E63 / E64 6 Series (2003 - 2013)
The E63/E64 BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations.

Mein Auto: 650i
Need help with tire selection

Just got some OEM M6 rims to put on my 2007 650i. The recommended tire spec is p245/40R19 on the front and p275/35R19 on the back. I found a good deal on Michelin PS2's at Costco but then ran into a problem. The original PS2 that meets the recommended load rating for the rear tires has been discontined. The tire guys said the thing to do was put the XL 98Y on the front and XL 100Y on the rear. My understanding is that the XL is the 'extra load' tire. It sounds OK, but I'm worried that I'm going to spend $1500 and somehow these will be incorrect for handling or appearance. Has anyone had any experience with these tires?

Don't buy your tires at Costco. Go to tirerack or discount tire.

Just get the Bridgestone Potenza RE050A run flats, or non run flats if you don't think you need a run flat, from the Tirerack in the sizes you describe. That's the OE on my 650i sport package. They are great and designed for the 650i. They will be around $1500-$1600 for all four.

I have the PZero's, take a look at them and stay away from places like Costco for tires. Shop around, a good tires shop will match a price if you find it somewhere else cheaper.

Why does it matter where you buy the tire? Isn't it the tire that makes the difference?

There are Tire Shops and there are Tire Shops.
I could be wrong but I don't think Costco see's many 6ers.
Deal with a shop that's use to seeing your kind of vehicle. They will have the experience to suggest and advise you on tire selections and then stick with them.
And like I said, they should match or beat anybody elses price
