#44 of 49 Michelin Pilots by smilingphases May 17, 2008 (7:22 pm)
I just bought a lovely Z4 and it came with 4 Michelin Pilots. The tires are awesome, after 2,660 mile trip no noticeable wear. Heavy rain and no hydroplaning! I treat this car like a motorcycle, so when winter hits, it is parked. Besides where I live, we get winter 8 months of the year and they don't even plow the streets so this poor toy car would be instantly high centered!

Personally, I drive the puppy 11 out of 12 months a year and love it. I lost maybe 5% grippiness by going with the Yokohoma equivalents, but I have to tell you, the grip better when wet, drive in all temps, last 50,000 miles instead of 20,000 and give a smoother ride. I've never been happier.   As for the low tire pressure light. It means you have a slow leak in one tire. You need to check the tire pressure regularly to determine which tire is you culprit. Get the leak repaired. If its too slow or near the side wall for them to fix, use a can a flat fix, maybe two, follow the directions on the can. I got an extra 10K after the first 20K by employing that technique. (another reason why I went with non RFT's for my first replacement set. Non-RFT's are easier to repair and about 33-50% cheaper for the same performance specs. I've heard both sides as far as whether RFT's pick up small leaks quicker. I think the tires wear quicker and closing on 20K miles, you find small leaks crop up frequently. Don't toss your tires so quickly though, sometimes the "slow leak" can come from a dirty/faulty staitor value. Good Luck

The tires are prone to pick up any small debris puncture especially if you don't like slowing down for the twisties. They hold the road like no bodies business, but the also are magnets for any kind of puncture material.   For non-run flats, probably not worth it. You shouldn't be pressing the limits as much, the tires are a lot cheaper to replace and repair. They shouldn't pick up the small leaks as quickly. Generally speaking, I always lose the damn insurance receipt for the tire repair/replacement and while I have purchased it several times in the past, only once have I cashed in on it and it was for repair only. So for me, it has never been worth it.   Incidentally, I have 7K on the Yokohama's and am in heaven. I did lose a hair off dry cornering hold, but made up for that in spades in wet and cold adhesion. I'm extremely happy with them (so far).

I know about as much aobut tires as Bev. Can you give more specs as to the Yokohoma tire and where I find them?
