Michelin Pilot Super Sport 265 vs 275

I researched the hell out of this and debated for a while before deciding to upsize from the 265/35-19 to the 275/35-19. There is also another thread around here discussing the difference in weight (3 lb each) and the amount of rubber. I figured I'd snap the pick below to show how dramatically different they are. I had previously bumped the front up from 245 to 255 and definitely noticed it behaved better when entering a fast turn (street, haven't tracked it). It will be interesting to see how it feels when I go from a 255/265 setup to the new 255/275 setup. I suppose I'll have more understeer with the increased stagger.

Anyway, here they are. The 275 above is mounted.

And before anyone asks, I'm standing behind the 265. In person it is obviously more narrow, the pic is deceiving.

That 265 is brand new btw. The car was in an accident and the body shop refused to let me put larger tires on the rear. They would only mount what it came in with. So when I took possession I pulled the wheels and brought them to Discount Tire to get a new pair of tires, leaving me stuck with a new 265 and a used one with 7/32 of tread left. Not sure what the hell I'll do with them.

Does anyone have any pics of how 275 looks on the stock width wheels?

There are a couple of versions of this tyre....is this the BMW * 100Y load version?
I think there is also a 96Y and a 100Y version without the * designation.
Just wondering why the rain channels are so different.

I've had all kinds of acceptable alternative sizes and the stock sizes are better all around.

Going up in size, they make a step change in block width, but I thought that occurred at 255s. I have the PSS in 255/35-19 and 275/35-19, and the 255s have the smaller block size like the 265 pictured (and hence larger tread channels), so I guess that switchover occurs at the 265 width.

I find that surprising. BMW even went with 255/275 on the new F8x M3/4 on the same 9" and 10" wheel widths as the competition package wheels on the E9x M3.

245/265 is probably fine for the 220M wheels, but is too narrow for the 359M wheels.

The new car is completely different. They designed the F8x and tested it to run those tires. As they did with the E9x.

I tried the PSS's in 255/275, there was a difference in feel and looks. I liked the looks but the stock sizes felt the best. I did not find stock size PSS's lacking for grip at all. Stock sizes for me on the street. Function > form.

Ah, I have mine on 359's. They basically "fit" the rim. The 265's were a bit stretched.

I really doubt that it makes that much of a difference. Remember that the ZCP cars sit 10 mm lower and have wider wheels, yet use the exact same tires as the non-ZCP. If the different car setups dictated different tires you likely would have seen it with the ZCP but you didn't. More likely BMW had a shit load of 245/265 PS2s on hand per their contract with Michelin and slapped them on every E9x M3 that came off the line, come hell or high water.

This is exactly what America's Tire told me. I was forced into upsizing by an unfortunate flat during a localized backorder of 265s. Going with 275s was on my mind but I hadn't decided yet. An estimated 2 week delivery made the decision easy. Now I'm running 245/275 with 15/12 spacers I'm going to 10mm in the rear soon to calm things down.

The 275 just looks better on the ZCP wheel. I'm getting test pipes and a tune to offset the weight increase
