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

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?

[bootie]

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.

[sticka_v8_init]

Are you thinking 205/60 purely due to cost of tyre?

[Thingymabob]

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

[cem_devecioglu]

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.

[Del Boy]

Get the standard size? They're that size for a reason  .

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  
 
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 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

[cem_devecioglu]

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..
