Well 5 months on and 6,000 miles later I’ve just replaced the back pair of 275/30 19 SC7s….
As you can see the originals were down to the 1.6mm tread wear bar..obviously long past the suggested 3mm replace limit..
So the good news…
Much better feel than the Michelin MP4S…steering much more communicative…you can feel what the front end is doing.
Prodigious grip in both dry and damp / moist roads…never ever slid and only spun a little if applying 400 BHP in first and second.
Seemed quieter to me and Andy McD when compared to the MP4S
The as expected..
Ride comfort more or less on a par with MP4S
Not so good
Very bad trampling when admittedly worn much past their official replacement limit
Very bad in wet conditions when worn, but again, given the width and wear maybe not surprising.
The tramlining got in part may be due to quite large increases in camber..I plan to back those off next week.
With these weekends run forecast to be wet at times thought it prudent to put next seasons rears on…what a transformation…almost no trampling and cope with quite remarkably deep puddles.
Premium rubber at a premium price…wear rates are I guess what you pay for to have enough grip to contain 400 BHP of E89 being flung around..interesting despite a lot of camber evev wear rate…so must be going round corners to wear evenly..
