The key is that all four wheels have to be the same diameter within some small amount, usually stated in your owner’s manual. You can measure this yourself in a number of ways. One easy way is with a simple wooden yardstick, two clamps, and a ruler. Clamp the clamps at right angles to the yardstick such that they’re just touching the circumference of the new tire, do the same with the opposing tire, and compare. Of course, if your other tires already have significant wear and you’ll be changing all four soon anyway, you may as well do it now.
and, as always,even if the circumferences match the new tire should match or be a very close match to the existing tires in ratings and tread. If there’s any question on this, change the tire on the opposite end of the axle to match the new one.
