Wheel shake

I purchased SCS Ray 10’s +25 offset and mounted BFG 285 65/18. Had them mounted at my local tire shop. I now have wheel shake. Worst is around 60mpg. Seems to not be as bad at 70mpg but it’s still there. What do you guys think is happening and how to fix it????

 

Make sure the wheels sit flush to the wheel hubs. The next thing would be to balance them on Road Force machine: https://www.discounttire.com/learn/road-force-balancing The last thing is to replace a shaky tire.

 

I just had my tire place mount my new F5 SCS wheels. Barley took any weights and no road force balance and they are perfect with the steering wheel. Sometimes they need to be road forced balanced.

 

BFG's are noted for having balancing issues. Start with a rebalance or ask for a road force balance as recommended already.
