Yokohama have a new tyre out, sorta new but anyway it's the successor to the A048 called the A052, comes in sizes 315/30/18 and 255/35/18 or 245/40/18. I'm unsure if anyone has tried these but they're meant to be an amazing tyre in all conditions and was wondering on sizes for the GT3.

Currently I run a 295/30/18 and a 245/40/18 without any problems but was looking at going bigger in the rear soon and if the 315 and within spec it might be cool to try out. I have seen some guys talk about this calculation to see if tyres are within the 5% safety but don't know the math myself. What is the calculation to see if these will work out, thanks!
