They're "Z" rated... From Tire Rack "...While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed. 225/50ZR16 in excess of 149 mph, 240 km/h 205/45ZR17 88W 168 mph, 270 km/h 285/35ZR19 99Y 186 mph, 300 km/h Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below: 285/35ZR19 99Y 186 mph, 300 km/h 285/35ZR19 (99Y) in excess of 186 mph, 300 km/h As vehicles have increased their top speeds into Autobahn-only ranges, the tire speed ratings have evolved to better identify the tires capability, allowing drivers to match the speed of their tires with the top speed of their vehicle."

You're on 19s, correct?
The XL is extra load, that's all. I went +1 with Michelin Pilot SS. They're just 4mm ( 8mm total ) wider that stock. http://f30.bimmerpost.com/forums/sho....php?t=1069685 OEM = Bridgestone Potenza S-001 RFT FF 225/40/19 Diameter = 26.1", Revs / Mi. 798 RR 255/35/19 Diameter = 26", Revs / Mi. 801 ________________________________ +1 = Michelin Pilot Super Sport NON-RFT FF 235/40/19 Diameter = 26.4", Revs / Mi. 787 RR 265/35/19 Diameter = 26.3", Revs / Mi. 790 |

My only issue might arise when I try to do spacers....as I have about 4 or 5mm of extra sidewall now. I love the "meaty" tire look. |
