2017 ES 350 Vibration at High Speed
 

Just purchased a used low mileage 2017 ES350. Decided to replace the tires which looked to be the original Touring Bridgestone EL 440-2 from the factory. I replaced them with Grand Touring Bridgestone Quitetracks. At 75 mph I start to get a vibration from the under carriage of the vehicle (seems to be coming from the front). The vibration doesn’t reduce or go away as I climb up in speed as I would expect if it’s ordinary tire balancing issue. Have had the new tires rebalanced a few times already, I think they are well balanced. The thing is I don’t remember any vibrations with the old tires. Thinking about returning these tires, but wanted to check if anyone has experienced something similar with this vehicle? Already paid to have them aligned, rebalanced, etc. Don’t want to waste my money!!
