 5%.

Or have I got this entirely wrong?

the market for tyres in the size 165/60R14T seems to be improving, blackcircles.com now have 14 tyres options for our size

they are still more expensive than the 165/65 but we can now have a choice of what tyre we fit
