I have a 2015 Tekna with 19" alloys and am finding the ride is rough on bumpy roads compared to other cars with higher profile tyres. Hence I am thinking of changing the wheels to 17", but this will set me back £1400 in total. Is anyone interested in buying the 19" alloys and / or tyres? Three are in factory condition, one has a minor scratch. Pickup can be from either Hampshire or Dorset. Price is negotiable. I will consider a no-cost part exchange for 17" alloys/wheels.

The circumference of the type will slightly increase with the added fact that your speedo will have increased accuracy as most speedo's over read by 3 - 4 mph. I went from 205/40 17 on the mini cooper s to 205/45 17 and the speedo was nearly spot on to GPS speed and had increased noise reduction and comfort

The only way I can legally increase the aspect ratio is by reducing the R diameter to accommodate a higher sidewall, and thereby maintain the same overall (outer diameter).
Hence my plan to swap my 19" alloys to Tekna factory 17" ones. Anyone has experience of doing this on the Qashqai: does it soften the ride?
I am also looking to sell or swap my 19" alloys, if there are any takers out there.

I have to say I'd be extremely cautions with taking this approach as the legality and safety of such a change may be questionable! A change from a 40 to 45 aspect equates to a 10% speedo error.
The only viable way to change aspect ratios is to also reduce the tyre width, so going to a 205x50 should work but its unlikely to give any improved comfort as the side wall's virtually the same depth.
Perhaps a cushion would be a cheaper alternative?
