Damaged lawn - security deposit?

[Patrick Rose]

I have a SFH and my first tenants will be moving out this fall. He often parks his truck where the tires are off the driveway and in the lawn. Now the lawn is flattened and the grass is dead in the spots where his two tires sit alongside the driveway. It's a small driveway and they have two large vehicles, so I see how it happens. Is this the sort of issue that constitutes funds from the security deposit at the end the lease? I'd like the lawn to be back the way it was when they moved in so it shows better for the next renter. Thanks for any advice.
