The issue with the 275/35/19 is the height, not the width. You’ll rub big time with even slight compression. Even 265/35/19 rubs until you’ve worn the tire down some. But you seem like the hard headed type, so give it a go and report back to everyone.

Also, you don’t need more than -2.0 in the rear on the M2 to achieve good wear. You’ll instead lose acceleration traction and slide the tire more and wear it quicker. And, you don’t need to roll the fender (again, $60k car!) to get the right fitment. I’m pretty much the guy that forced Apex to go to +45 in the rear bc I kept hounding them that their originally proposed offsets wouldn’t work for some 295/305s. I’ve been running +45 in the rear for a year.

But don’t listen to me, I’m just some guy that has no idea what he’s talking about after 40+ track days in his M2 over the last 2yrs.

Lastly, the OP was asking about tires to mount on his stock wheels. I gave the best answer to his question in the very first reply, vs all this 71R vs BFG Solo2, too tall tire, extreme camber, rolling fenders, aftermarket wheel discussion.

Appreciate the input...I don't even have my M2C yet....so all this is very informative...THX

I agree that the slip angles on the 2 tires are different and that the Bridge's are more forgiving at their rolling to sliding friction transitions.

But both these tires aren't even in the same league as a BFG R1 or HOHO A7/R7 for slip angles and feedback. I say that because both the aforementioned are 200 wear street tires and are much easier to drive up and over their limits than a R compound track only tire.

I state this from my own experience as well.... having over 200 track days in 2 different M cars and a EVO X over a 30 year period...

On R compounds both the M's liked 2.2-2.4 degrees in of neg camber in the rear with 3.4-3.7 up front. That was verified with both a pyrometer and a AIM SOLO 2 on HOHO's and BFG R1's. Also with a dialed in spring and C/O setup.

I'm sure those camber numbers will be lower on 200 wear street tires like the RE71R's.

I wonder if anyone has tried the 275/35/19's up front yet?

There are 2016-18 M2's on them in the 18" size...

I'm trying not to have to spend $'s on the Essex BBK kit if at all possible, but if what your saying is the case then that's exactly what I'll have to do next Spg, and buy some 18" rims and mount BFG R1's in 275/35/18's on all 4 corners. That should be a wicked fast square setup!

Keep the shiny side up!
