Tire size question/concern
I'm in the process of adding 20" wheels to my car and was looking for some info regarding sizing and diameter. Based on the tirerack website the stock 19" tires have a diameter of 25.8" front and 26.3" rear. If I go with a 275/30/20 front, the diameter increases to 26.5" and a 295/25/20 rear the diameter goes to approx. 25.8" rear. Anyone know is this will create and issue?
I could go with a 255/30/20 front and 285/30/20 rear and the diameters are 26.1" f and 26.8" rear but I'm concerned about increasing the diameter on the rear as it will reduce acceleration a bit as it will increase the effective final drive ratio. Any suggestions?
