2020 Ram 1500, currently at 10K miles. Tires are OE Goodyear Fortitude HT, 275/65-18. Wheels are OE.
For the first 4K miles there was no vibration at any speed, even up to 95 mph.
Starting at 5K, I noticed a light vibration when cruising at speeds above 80 mph.
At 6K, I performed Costco to perform a Rotate & Balance. The vibration was mostly resolved, but not perfect. The tech said each tire was out of balance by 1.00-1.50oz.
By 8K, the vibration returned and was very noticeable at speeds above 75 mph.
Earlier today, at 10K, I paid America’s Tire to road force balance the tires. Measurements were 9, 11, 14 and 18...which is within spec. However, again, every tire was 1.5-2oz out of balance. I have not driven the truck on the highway after the work was completed.
My question:
All tires appear to be wearing evenly and have 12/32” remaining. Why do these tires require constant rebalancing? I have not lost any weights.
