M5 real world 0-60 Time

There has been much debate over the M5's "real" 0-60 time. Not so much on this forum, but over the broader internet. I took a video of my stock 2001 to see what the beast could do. Recorded 4.89 seconds to 60 on the first run. Tires are fairly bald, so when new treads show up I'd expect a minor improvement. Enjoy!

Wouldn't bald tires improve the time as they are closer to slicks? (i.e. more rubber in contact with the road) I was under the impression the "tread" was for cornering and weather traction.

Nonetheless, very impressive. Any modifications?

What he said. Definitely not stock?

ah I guess I was wrong about the tread. Just came back from Thunderhill, and bald tires sure didn't help around corners, so I falsely assumed the same would apply to the straights. Maybe that's why I don't chirp as much during hard pulls as I did a few months ago. The car is 100% stock.

Serious? I thought exhaust note sounded very loud for stock

The video doe not show if it's uphill or downhill, nor do we know the accuracy of timing equipment. It's best to get a 1/4 mile time slip, that'll show both the car's power (trap speed) and driver skill (ET).

Bald tires do not mean they are more "like" slicks except maybe in appearance.

Bald tires mean worn tires that have a lot of heat cycles on them or are old. Used, bald tires that presumably have multiple heat cycles on them and are old (age) result in a tire that is harder than the new tire was therefore making it incapable of providing the same traction than the new tire did despite their drag slick-like appearance. Further, the lack of tread creates a dangerous tire that will not be suited for inclement weather or, especially, wet roads.

This hardening is also why some tires get noiser as they wear; because they are getting harder. There are also recommendations for replacing tires after they attain a certain age, regardless if they have ever been installed/used or not and despite remaining tread level, in order to minimize the adverse affect this phenomena has on the overall traction of a vehicle. How rapidly this change occurs is dependent on the type of rubber that is used in the manufacturing process and will therefore vary from tire to tire (manufacturer/type).

If they aren't R compound tires, slicks, etc., tires with the tread worn off are simply giving traction up, not helping it at all.

Learn something new everyday.

Can you explain why Tirerack offers to trim tread from some tires? Following your discussion above wouldn't that simply reduce the usable life of the tire?

Race slicks (F1 (when they were pure slick tyres), NHRA, CART) have tread in the contact surfaces of the tyre, this is why they have to replace the tyre as they wear. The tread on our street tyres is the same. As the tyres wear they loose friction at the contact patch. Less friction between the tyre and the road means less tractive effort which, results in slower straight line and cornering speeds and increased stopping distances.
