Hello - I just changed had my first tire change for my 2010 LR4. The original tires were Continental - but I went, at the recommendation of Mavis Tire in Riverside, CT, with Pirelli Scorpion Verde - Extra Load tires. Since the installation of the new tires, I'm getting a vibration in the steering wheel that wasn't there prior to the change. I seem to notice it between 40-70 MPH the most. I brought it back for Mavis to re-balance - but that made no difference. Wondering if these just aren't good tires for the LR4? Maybe there are some Land Rover-specific adjustments that the Mavis tire people aren't aware of? Any suggestions?
