Thanks! All insight. All 4 tires are the same Goodyear series. The fronts show very minimal wear. Rears new. I checked tire pressure, driver's rear was about 40.5 and the passenger rear was about 42.5. I brought them both back down to around 38. I haven't driven it yet. That will happen tomorrow. The slicks in combination with stiff sidewalls, vs more traction and softer sidewalls sounds just like what I saw.
