Tire size question for Murci
Hi, I'm the proud owner of a new to me '03 Murci. Need your help. I understand that the viscous coupling AWD requires one to stay very close to factory ratios. Looks like my tires are ok but I want to make sure I did the math right.
According to the sticker on the door, the factory size tires are 325/35x18 front and 335/30x18 rear. This yields a rear to front ratio of 1.059.
rear dia / front dia = [335x2x0.3 + 18x2.54]/[235x2x0.35 + 18x2.54] = 1.059
My car came with great looking chrome/black Maya wheels with sizes 235/35x19 front and 345/25x20. This yields a rear/front ratio of 1.052 which is very close to factory specs and within limits of normal tire wear. Should be no problem, right?
