Hello all,

 

My superb mk2 elegance is running the oem 18inch elegance alloys with 225/40/18 tyres but feels very stiff on the road, has anyone else similar issues? What psi are other running with this tyre size? 

 

Thanks

There are many threads about the hard ride that you get if you use 225/40R18 tyres on the Superb MK2.

 

I can see the appeal of this tyre size for an Octavia VRS owner, but on the Superb MK2 205/55R16 or 225/45R17 makes a lot more sense.

 

To make a 205/55R16 ride as hard as a 225/40R18, you would probably have to over-inflate the 205/55R16 by about 10psi. Considering that it's easy to notice a 3psi difference in tyre pressure, a 10psi difference is massive. Hence changing from a 225/40R18 to a 205/55R16 will transform the ride. However, if changing to the 205/55R16 size on the Superb MK2, I would suggest using 6Jx16 ET43 rims (from the Karoq) rather than the standard 7Jx16 ET45 rims. This is because 205/55R16 fitted to a narrower 6J rim rides noticeably softer than when fitted to a wider 7J rim.

 

As well as the standard 7Jx16 ET45 rim, the Superb MK2 does have a 6Jx16 ET50 winter rim option that's suitable for use with snowchains. However, if you're not going to use snowchains, 6Jx16 ET43 rims (from the Karoq) might be a better option, as 205/55R16 fitted to a 6Jx16 ET50 rim is a little sunken in the wheelarch and reduces the front and rear tracks by 10mm compared to using the standard ET45 rims.
