81 SX4 vibration at around 75mph....Solved!!!

That means that my car's vibration is probably also from old tires.  The tires on it are over 10 years old, but they also only have a few thousand miles on them.

Yup. You have to lift the car off the ground on axle stands to prevent the steel belts from kinking from sitting in one position too long with weight on them.

ill tell ya what, it sure makes a world of difference...Not just in the ride but the steering, the road noise and the breaking have all improved with the new rubber...Id like to say I learned my lesson but Ill probably continue to drive around on tires that should have been replaced a decade ago....hey, ya cant fix cheap

Your line about "you can't fix cheap" is so true. I bought three new tires for a 95 dodge truck to match the brand new spare. Worst tires I ever had. Years of driving a nice truck that drove like crap just because I was to cheap. I replaced all 4 with a good set. Wow what a difference, ride, steering, traction, vibration. The bad tires where Mastercraft brand the replacements where GT Radial brand. I hope that fixes my "cheap" problem. Actually I like to use the word frugal. Sometimes you have to look past the price and think long term. Old age will do that to you because you want to fix it once and not keeo messing with it. Thanks for the laugh!

I'm a sucker for saving a dime....even if I spend a dollar doing it  I come by it honestly though, my grandfather was a restaurant owner who would save the strings off of worn out aprons to be used as shoe laces for my dad and his brothers....my poor dad peeled shrimp and chopped onions from dusk till dawn for $3.00 a day...Dad says he can still smell that stuff on his fingers 50 years later.
