jnicoli Posted June 6, 2004 Share Posted June 6, 2004 i have a 91 LS4 and i put a 98 LS4 chrome wheels on it - went from 15-inch to 225/60/16. i noticed a 5% decrease in the odo mileage. 1. should i add 5% on my speedometer to reflect accurate speed? 2. would this cause any problems? skimming wheel wells? 3. anyone looking for a set of 4 good-condition 1991 original wheels with 95% tread on the Yokohama YK420 P205/65/15?
