Hey guys recently bought some 305 50 20 nt420s used with great tread. Put them on and all week the truck has been shaking at hwy speed. I jacked the truck up and sure enough the front driver side tire seems to be out of round. I bumped up the pressure from 30 to 40 and it ridea a little better. The real kicker is that the tires say made in Malaysia. Any other nt420s guys that can chime in? Can this issue be remedied?
Tires are made all over the globe. Tons of Michelin tire are made in France and so on. I wouldn't worry about that.
I'd have the tires road force balanced. If the tire has excessive road force, they can spin the tire of the rim and see if it gets better. Most of the those fancy balancers can do a good job at fixing that or seeing if the tire truly is bad.
