Hi Guys,


after six years with the continental as per dimensions below

225/40 ZR18 9Y EXTRA LOAD ,, FRONT

245/35 ZR18 9Y EXTRA LOAD ,, BACK

it's time of renewal, then I've checked the below

DUNLOP SPORT MAXX RT
GOOD YEAR F1 ASYMETRIC 2
CONTINENTAL SPORT 5
HANKOOK


the use that I do is mainly in the city of Athens, with some trips to national and little mountain rides for a little fun,

like to have a very contractual driving without strong overtaking and passion!

I need your experience and feedback of what to put, since the prices are almost the same,

I have the sport package ordered and installed to my car from the beginning upon car initial order , with 18" alloy light wheels , can I reduce the dimm of my tyres front and back but keeping the 18" alloy wheels ?

Yes you can, but within limits ofcourse. Much depends on the widht of your rims.
Take a look here Tyre equivalence: Car tyre tips - Pneus Online


About your tyres, I have only experience with Continental and Michelin. Personally I prefer the Michelin Pilot Sport 3. But I think if you don't push your car to the limits any premium brand will do. Don't know about Hankook, here it is not considered premium, which does not mean it is bad ofcourse.

I have the Hankook, fair, but definitely not the same in terms of traction as compared to Contenental.

Sorry guys now it hit me,,, in my datacard provided from here with many tanks I re confirm that I had 18" alloy light wheels and sport packet , but can I find which was the dim of my tires upon order.

I bought my car second hand so I found with the above dim , please can you assist ?

Moreover I have decided if it is ok to go with Goodyear 225/40 w92 xl r18 instead of zr and for back 245/40 w92 xl r18 instead of 245/35 zr92 xl r18 which is fitted now

Again, that depends on the size of your rims. If you car came width 18" rims and you have now 225 front and 245 rear, than it would be safe bet to assume you have now a rimwidth of 7.5 front and 8.5 rear. The setup you have now would then be the recommended setup by MB and most likely your car was delivered with this setup. See attachment.

Many thanks

Finally I have decided to downgrade to the following

I will buy for front 225/40 r18 92y w instead of 225/40 r18 zr which are what I have now

I will buy for back 245/40 r18 97y w instead of 245/35 r18 zr which what I have now.

Brand goodyear
type efficient grip performance summer tires with B in fuel saving and A in wet road with 69 decibel

Need your opinions on this ,

Apart from the brand (which is fine I guess) I would stick to 245/35 for size for your rear tyres.
If you chose 245/40 the diameter of your rear wheel will be about 2.5 % larger than your front wheel. With 245/35 the difference will be -1,25 %. This is a sigificant difference from the MB recommandation. Don't know if your ESP is gonna like this. You might get all kind of error messages. Or maybe not but it is an expensive way to find out. I would stick to 245/35 or 255/35.

I have no real recommendation. The Goodyear's you chose will be fine. I myself have Michelin's but mainly because they were fitted when I bought the car an I was satisfied with them. So I stuck with them. Like I said, since you don't push your car to the limits, and neither do I for that matter, I think any premium brand will do.
Goodyear is fine.
