Tire wear question

It is quieter, stickier, and great in light-medium snow than your old Pirelli tires. In fact, even as the Pirelli Scorpion Zero A wears out....it was much quieter than my Michelin Diamaris.

However, that being said, if you are not going to drive your X5 in the snow, then I would get the Michelin Diamaris. They do ride nice....handles great and quiet when new. They have great wear as well.

BTW, your tires look like that they are cupped due to improper toe settings. I have gone through several set of tires in my past 151K miles of driving and I have never seen that kind of wear on my rear tires.

Also, BTW, the E70 X5 uses Michelin Latitudes as an OEM tire. The Michelin Latitude is NOT the same class of tires as the Michelin Diamaris.

The Diamaris are summer/street/sport tire. The Diamaris CANNOT be used in the snow....it is useless even in a a few inches of snow.

The Latitudes are in the similar class as the Pirelli Scorpion Zero Asimmetrico in that they are high performance all-season tires.

The Pirelli Scropion Zero A's seem to do better in the snow than the Latitudes.

The Latitudes probably will last longer than the Diamaris.

Since you had a bad experience with Pirelli, then I would point you to the Michelin products.

If it wasn't for the light snow I sometimes encounter, then I would go for the Diamaris (1st), then possibly try the Latitudes (2nd).

BTW, I am enjoying the Michelin Pilot Sports 2 on the ZCP Wheels on the M3. The tires are broken in now and they are nice riding, sticky, and great handling. I haven't had a chance to try them in the rain, but supposedly they are better than the PS.

Also, I would recommend that you might as well go back to the 255/50-19 sizes at all 4 corners instead of the 285/45-19. I think you'll have a better turn-in response with that size. With the 3.0i, you won't be able to break the rear end like the 4.4i. Plus, you'll probably have less tramlining as well with the narrower tires.

Also, if you notice, even the new E70 X5 4.8i, BMW has decided to stick non-staggered sizes for the 18" and 19" wheels/tires combo. Only with optional 20" wheel/tire combo did BMW go to the staggered set-up.

Actually, my 19" ZCP with Michelin PS2 are about 1-2 lbs lighter than the my 18" M3 OEM wheels with Michelin Pilot Sports.

I actually think the ride is better on the my 19" ZCP wheels with the new PS2. I think it is a combination of possibly ligher weight, but probably more due to brand new tires and that PS2 has slightly better ride than the PS.

Thanks for the advice. I was reading up on the Pirelli Scorpion Zero Asimmetricos and they seem to be well regarded on Tire Rack. There is a performance comparison article on The Rack as well and the Pirellis are considered a little old but still good. (LINK)The tire that stood out to me was the Yokohama Advan. Specifically, the dry braking distances for the Advan versus the Scorpion Zero was over 4' better in favor of the Advans.



All charts HERE.

I am actually really leaning towards the Advans. What do you think? I'm not liking the idea of going narrower. I sure like the wider look and more aggressive stance of the 285's.

That is the problem with all-season tires is that there is some compromise to allow the tires to work with snow.

The Pirelli Scropion Zero A is an all-season tire which does quite well for what it does.

However, since you won't be driving in the snow, unlike me who lives in an area that gets light snow sometimes and also our winter trips to Tahoe/Arrowhead, etc., you should try the ADVAN.

Just curious, why don't you like the Diamaris?

Also, since you have 19x9.5 wheels, you can go with either the 255s or 285s. The BMW OEM 19" wheels are 19x9 fronts and 19x10 rears. Thus, even though 285s would work on the 19x9 fronts, I found that the 285s on the 19x9 wheels made the sidewalls flex a little too much and soft for my taste.

Good luck with your choice. I am ordering another set of 285s to replace my rears and I will stick with the Pirellis because of the snow-factor.

Kev, the -2 camber setting looks really great....only problem is the uneven tire wear which you can minimize by playing with tyre pressure, only think is you constantly have to check the air. Haven't used the latitudes, but the diamaris look and feel great. Go staggered.

He doesn't have OEM 19" wheels, he has 19x9.5 inch wheels at all 4 corners.
