How aggressively do your drive your Crossfire, how many miles do you drive each year, and in what weather conditions? The tires on the crossfire are fairly wide, and all the tires that match the original sizes on your car provide more grip on dry pavement than all but the most spirited driver will ever need.

The Goodyear F1 GS-D3 is priced attractively and has a really good-looking tread design. I will consider getting them when I need tires. However, since they have a "highly" directional tread pattern they may be more prone to uneven wear and noise. But they sure look good.

One thing to consider about the Bridgestone Potenza RE 050 is that it has the lowest UTQG treadwear rating of the bunch - just 140! The Michelin Pilot Sport PS2 is rated at 220 and the F1 GS-D3 is rated at 280. Based on those numbers (which are provided by the tire manufacturer from tests conducted against a standard) the Goodyear would be expected to last twice as long as the Bridgestone. So if your car is only driven a few thousand miles a year, the Bridgestone tires may still be a good choice, otherwise you can expect to replace them more quickly.

If I were buying a tire today and I routinely drove my Crossfire aggressively on dry and wet pavement and didn't require the absolute quietest ride I would get the F1 GS-D3. If I was a more conservative driver or even thought I might be forced to drive in snow some day, I would consider the all season Continental ContiTouringContact CW95 which Tirerack is practically giving away (< $500 for 4 in the U.S. - don't know how much they may cost to those in the UK). If I was looking for an inexpensive summer tire that would still provide good performance I might even take a chance on the Avon Tech M500. Only if I drove less than around 7K miles a year would I consider the Bridgestones based solely on the treadwear rating. I probably wouldn't consider any of the Michelin tires solely because of price. But if performance is the goal, the original equipment PS2 is hard to beat.
