My 97 jeep cherokee front drivers wheel staggers when at speeds of 45 to50. but it stops around the speed of 60

Hi there ,this is a tyre problem we in the business call an "out of round tyre" to find which tyre it is so you can replace it ,go to each wheel and feel around the tread part of each tyre with your bare hand laying flat on the tread and feel right around each tyre ,you will find the problem tyre quite fast using this method as you will feel a raised bit on the bad tyre thats making your steering wheel shake ,a reputable tyre shop could do this for you if you dont feel capable ,then have the tyre replaced and ask them to balance all your wheels in the processand THANK YOU for using FixYa !!!
