Tires

[Hy Haberman]

My 2018 IS 300 came with Bridgestone Turanza tires, different sizes on front vs rear, so unable to properly rotate. Now, with less than 40k kms/24k miles, I need new front tires (not happy).

Can I replace the front with Bridgestone Potenza tires while keeping the Turanzas on the back ( for now)?

I would see no problems at all with using different spec tires as long as they are of the same speed and load rating

Yup, I'd have to agree with that. You also have to buy your tires from very reliable sellers, like 4WheelOnline. In that way, you could save a lot of money without having to sacrifice the quality of the tires.

Just been told that my Bridgestone Turanza tires are summer tires and the Potenza tires  are All season and can't have one type on front and another on the back. 

My real issue though is never being told when I first got the car,  in November in Toronto, Canada,  that there were summer tires on the car! I've never had summer tires on any car. Surprise, surprise!
