Yes, you can replace a P245/70R16 106H tire with a P245/70R16 106T tire, as both have the same dimensions and load index. The difference lies in the speed rating, with the "H" rating allowing for a higher maximum speed than the "T" rating. However, using a tire with a lower speed rating may affect performance, especially in high-speed conditions. It's advisable to consult your vehicle's manual or a tire professional for the best recommendation.
