The Hybrids have 15" wheels with 195/65-15 tires. Your LX probably has 16" wheels with 205/55-16 tires. So, you'll need new tires with the wheels (if the tires with them are no good), and your speedo will be a little off. That's a big investment with a long cost recovery period.
I'd max inflate my current tires and call it even. When the tires wear out buy LRR tires.
