As for your question of a tire that is measureable to the RE040 I would try out the potenza RE750. It's performance matches the RE's but lasts more than twice as long. the tread wear is 340 as opposed to the RE's 140. Plus they're not as expensive as your OE tires. If you're looking for better performance than the RE's I'd go with the Potenza S0-3 Pole Positions. They might be a tad more expensive than the RE040's but they are definitely worth it. I have them on my G and i love em. They will last you about 15,000 miles on average with a treadwear rating of 220 and they are grippy as all hell. The S0-3's are Bridgestone's 'Platinum' performance tire whereas the RE750 is 'Gold' performance tire. I think the RE040's are also rated as 'Gold' in our system. If you have anymore questions about Bridgestone tires i'd be happy to help
