But wait there is more. It's hard to see in 2-D photos but since you have the tires , look at the sidewall of the Maxxis. It's sort of rounded and the tread contact patch doesn't really make it to the edge.
In comparison , the Bridgestone tire shoulder is squared off making it so that tread goes ALL the way to the edge of the tire. This is part of why I took the photos of them laying down next to each other.
The width of tread that actually makes contact with the ground on the Maxxis is actually less due to the shape of the tire... indeed making the section width much greater than the tread.
At any rate .. whether it's .5" wider or .75" wider contact patch per corner ... the clear thing is that you are getting a LOT more rubber to the ground with the Bridgestone R1 than the Maxxis. That's hella important when trying to avoid wheelspin at the rear and also with trying to avoid having the tire roll over on the front when cornering.
The Maxxis have been hard for me to kill but when I do I will go to Bridgestone RE on one set for Autocross and driving to track and the BFG R1 as my track set.

I have been through more than 6 different tire set ups on track in my M2....a local shop let's me do some testing! I prefer the 18 square, using TR 18/9.5 wheels. The Maxxis RC1 275/35 run "fat"... need a bigger spacer, more likely to rub on compression and not as big a footprint as others. The Hoosier R7 in 275 has a better contact patch and grip but may still rub slightly without a 12mm spacer.
The RE71 in 265 square is a great all around tire, wet or dry, but several seconds slower. My overal favorite is the BFG G-Force R1 in 265/35, it fits without issues ( still using a 5mm spacer in front), has a contact patch equal to some 275s, wears well and gives me great lap times.
