So driving back inforth from athens to gainesville i started to notic that my car starts a little but noticible vibration in my car when i am at higher speeds (70 mph to about 80mph) when my rpms are around 2000 2500 umm so yeah any help might it be time to get the tires rebalanced idk yalls help would be great

also at a stop when i mess around with my windows such as putting them up or down my rpms drop slightly then shoots back to normal when i let it off any suggestions on that?

the rpm drop is just the strain on the engine from the window motors drawing more current its no big deal my car does it too(im assuming "slightly" is no more than 150 rpm)

i also agree its probably your tires wearing and needing to be balanced

if you can't remember the last time your tires have been balanced, then your tires need to be balanced.

your issue sounds like a tire balance issue to me.
