When you have a blowout it's always better to have the blowout of the tire on the front of the vehicle.
When you have a blowout of your tire on the back of your vehicle it can cause fishtailing and make your vehicle harder to control especially if you are driving at highway speeds.
If the blowout on the vehicle happens on the front of the vehicle it's easier to control because as long as you have a firm grip on the steering wheel you can more control the vehicle by keeping your hand on the steering wheel and keeping the vehicles tires straight.
When you do have a blowout on either of the tires you should not panic, don't slam on the brakes and just gradually slow down by slowly removing your foot from the gas pedal and then as you slow down move your foot to the brake pedal and press on the brake pedal slowly.
