Just purchased an 87 944 with unidirectional Pacemark tires "GT Radial" - phone dial wheels. These tires wouldn't have been my first choice, however they are new and seem to hold pretty well in corners and in plough through the rain. I don't even know who makes these tires. Anybody out there know anything about these?

 

These are Canadian tire re-branded tires.
Most tires bought through Canadian tire
are made by Goodyear or other major manufacturer
re-branded under the Canadian tire brands.
