Modify vehicles with off-road tiresThe tires recently arrived in Fortnite and allow to change car characteristics, making them All Terrain and therefore much more maneuverable off the road, which is rather a good thing. However, for this, you are going to need two things: tires and a car.
The tires are everywhere, like almost any loot. It will therefore not be difficult to find some, but we recommend that you go to a garage (see map below) since we find some easily in these places, which should allow you to find some even if a player has already passed before you. We also find many cars in these places.
Once a tire and a car, grab the tire, click as if aiming with a weapon and throw it at the car. This will automatically transform into an all-terrain vehicle, being much more maneuverable off the roads. It is therefore better to modify vehicles with off-road tires if you have to drive for a while.
As you will have understood, this is a relatively simple challenge, provided you have a tire and a car.
