Got the 18's on to replace the 17's yesterday. Had a drive down the motorway to Manchester and back today and the car feels a little different now.
Ride - slightly harder and not as comfy (slightly) to be expected.
Road noise - A little more, again with wider, lower profile rubber, to be expected.
Handling - Feels more planted and little more direct, good thing.
Performance - The 18' are heavier than the 17's and i felt there was a little edge taken off acceleration. Only noticed this at lower speeds and it was only slight.
Overall I like the more secure feel and sharpness to the steering. I can handle the slightly less comfortable ride and increased road noise and this might be improved with different tyres wwhen it's time to change (bridgestones, same as were on my 17's). Plus it looks so much better.
Anyone else had a similar experience?
