Four contact patches about the size of your hand determine if your car goes, steers or stops. This group is into the engineering of torsion suspension, air conditioning, engine heads, but "tires are all the same"?????????

Given how most old cars are driven, it's not that critical between decent designs because we are stressing the design so little. But especially in your Brand X, it's a big deal for safety and performance. Tread design , compound, tradeoffs (wet vs dry grip, grip vs wear, handling vs ride) matter a lot.
