I agree with your comments completely but I'd rather have a car that steers accurately in the direction that the driver is anticipating it going in, especially on the m/way at 70+ mph and maybe lose some ride quality in the process. I don't find the ride at those pressures unduly hard but I guess we all perceive these inputs differently, Not that I'm condoning the reality of this situation as there is no doubt in my mind there is a fundamental issue with the vehicle in this context.
Also, bearing in mind the number of owners contributing to this thread who are having issues when towing clearly validates this as a LR problem!
Hi all just been reading some of the pages on this thread. I have a D5 since 19.07 so haven’t got around to putting the T/A on the back yet. I had it on the D4 before the crankshaft snapped and it towed perfectly no bounce or wobble at all. Not sure if I have the tow assist or anything on the thing. My question is has any one come to a conclusion as to possible cause. The D4 I towed with tyre pressures at normal and high with not much difference. Any thoughts or anything greatly received.
I am still trying to figure this thing out. As a side thought can I find out somehow what is fitted to it
reading this lengthy and very interesting thread I get the impression the placing of bikes on the A frame (or the tail of the tin tent) is the potential cause of a wobble
Hi All, it's taken a long time for me to get back to this thread so apologies for that, my excuse is that I don't do that many miles so have been cautious about making an update before being certain I have cured the problem on my car.
So, when I bought the car it had cheapo tyres on the front and Pirelli Verdes (LR) on the back. My 1st trip back home from the garage I bought the car from gave me cause for concern as it was moving about on the M/way in the middle lane at 70mph, which I would loosely describe as tramlining (see previous posts), although there didn't appear to be any issue with the road surface that could have caused this. I was also occasionally getting the "Traction Reduced" message on the dash on a dry road. I subsequently identified that the cheapo front tyres had a rolling radius of anything between 1.0 and 1.5 cm (depending on static pressures) less than the rears which I believe was setting up a transmission wind-up situation as the wheel revs / mile were at least 2% more on the fronts thus causing the vehicle to detect wheel skip and so causing the movement of the car for no apparent reason. This was confirmed as the message never appeared when driving on wet / damp road surfaces as the wheels could slip to eliminate the wind-up. I have now fitted the same new front tyres (Pirelli Verde (LR)) and driven quite a number of miles and the car now tracks absolutely straight and true with no tramlining and no message on the dash. So, clearly a tyre make problem exacerbated by incorrect pressure settings which is now resolved using the correct LR tyres and pressures on all four corners. I hope this might throw some light on the issues people are having when towing although I do appreciate that when towing there are a lot of other inputs for getting the best set-up that also need to be considered to achieve a stable situation.
Pressures with the Verdes are 35/36 psi front and 38/39 psi rear. I'm generally running 2 psi above the LR values as I do carry a bit of load which is in between the "light load & heavy load" settings.
Front tyres were Minnell Safy M06. I've never bought budget tyres ever and this experience has re-inforced that approach to be the right one - see photo.
