They replaced one of my tires with Bridgestone, and I asked if it was a problem, they said no...then the next time I had a tire problem they said I couldn't mix tire brands. So I was like.. hey you guys mixed the tire brands the last time. A that point, I had one tire with 58K which needed to be replaced (original tire!) and one with 38K, one with 30K and the new Bridgestone with 8K.
I knew you shouldn't mix mileage left and right, and brands left and right...
I was like guy...s this is a mess, and you had replaced each tire as I needed.
So the Lexus dealer replaced all tires with new Dunlops for $149 (incl. mount, balance and alignment), I considered that a deal.
