I've an unused front pair of AD08RS
205/45/R16
Just not got round to fitting them

Thanks for the offer.
Rears are 235/45 17. I have to have a front tyre that will fit within the 5% 4 channel ABS margin. So 205/55 is 1.6% difference and 205/50 4.7% which is probably too close allowing for wear. Also there is the Racelogic Traction control tolerance to consider (which I can't remember off the top of my head.

Retrospectively 235/40 17 - 205/5016 might have been a better choise. Not sure why I went for the former, perhaps the traction control differential was a factor

205/55 is the sort of tyre you'd fit on a bog standard VW golf made for comfort. A very bizarre choice for a VX220

225/45x17 vs 205/50x16 is a 3.75% difference
235/45x17 vs 205/50x16 is a 5.22% difference
235/40x17 vs 205/50x16 is a 1.37% difference

Even 205/50 do look a little boaty, but seem to work ok. Surprising what was once considered low profile, I'm saying looks boaty !! lol

You're right of course, but if my recollection is correct, one of the primary objectives in choosing this size was that I would not have to re-calibrate my traction control. It's so long since I did that I can't even remember precisely how it was done other than going to a very large public car park somewhere and driving around experimentally to get it to work with 17" standard wheels. So basically a lazy choice because I have a 16/17 combination with no advantage from the 16" rims.

If it's the race logic tcs it's easy to re configure for tyre sizes as I've previously said on this thread

IF, you have a laptop, which I don't. but problem solved now anyway.

A desktop pc will work just as well

I have a brand new set of front and a good set of rear AO52s. Rears you can probably have for nothing, fronts though owe me £550.

Thank you for your kind offer, but I have managed to sort the problem.
