Anyone having problems keeping their tires balanced on their 5th gens? I know this is a stupid question but, the only problem I've had with my 2010 SR5 is horrible vibrations in the steering wheel and throughout the vehicle at speeds starting at 60 to 75 mph. I purchased the runner used with 40xxx miles on it with a set of Nitto Terragrapplers on it that looked great with ample amount of tread left. it vibrated and no shop could fix it. so I traded the tires in and got a set of TOYO open country AT2. fixed the problem until I rotated the tires at 5500 miles and the vibration is now back and just as bad as before. the tires aren't cupped or anything. it's at the tire shop now getting looked at. i'm just aggravated that my other vehicle which is 15 years old rides better on the interstate than my runner. still love it and wouldn't trade it for nothing but still aggravated. it's not like these tires are cheap off brand tires.
