I received a set of chrome OEM XLR-V wheels for my birthday and bought a set of the Pirelli euphori@ tires for them. Three of the rims and tires balanced with minimal additional weight added. On the fourth tire/rim they had to add 4.5 ounces of weights. It's also a front tire and rim. Does anyone have any experience with this much additional wheel weight on their rims? Does it seem reasonable to add that much weight. If I were to have the tire shop dismount the tire and rotate it 180 degrees from it's current position on the rim, think that would make a difference? I've got to believe some of the imbalance comes from the tire and some from the rim so maybe if I moved the tire 180 degrees from where it is now, that might cause the tire and rim imbalance to cancel out. Anyway, does anyone have any suggestions? Any concerns about running with that much additional weight on a rim on a steering tire? Thanks in advance.
