My 225/55 R16 summer tyres will soon need to be replaced and when getting new ones,
I'm considering to go down in widh. 205/60 R16 has almost the same circumference, would it be
a good idea to choose this size considering handling, stability, noise level, fuel consumtion, etc.?
-
Generally speaking, stick with the manufacturer's spec, it's what the car is built around :y

Logical, but 195/65 R15, which is more narrow and higher in profile, is also according to manufacturer's spec.
My thought was that 205/60 R16 would be a good compromise :-\

Is there anyone here that uses 205/60 R16 on the Omega?
-
No, sorry I haven't but I shall be following this with interest as I was thinking exactly the same myself.

Sounds perfectly sensible to me.Imo the wider tyres are more for cosmetic reasons than anything else. Im not an expert however,so wait for other opinions.
-
Are you thinking 205/60 purely due to cost of tyre?

Main reasons would be lower noise level, better grip on wet/rainy roads, lower fuel consumption, less risk of tramlining, etc.
If the tyre itself is cheaper, that isn't a disadvantage :y
-
I have tried 195/60-15,205/55-16,215/55-16 and finally 225/45-17
from those 215/55-16 was ideal in terms of comfort , fuel economy, tramlining and grip but that was with a potenza tire..so a different tire with same size may show different behavior.. 225/45-17 is better in grip and fast curves , but not sure for fuel economy :-\
and prices different of course..
ps: also checked the speedo with GPS and odometer maximum difference was 3-4kms per/100 km..

Originally facelifts have been made with 205/65/15 tyres in basic specs. Pre-facelifts (some of them) came with 195/65/15 tyres which IMHO are a bit under-sized to an Omega and might not have adequate load rate (94 is minimum IIRC)
So, for facelifts the "factory sizes" were:
205/65/15
225/55/16
235/45/17
And that's it. As said, some early cars came with 195/65/15 tyres.
As these are the factory options they must have had something to base ther decisions on so I would start from these and if for some odd reason you would want any other size, use one of the size-calculators to find the next-closest option.
-
The question will be if your rim width is compatible with the narrower tyres. Check the manufacturer's specs for the tyre.
Of course, it could be classed as a modification, which will bring insurance hassles. Might be easier all round to stick with standard.
-
Get the standard size? They're that size for a reason :y.

size 205/65-15 225/55-16 235/45-17
diameter 647.5 mm 653.9 mm 643.3 mm
circumference 2034.2 mm 2054.3 mm 2021 mm
all different width, different height and wall thickness ..all for the same car.. I'm not that sure , factory knows the reason why they choose them ;D ;D
215 andd 225 sizes all can be used without problems.. and even 195.. I use it in winter months .. no probs so far..

Thanks for all your input :)
I have spent several hours the last days surfing the net :D and most likely I will stick to the standard size 225/55 16 (possibly 215).
In the winter, I use 195/65 15 tyres as well- Kumho KW22 (studded)- which works great, both on snow/ice and bare asphalt. :)
Now, does anyone know if Nexen N6000 works well on the Omega? This tyre seems to be a fair choice and offer good value and safety for the money.
One of the important things for me (besides that the tyres should keep me on the road of course ;)), is that tramlining doesn't appear.
Nexen is used as OEM tyes for some Korean cars, which should give some indication that the quality isn't the worst.
Sofar I havn't found any tests on N6000 carried out by motor magazines or similar, but user reviews in general are quite positive.
Not that many years ago, people were very skeptical (at least here in Sweden) to both Hankook and Kumho, which both are made in Korea as well.
Today the situation is totally different and both brands are considered to be good, or even very good, alternatives.
Perhaps we will se the same with Nexen in the future, when the brand is getting more well-known, who knows? ???
All Nexen N6000 experiences are greatly appriciated :y
-
you live in sweden .. its a cold climate.. and probably hot days are limited.. so I would definitely go for an all season tire even in summer.. kumho and hankook good in dry but not that successful in cold and wet .. and nexen not better than them.. :-\

Well, I don't live that far up, actually I am in the very south of Sweden. Think Denmark instead, thats how far north i am :)
(as a matter of fact, I do believe it rains more in England, ;))
Regarding the wet grip, check this test, Hankook Ventus Prime 2 got top results in the wet (and dry) and actually won the entire test :y

Last time I was in Sweden in summer it was 30C and brilliant sunshine the entire time.. (and that was Stockholm) gorgeous climate up there!

Hankook generally have good results.. But these are with fresh tires.. I have witnessed that they harden quicker than some expensive brands.. and also those varying test results about tires remind me an interesting point.. at what temperature they test the tires..most of those tests dont give any info about that :-\

It looks like the Nexen N8000 is the sweet spot for me, a Korean tyre (should not be referred to as a "cheap China tyre" ;)) at a very low price with good test results both in dry and wet road conditions. On the down side is fast wear and increased fuel consumption which is no problem for me since I only drive 3000-4000 miles a year (of which 2/3 on summer tires and 1/3 of winter tires). Will take a while to wear down the tyres with such a low mileage ... :)

obviously korean tires different than cheaper china brands..
ther reason I recommend all season tires was they will keep their softness when the temperatures starts to drop..
and I'm not sure those tests will keep their validity for a wide temperature range..
I have used korean tires in the past.. at that time , their compounds were designed for long life instead of short (Hankooks) but sacrificing grip in cold weathers ( it was 1-2 mm less than original thread depth after 5 years and 40K kms ??? - ps: I have 2 cars) .. now they may have changed the design.. but from experience I know good quality rubber is always expensive which may hardly change.. there are tricks for factories to cheat in tests, but no one can cheat in cold weather ;D be it in autumn or winter or any other time..

You have a point there but as I donīt intend to use these tyres during the winter, they will rarely be exposed to particularly low temperatures.
In Sweden it is aloud to use winter tyres between October 1st and April 15th (mandatory between December 1st and March 31st) which gives you plenty of room to put on the "winter boots" in appropriate time.(A general recommendation is to put on the winter tyres when the temperature is getting below +5C.)
