i have run 452's on my ibiza.... and they are not that good. Not remotely as grippy wet or dry to bridgestone s03's
cheap as chips, but you do seem to get what you pay for.
245-35-17 452's being physically 10mm narrower than my 235-40-17 SO3's too..
Compared to Eagle F1 or Toyo though Bill, not sure how much those Bridgestones cost ... could this also be weight related? I'm guessing the Ibiza is a fair bit lighter than say, my Leon Tdi?
From what i've found on normal road surfaces and doing a mix of driving ... they certainly don't seem any worse than either of the other two tyres i've had and they're almost 30 quid cheaper.
