What sizes are your LMs? My LMs are 8.5 in the front and 10 in the rear. I'm going for the 235 / 275 setup next time I need tires.
My current 225 / 265 setup looks a little bit stretched. More meat will look better and the wider tire is welcome. Only bummer
is the larger diameter slowing the acceleration a little.

Tire fit will depend on multiple things
wheel:width & offset(ET)
Tire: width & height(OD)
suspension: ride height & specs
I try to keep front and rear tire OD close to the same spec as it simplifies setup & alignment, for that reason and for favorable track handling 225/40 & 265/35 or 235/40 & 275/35 or 245/35 & 285/30 on 8ET52 for 225/40 or 8.5ET54 for 235/40 & 245/35 w/ 10ET65 for any of the above rears. For A/X the tire selection would be a little different.
The above work at any ride height, I do use much more negative camber than spec but any track car will want that as well.
Here's what the stock fit looks like compared to a max fit 245/285, 235/275 would fit on either wheel set and be in between, I sort of dislike the 235/275 because of the tire height which saps performance a bit.
