Anybody running this set-up?

I see the 295/40 is between 1/2" - 3/4" taller than the 275/40 (which is the same height as the OEM 245/45 tires) - will that height difference be a problem on this staggered set-up?

The difference in diameter will affect the speedometer accuracy if the car is 2014 or older. 2015 and up use the wheel speed sensors to calculate speedometer though, so it shouldnt be a problem, that I’m aware.

Shouldn't that throw an ABS code if the front and rear wheel speed sensors are detecting different speeds as you would have with a setup like this? I haven't run a setup with staggered diameters since my '78 Z28 and back then it was a speedo drive gear change.

Yeah, I may be thinking of the gearing calculations being automatically done. I guess the tire size would have to be programmed for the sensors to know everything else.

So an inaccurate speedo may be the result of the difference in tire size, possibly an ABS/ESC warning light as well…unless the tire sizes are reprogrammed that is

That's the same set-up I have now. I like the wider/taller tire on the back look. No issues whatsoever with this set-up.

No loss in speedo accuracy?

Not that I'm aware of .. I'm sure it is off a bit but not noticeable to me. I have a diablo, I think I can program it in for accuracy. I gotta look into that when I have time.

Well the sidewall height difference is basically 15.5 mm, or 1.6 cm, which is a hair over a half of an inch. According to my back of the napkin math, that difference is approximately 2% (2.13 to be exact), which is within the margin of error as far as I know for the speedometer to be off without throwing a code or warning light.

What size width wheels are you using?

You can get by with 9-inch wheels for the 275 tires, but the 295 needs a 10-11.5 inch wheel for the tire to wear and perform properly.
