1. can anyone w/ 37" tires and no lift and no s-charger tell me if they can drive 90mph on highway. im thinking of buying 37 bfg MTs , but drive far on hiways and need 90 mph, or at least 85

2. can anyone who has moved the air hieght sensors explain/detail the move

3. does anyone have a part# for the air height sensor?

Thank you
