Oh no! Another tyre question. More of a technical question though.

"Prior to 1991, tire speed ratings were shown inside the tire size, replacing the "R" character. The available codes were SR (112 mph, 180km/h), HR (130 mph, 210 km/h), VR (in excess of 130 mph, 210 km/h) and ZR (in excess of 149 mph, 270 km/h). The ZR code is still in common use, often combined with a W or Y speed code."
I wish i knew what idiot started these stupid rumours on the internet. It's on par with the "no tax / mot invalidates your policy!!!2121312omfgbbq" crowd.

I'm not quoting an internet rumor. I thought about doing the same myself, so called the insurance company to ask. They advised I had to fit tyres to the manufacturers spec in the handbook otherwise declare them as a modification which resulted in a hefty increase in premium.
Which ST?? At that size, can't be Focus ST (18's), ST24(16's) or 200(215/45R17), so I'm guessing Fiesta? assuming std wheels.
Worth noting is that the extra width may cause the tyre to rub on arches or suspension, have a look to see how close your are at the moment.
I'd do it for the extra grip you gain.

Aye Fez ST mate. Just running std. suspension so there's plenty of room.
I'm going to do it as well.
Ahhhh so it's just the speed rating afterall. Excellent, thanks for that.
