Thanks all.
You're right, the 20's are silly expensive but they do look good and the car doesn't do much mileage so we should get a few years out of a set. It's just painful when they do need changing. At least it only needs 2 at this stage.
I'll take your advice and get some Pirellis.

To be honest I am tempted by some more 'mid range' tyres. I had this quandry on my Merc a few years back. Had to replace the continentals it came with but didn't have the budget for top end tyres and i was doing a lot of mileage so bought some Avons at 2/3rds of the price, figuring they'd probably slide off the road but as they'd also only last a few weeks, I'd live with it and at least I'd know for sure and it'd buy me some time before I needed to swap them out for Contis again.
Turned out, they were the equal to the Contis in every sense (aside from price) and I never put a premium tyre on that car from that day on. Had Federal (grippy but noisy), Khumo (my favourite) and all were excellent and lasted just as long as the contis.
Only the DS is the wife's car and at the moment I'm fighting a drumming vibration at speed on it (wheels have been balanced, 4 wheel alignment done and if anything it's now worse than ever) and I know there can be balancing issues with cheaper tyres so I want to get the very best quality I can. Plus as I say, she's not doing many miles and with my Jag being near 300bhp and capable of spinning up pretty much any tyre in the wet, I only put premium on that so it'd feel wrong putting budgets on the wife's whilst buying premium for myself.
So I'm going to swap out the fronts (down to 2mm) with new Pirellis, put them on the back, and rotate the current rear contis (4-5mm) to the front. Then see how it drives and go from there.
