Probably...................

The width difference between the two is minimal. But from the calculations below the rotations per mile is off a bit.

285 is tire 1 and 295 is tire 2

Speaking of AVS Sports, WHY does Yokohama not make this tire in a 285/30-18 is beyond me.

they just recommend that it be within 3% of the original tire diameter bigger or smaller. any more is not recommended, and the fit your asking is below 1%, so your good.
