Go to tire-rack and look at the specs for the tire and it will show all the sizes and rev. per mile on the tires. See if its the same. (compare only the rear).

The 295's are a tad taller....like around an inch. Not sure if it's enough to make a difference with your speedo. If anything your ABS might complain about it, but again, don't think the size difference would be enough. As mentioned check out their site or Tirerack for specs on the size of both tires, what you're looking for is overall tire diameter. The stock diameter is around 25.6"

the 295 is 26.1 inches tall and the 275 is 25.6 inches tall. the stock tire height is 25.6 so the rear will be a little taller. but it shouldnt be a problem at all

Guys I'm runnning 275/35/18 front and 295/35/18 rear w/o any problemw with the ABS system.

The rears will be slightly taller as mentioned above so your speedo will be slightly off. Nothing to worry about. But I did update my PCM after buying EFILive to the correct pulses per mile so my speedo is back on track. But you really don't need to do this as it doesn't affect it much.

I never recorded the difference, but when he says not much, he means it. I run the same sizes on my wheels, and I didn't really notice a difference, but corrected my speedo with HPT none-the-less.

81.954" is the circumference for the new tires , the old ones are 80.384" which is a 1.9% difference, so at 100 on the speedo, you will be actually going 101.9...not that big of a deal

275/35/18 & 295/35/18 KDW 2s are what I am going to be running as well. The .5 difference shouldn't affect the ABS or have that much affect on the speedo, less than 5MPH.
