Is it OK to ride with the same size tire (Goodyear Wrangler P245/75R17) with slightly different thread patterns? I want to use my spare as one of the 4 new tires, but the tire dealer states I can’t mix the threads, but it’s the same mfgr, model, and size. The current spare tire model is discontinued. In my opinion, this is not an issue. And I love the tire dealer; used them for 40 yr!
