I'm on Tire Rack and need to make a choice to help a friend.
What's the *practical*
difference of 10mm wider tread?
1. This SUV is a dozen years old & has never been off road
2. This SUV is used like a car & never carries a heavy load
3. 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?
