Landsail isn't a make many of us here would recommend and if you said it felt like four wheel steering in the wet no one would have been in the least surprised.

However it does seem odd that you find such a ride difference on a softly sprung car like a Xsara (VTR/S excluded)...unless the tyre load index is commercial van spec, could be partly that but Berlingos with the same suspension as your Xsara are wonderfully soft riding on van tyres.

As Skidpan mentions, check the tyres are at recommended normal load/speed pressure (lower of the probably two recommended pressures) and see how they are after a few miles to bed in.

The garage that fitted them let some air out to try to soften them but they're still the same very hard ride. They've checked the BACK suspension because they don't think it's the tyres. I drive across 5 calmers across the road where I live almost every day the bump was quite soft.Since these tyres where fitted it is very hard on BOTH front and rear wheels. I mean no disrespect to the mechanics but I would think it seems quite obvious that it's the tyres. The ride was smooth until these LANDSAIL LS 288 were fitted. Am I making sense please.
