Been running GT GDM 635's several years. They work well w8th my application pulling around in muddy , snowy, sometimes hilly farm yards. Get a couple years out of them and replace. But...a few days ago I had a set of 4 put on my rear drive axle (where my locker is). Moved a set of toyos that I'd bought back in may to the front axle. As well replaced my xza3's on the steering with the xline energy's which are the replacement tires. Now I've got a terrible shaking at highway speeds. Trying several things to diagnose it. Can't imagine it's the Michelin's, but shouldn't be the gt's either. The gt's stand an inch taller than the toyos but the power divider should be able to manage that I'm thinking. It's a head scratcher. 40+ years of trucking but you can still run into weird crap.

 

That's probably messing with the driveline angle between the axles, hence the vibration at highway speeds.
