I currently have a set of Michelin MXV4 Plus XSE P205/65R15. Two tires are worn out and need to be replaced. What would be a recommended substitute for the original tires without going over $100+ per tire? A guy at the tire store suggested going with a Pirelli brand because it’s cheaper and have a better tread life (70,000 mile). He didn’t mention the name of the tires but quoted at $75 ea. Will it be okay if I replace the two tires with another type or brand of tires instead of the original tires?
