And here's a photo of how the mount fits in the car:

When the rubber breaks, as has happened to the mount in the photos, the transmission can sometimes flop around just a little bit. Mine did. Your description of the shudder leads me to suspect that it happens when the torque converter is locked. With the driveline in such a rigid state, without the TC 'slippage' absorbing the shocks, I think that a broken mount could absolutely be the cause for your vibration.
That being said, replace all four tires and rotate them often. It's important that you maintain the same circumference between the front and rear wheels.
Anyway, the mount isn't that expensive. I would expent a couple hours of labor to install it, as you have to remove the exhaust system to get to it.

Does the torque converter lock up at 40-50 mph? I thought that happened at 60+. The shuddering happens at speeds lower than 60. The tires are the same size btw. From what I read on them. They have pretty much the same amout of tread too even though the back ones are worn a bit. I can't really see any less on one than the other.
