265/35 is about 10mm too narrow for a 9.5 wheel (which is not the end of the world or anything) and also 8 or 9% too short. small.
275/35 (or 275/40) is a correct diameters and 275 is the typical width for a 9.5” wheel. A 265/40 would be fine, but possibly not a very common tire size?
keep in mind the XXX/YYRZZ number, the YY sideqall number is a percentage of the XXX tire width, so a 265/35 is shorter than a 275/35 even tho the YY sidewall number is the same, the sidewall and thus overall tire diameter on the 265/35 is shorter than the sidewall and diameter on the 275/35
That's what I figured, but AM has that 275 listed in their staggered tire set up?A 265 width tire is fine for a 9.5" width wheel. In fact BMW E92 M3's came with a 265/35/19 tire on a 9.5" wheel stock and a 10" wheel with the ZCP package (Competition). In fact Michelin recommends a 9-10.5" wheel width for a 265/35/19.
To the OP I would have an issue with those sizes as the front and rear difference in tire diameters is huge. A 265/35/19 is 26.3" tall a 275/40/19 is over 27.7" that will throw off the stability control in a big way.
Do not go 275/40/19 in the front and 285/35/19 in the rear. The front tires will be 1" taller than the rears, and will look silly. The stock GT PP1 front tire is a 255/40 on a 9" wide wheel and the rear is 275/40/19 on 9.5" wide wheel. You can put 255/40 on a 9.5" wheel. 295/35/19 in the rear (if available) would match better with a 255/40 or 265/40 on the front. If you go 285/35 in the rear, don't go more than 255/40 in the front.I've seen alot of aftermarket applications, mostly from American Muscle, calling for a 275 40 19 on a 9.5 front and 285 35 19 on a 10.5. Why wouldn't they suggest a 265 35 19 of the same aspect ratio for the front?
Maybe. 275/40 is kinda tall for the front. Depends on how low OP is up front or how much they like sidewall. My lowered S197 friend has 275/40 square on 19x9.5 and it’s fine, he likes it because it’s a cheap size with good selection. It’s mostly preference.275/40/19 on 19x10 offset 35 square is PERFECT.
I am tooThanks for all the feedback. One caveat, I'll be running Steeda lowering springs.
I don't know if it's the angle of this photo or what, but your front tires look like 18" with a really tall sidewall.265/40R19 & 295/35R19
Wanted to go with 275 up front but needed tires quickly and all they had. 275/35R19 up next.
That tire size calculator is great, especially the 2 tire comparison. I'm leaning towards 275 35 19 for the front. ThanksMaybe. 275/40 is kinda tall for the front.

I’m inclined to stick closer to the 27 inch diameter or less all around. A smaller rear diameter also gives a slight gearing advantage, where the 2018+ MT cars need all they can get.
