I'm on Tire Rack and need to make a choice to help a friend. What's the *practical* difference of 10mm wider tread?
- This SUV is a dozen years old & has never been off road
- This SUV is used like a car & never carries a heavy load
- What matters to the owner is economy & safety
From the standpoint of economy (e.g., miles per tire), I don't know if a 10mm wider tire will last longer or shorter. Do you?
From safety, I "guess" that 10mm more of tread width is safer, but the driver is a little old lady (literally) in a no-snow state, so, traction isn't really a problem.
Any idea what's best?
Stock OEM is 225x75R15 Current tires are 235x75R15 but I'm replacing all four.
What difference (practically) does 10mm make?
