Anyone can post a poll including you. The problem is not everyone looks at the Tire & Wheel forum unless they are looking for those items them selves or are really bored.
From what I have read over the past 1.5 years or so, 225/50R16 tires fit on both E0 & E1 rims. Some people rub, some don't as no two Contours appear to be built the same, and neither are the tires. Choosing 225/50R16 tire for the OEM rim is a chance at rubbing that everyone must understand who purchases replacement tires for their SVT's. If you don't want to take that chance, stick to the 215/50 OEM size and pay mucho bucko and accept the limited availibity. If you are willing to take the chance at rubbing, then enjoy the selection. Just don't complain if they rub. Figure out what exactly is rubbing and fix it if possible.
IMO only, I'd take the chance with any brand/model of tire in 225/50R16. The KDW is a very good tire, but all others in the 215/50R16 are crap for my style, and how the SVT should be driven. But for $140ea, there are better tires in 225/50R16 size I'd pick, or save soem money and get a still good tire for under $100.
BTW, this forum does not support sticky threads.
