255/275 Tire Size and Specs Comparison
I'm a relatively new owner of a '21 M2C and have read a lot on tires, wheels, etc. I concede there are so many others on this forum with greater tire knowledge and fitment expertise. I have 19" EC-7 wheels from Apex in M2C friendly offsets. We all know there limited tire choice for the 19 wheels and I don't want to go with 18" wheels given the obvious costs involved. At the moment, my car will ride on stock suspension but coilovers and camber plates will be on the car in the near future. I did some research online and wanted to share simple comparisons on size and specs between different tires. Based on the information and my daily use with a few HPDE days every year, going to a 255/275 setup seems like a good option given I keep more sidewall on the car, the rev./mile is close to stock, and minimal change in other size specs. When you look at tire specs for 255/275 plus size option, interesting differences exist with weight, tread width, and tread depth. All considerations in addition to how sizing impacts rev./mile. Maybe others can review and comment based on their experience and decision factors. Hope this is helpful to some.
NOTE: If you find any errors in the numbers, let me know and I will correct. Basically getting this online. Know that there are so many other tire choices so I picked the ones I'm interested in or have experience driving on with other vehicles.

Interesting comparison... as I prefer not to have the revs/mile differ significantly as well. Only thing I noticed was the rev/mile on the 275/35 super sport 4S' should be different than the OEM super sport size? Since they are different overall diameters...

The 4S and Cup2s don't really give you aditional width in these sizes.

I did the whole spreadsheet thing as well when I was getting new rims and tires. HRE wanted to know which brakes, the exact tires [model & size], which coil-overs and how far I was going to drop before they built.
I ended up with MPS4S 255/275 35 series on rims 19x9.5 ET25, 19x10.5 ET40. I have found these new rims/tires perceptibly softer than the stock rims/tires. |
