Can you replace a p255-70R16 with a p245-70R16?

Yes, you can replace a P255/70R16 tire with a P245/70R16 tire, but there are a few considerations. The P245 tire is slightly narrower than the P255, which may affect handling and traction. Additionally, ensure that the change in tire width does not interfere with your vehicle's suspension or wheel well clearance. It's best to consult your vehicle's owner manual or a tire professional for advice on compatibility and safety.
