Kia Sorento KX2 auto 2016, caravan unsteady.

Thanks for all your useful replies, the good news is that I have solved the problem. It was all down to the cheap tyres that were fitted to the rear by the dealer when we purchased the car. We swapped the rear new tyres to the front and fitted the part worn Nexus tyres to the rear, job sorted as steady as a rock. So will wear out all four tyres and replace with good quality tyres proberbly Nexus or Kumho. Big thanks to all that took the time to respond.

i don't think it's advisable to fit new to front and put part worn on the rear.

Michelin et al do advise new tyres to the rear ...

Thanks MM for your confirmation. I thought it was new to rear.

just read your post!  We to are questioning is it the car or caravan!  Up until nov 17 we had a super cyclone elddis twin axle, the kia sorento pulled it with no issues, due to damp issues all the time we changed the van in nov 17 to the lunar delta r i, weve only used van 4 times since new due to family commintments this year, but on two occassions used motorway to get to sight, anf a fearful and dreaded journey for both times, swaying even at 49 mph.  A car sped by us and we were travelling at 53mph, we were swaying all over the place!!   30 years experience of towing single and twin axle vans, never before have we been so anxious on taking the van out, weve booked it in to get checked out but not till mid nov!!  Weve got a feeling they wil say nothing wrong! So weve then got to decide what we are going to do.  Could it be the car?

Maybe not but many of us do so.

I have the same problem with my 65 plate Sorento the caravan is all over the place i did have 2 mid range tyres put on the car after we bought it i wonder if its the tyres
