Re: good tyre price
I fitted a set of these to a 3.0MV6 omega they were 235/45/17.
I thought they were excellent value for money and gave as good traction in both wet and dry as some much more expensive tyres I've used in the past, I don't think you will be disappointed with them. I bought these after using KU15's on my cosworth which are a race compound tyre designed for road and track use, these where possibly the grippiest tyres I have ever experienced in the dry and where still pretty good in the wet.
Back to the KU31's, I would recommend them to anyone how wanted a good stable set of tyres for reasonable money, the grip was better than expected as was the ride and tyre noise was low the only thing I would say is be careful for the first few miles as they where like slicks in the wet for about 20 miles.
Hope this helps.
