Tire and Wheel Measuring

Very reasonable!! I did something similar.... BUT while tire mfgrs list thier tire specs as accurate there is room for variation and there usually is variation. some in their specs some in your efforts and some in the car itself.......if you are ordering these tires online....visit a local store and try to find a set of used tires in the size you seek BEFORE you order....put them on the rims then put them on the car...BOTH SIDES one at a time is OK...but fit the new shoes before you buy...especially if buying/ordering online. Many many stories of tires beig bought online that you are now stuck with because they are not exactly as specified due to rim width, run specs who cares!!! if they dont fit they may as well be SQUARE..... fit the shoes before you buy
good luck
