Replacing tires on AWD cars
Supposedly this is because slight differences in tire diameter can cause Haldex clutches to remain engaged and thus overheat.
Anyone know if this applies to AWD systems that do not use the Haldex system such as the Quattro IV on my '98 A4?
As it so happens I did replace all four when one of my Goodyear F-1 Steels got a cut sidewall and I found out that Goodyear no longer makes replacements.
This information appeared in the Technical Correspondence section. I believe it was the June 2002 issue.
