Tires MICHELIN or Continental

I have had Conti DW performance summer tires on my TDI for over a year, now, and run them between 40 - 41 psi. For me, that is a good compromise between handling and comfort, and gives the added benefits of longer tire life and better fuel economy. Note, however, that the standard sport suspension on the US TDI, while about equal in handling to the GTI on real roads, is a bit softer and more forgiving on bad roads. Also, 16" wheels help and are better suited to the chassis than 17" wheels.

Michelin Primacy MXM4 in 235/40/18 is exactly what I would do! I did similar with 17" wheels on my MKVI TDI and then my friend did it with the 18" wheels on his MKVI GTI. As for the Primacy MXM4, I love them. I've had mine for about 55K miles now and will be replacing them with the exact same thing when the time comes pretty soon, before the winter hits in Pennsylvania. But the tires really have lasted well and they are as quiet and comfortable as any tire I have ever had on a car.

four tires (Continental DW)

My Bridgestone's lasted about 38k miles. I thought the ride was bad. I put on Michelin Defenders at Sam's Club. I have about 77k on the Routan now; 39k miles on them. They are about half life. The ride is great. Very smooth compared to the Bridgestones.

I finally swapped in Pilot Sports. Much better riding car w/o the runflats.

I run a set of OZ Ultraleggera's which had Michelin PS2's , I just switched to RE-11's. Both of these tires are great, the RE-11 has a stiffer sidewall which effects a little grip but they hold there own for sure. The PS'2 had a better warning when at its limit and still had a little more.

Talk to Tire Rack and/or read all their test reports, and the only tire that is outstanding for your objective, and for DD road use, is the Michelin Pilot Super Sport, or the Bridgestone RE-11.

Try Michelin mxv4.

If its the tires its time to invest in some Continental DWS

I would recommend Michelin and BFGoodrich. I've had good experiences at Americas Tire Co, friendly and knowledgeable staff.
