It is common knowledge between T5er's who have 17" wheels that tyres are not widely available like for 16" wheels and there are less choices.

My T5 came on Michelin Pilot Premacy (around $500each) which I replaced at 37,000km with almost no tread remaining.

At 37,000km - Fitted Hankook DynaPro RA23 ($195each) and got 43,000km out of them, and if it wasn't for the puncture and small leak that caused one tyre to wear out on edges they could last 48,000 maybe even 50,000km. Frequently checked and pumped to 50psi (Van is fully loaded 1005 of the time).

Today at 80,013km - Fitted Kumho Solus KH15 ($237each)
I wasn't very pleased with the choice but I was told by 3 tyre businesses in Adelaide that Hankook RA23 is not available anywhere in OZ and I didn't want to wait 6 weeks. Anyway I checked some review of the Kumho KH15 today and this is what I found Kumho Tyres Australia Pty Ltd | PR Australian Rally Championships
After fitting them the ride is much quieter than on almost worn out Hankooks (otherwise RA23 was very quiet tyre and the noise was only from the road, not from the tyre tread).

Just an update; finally yesterday 06/09/2012 at approx 102000km, I've put GoodYear Cargo Vector 215/60R/17c on my T5. The first impressions aren't good. The tyres are noisy and hard, I had to drop the pressure down to 36PSI (from 65PSI) to get it to some acceptable level. The rolling noise is something to consider, if you thinking about buying them, and unless they last 70k-80k km, they're not worth of the comfort that is lost.

At 132800km for the second time I went with the Hankook RA23. It feels like I've just bought a new van, nice and quiet ride again.
So, what tyres are you using and how many km's are you getting?
