I wasted 5 years of my life in a tire shop, but one thing I learned was to get the bigger/heavier tires to balance it took some effort on my part; many times I broke-down and spun a tire on the wheel say 120 to 180 degrees then re-inflated and re-balanced until the max. weight per side was 3oz.
These bigger tires and rims have "heavy spots", if you donÆt believe me try taking one that has say 9 oz. (3- 3oz.) of weight on one side and spin the tire on the rim 180. Most times you'll love the results. The problem is finding a shop that will care about your problem.
Once these tires are balanced correctly, youÆre done for life with a good 5k to 8k rotation.
Good Luck
