Hi all,

1. In what way(s) can asymmetrical tires be rotated, as long as they are mounted “inside” in and “outside” out can they be rotated front to back and left side to right side?
2. Also in other-words if it’s asymmetrical is it automatically Directional or not?
3. The tires in question are Pirelli PZero Rosso Asimmetrico.

hi thai gi, im sorry i cant answer your question about tyres, but i was wondering if you lived in thailand or ever had.
i moved here a year ago on a three year contract and i have been atounded at the amount of replicated lorinser,amg and brabus modifications available.
if you are thai, i wondering if you knew any good tuning shops for MB'z and perhaps somewhere where i cant get mercedes bodykits. i don't care if they are aftermarket or real, i am desperate for a certain bodykit for my benz. thankyou.
i live in sathorn bangkok too.
-i hope you have lived in thaialnd or do now, or this reply is pointless!
anyway-thanks.

asymmetric is not necessarily directional.

* asymmetric tread - utilizes camber characteristics of suspension to take advantage of different inner and outer tread compounds and patterns (the Benz Carver prototype for example, takes full advantage of this, with special tires)

* unidirectional - the tread is usually designed to resist hydroplaning in one direction; some snow tires are unidirectional because they are designed to grip the snow as the tire rolled in one direction

If you think this makes rotation complex, look at the case of the Acura NSX: aside from being asymmetric and unidirectional, its OEM tires had asymmetric construction as well:

* because of their internal construction, the fronts tended to steer out, and the rears tended to steer in as they rolled. This design promoted stability and tended to negate any play in the chassis, which resulted in very sharp reflexes. All at the expense of tire wear.

for the NSX OEM tires, rotation was not possible.

Sir,

1. Let's take this to the Good MB Shops forum.
2. I address your questions there.

Sir,

What about the Pirelli PZero Rosso Asimmetrico?

Thai GI,

the Pirelli PZero Rosso Asimmetrico, as the name implies, is asymmetric, but not directional (the PZero Rosso Direzionale is directional).

i believe this is optimized for the driven wheels, with the side of the tread with longer curved grooves designed to be mounted on the inside part of the wheel. This means that you can rotate these left-right on the driven wheels.

I believe we should refer this to our expert Luke@tirerack.

The P-Zero Rosso is asymetrical in design and not directional so, you can rotate in any direction. What I would suggest is:


Front right to left rear
Front left to right rear
Left rear to left front
Right rear to right front


Luke

Luke,

1. It’s an honor for me that you’ve answered one of my posts.
2. Well I’m just researching right now but will be in touch after the tax return, you know how that goes.

Thanks for the knowledge,
