Can i just ask, Does it make a difference if you have bigger wheels and if so why ?I have a swb 150 dsg and have towed our 1800kg twin axle caravan for the last 2.5 years with no problems even with 20's.
Sometimes need to drop into sport on long hills
Thanks for that tip. I don't tow often but its sometimes heavy plant and thats worth considering.Reversing with a loaded trailer can over heat the DSG and go into shut down until it has cooled.
Happened to me once trying to reverse trailer up a slight gradient.

I rarely tow and my wheels are 17 inch but every day is a school day and thank you @Dieseldonkey for taking the time to explain that to me.Its not so much the 20 inch wheel @Lord Mfwic that changes things. But the combination of a wheel with a larger radius and fitted with a tyre that doesn't have a low enough profile to compensate in maintaining the standard tyre circumference. This will create a combined drive train with taller/higher/longer gearing. Not as extreme perhaps, but along the same lines as trying to pull away from a standing start in 2nd, instead of 1st. Big diameter tyres = less torque = less acceleration.
Then there's the difference in aerodynamic drag, when at speed especially, if the tyres fitted on 20's are wider. Also different (usually but not always necessarily greater) rolling resistance.
I'm sure @Loz will be along in a minute to tell you what other efficiency it also effects.....
I do find that when I run on the 16 inch winters I can get a bit more wheel spin when setting off over the 20's but I put that down to less contact patch of the tyres. 215 vs 275I rarely tow and my wheels are 17 inch but every day is a school day and thank you @Dieseldonkey for taking the time to explain that to me.
I tow a 2 tonne boat with a LWB 204 DSG 4mot. Tows like a dream.Thinking about a change of van , always had manuals till now .
How does the dsg perform for towing ( big caravan ) ??
