Robert!
Mixing assymetrical with normal is no problem, but you are not sure the
rolling circumference is the same, even if the tyre has the same dimensions.
Last year I was struggling to get som new rear-tyres(325/30-ZR18) and wanted
to step up a bit on the front to 265-275/35-ZR18. I had to choose between
Pirelli and Michelin and to my suprise Pirelli had 4 different pattern to
choose between(Assimetrico,Rosso,Nero and a fourth I do not recall the name
of). What surprised me was that all had different diameter(and of course
circumference) with as much as 10mm on the diameter, all on the same
265/35-18 dimension! I called the tech dept at Pirelli and yes the guy told
me that they were different because sometimes the
factorys(Porsche,Merc,Audi) required special sets with different dimensions
front/rear for their cars. His advice was to roll each tyre one revolution on
the ground and then measure, to get the best ones for our quattro systems.
I am not saying you are in trouble Robert, but I would propose a measurement
before closing the deal. Please give a feedback on the result.
Best regards Joern,MTM RS
