Right on the Lexus web site it says,
"Tires fitted with 17- or 18-in wheels are expected to experience greater tire wear than conventional tires. Tire life may be substantially less than 20,000 miles (17-in) or 15,000 miles (18-in), depending on driving conditions."
Are you kidding? Does that mean if you get the Sport Package, which comes with 18" wheels, and you drive the car like it is meant to be driven, you are going to get about 10,000 miles per set of tires?
Just taking a look at the tirerack website, it looks like it is $925 just for the 4 Dunlop SP Sport Maxx tires, then you have to have them mounted, balanced, etc.
Oh, and don't you need a full 4-wheel alignment every time you replace the tires since they are different sizes front and rear, and I think you can't even rotate them side to side?
Are you going to have to spend WELL OVER $1,000 every 10,000 miles for new tires for this car, as if it isn't expensive enough to start with?!?!
Oh, and since these are SUMMER performance tires, at about 10,000 miles are you going to be slippin' and slidin' whenever there is the least bit of rain?? Do you need to change them at even lower miles?!
I drove the IS 350, I love it, but I do real estate and put over 30,000 miles on my current car last year. If I buy this, do I have to budget another $3,000-4,000 just for tires every year????
