Michelin Pilot Sport Cup 2 or Toyo Proxes R888 R for BMW M3 E92 track days
This post is interesting for you only, if you are in the same situation as me:
Owning BMW M3 E92 ZCP
Having BMW Style 359 Competition Package Wheel Set (Front 19x9" ET31 BMW Part # 36-11-2-284-055, Back 19x10" ET25 BMW Pat # 36-11-2-284-060)
Doing track days
I bought additional set of Style 359 wheels (Front 9”/19”, Rear 10”/19”) for track use only. Prior to track day I take off my street set and replacing to track set. BMW tire recommendations for street are:
M3 E92 equipped with ZCP Style 359 wheels
Front: 245/35R19 Michelin Pilot Supersport
Rear: 265/35R19 Michelin Pilot Supersport
Notice that these are quite narrow sizes to these wheels.
M3 E92 GTS equipped with ZCP Style 359 wheels
Front: 255/35R19
Rear: 285/30R19
Notice, that rear setup uses 30 profile tires instead of 35 ones. And both F and R tires are wider.
Big question — what tires to use on track?
As these wheels are 19” and staged, there are not much a choice. Some recommend to go to square setup Front & Rear: 18x10.5" ET22 or ET27 with 295/30-18 tires.. There is much more choice in 18” sector, brands like Nankang, etc. I chose to keep staged 19” wheels, what limited my options. What I have found:
Michelin Pilot Cup 2
Front: 255/35R19 (96Y) XL TL Michelin Pilot Sport Cup 2 (€ 240.84)
Rear: 275/35R19
Michelin Pilot Sport Cup 2 setup
Front 255/35R19 (96Y) XL TL Michelin Pilot Sport Cup 2 €240.84
Rear 275/35R19 (100Y) XL TL Michelin Pilot Sport Cup 2 €312.58
Total for 4 tires € 1,100
Toyo Proxes R888 R setup
Front 265/30R19 89Y (GG-Medium) TL Toyo Proxes R888R €240.46
Rear 295/30R19 100Y XL (GG-Medium) TL Toyo Proxes R888R €260.40
Total for 4 tires € 1,000
As you see, I went for pretty agressive width and profile with Toyo — simply because this was the only choice. Good news is that they fit perfectly to 9” front and 10” rear wheels. In Michelin Cup 2 setup, I chose 255mm front and 275mm rear tire, cause factory 245 and 265 are seriously narrow for these wheels. Interesting, that BMW even recommended these sizes.
Which setup to choose — price difference is only 10%, eg 100 €uros? I picked Toyo setup because:
Lasts much longer, has more contact area and less stress
Is cheaper to buy, much cheaper to run
Looks better
Negatives:
Toyo Proxes R88R is street legal, but a bad choice for everyday driving, they are too noisy and wet traction is sub-optimal.
