stock size is 285/60/18. i need to get new tires. there are limited choices in this size. many more options for the 275/65/18. im thinking geolander G015, which is 40$less per tire for the 275/65 vs the 285/60. my question is, " would there be any reason to keep the stock size-285/60, aside from the speedo being off. is there any on road handling/performance compromise with the 275/65?
