Is this going to be a problem on my 1M?
Not ideal on paper but I doubt there can be any real problems. Think this way; the same PS2 tires were used on M3 which is quite heavier than a 1M but they shared the same load rating tires. Why? Because it is easier and cheaper to keep just one tire in stock for similar models for factories even if they weigh differently. Now, under normal conditions you shouldn't have any issues because even those new ratings should cover your car's weight.
There is one possibility though, if you track your 1M heavily under certain conditions there will be extreme weight transferences on one or two tires. That comes to mind.
I was very curious about that new Goodyear too, they should be good in wet. Not sure if they are a perfect choice for 1M but if you try them you can tell us.
