Tire quesion for XJ Sport 2WD. 225-75-15 or 215-75-15 or does it matter?

I need 4 new tires for my daily driver XJ Sport 2WD. I bought it with 215-75-15's on them, but when I search for tires online they I always get the result 225-75-15. So have I been driving on the wrong size tires? Do those 5mm really matter? I found some of the 215's for the cheapest so I would like to stick with those.

When I search for tires on sears.com I get different sizes for different trim levels.

SE : 215-75-15, or 225-75-15
sport : 225-75-15
sport police: 225-70-15
Classic: 225-70-16
Limited: 225-70-16

I thought the only differences between these had to do with stuff like power windows, so why different tire sizes.

Not a clue why they list different sizes for different trim levels. From a fitment standpoint, a 225-75 will certainly fit, with no problems. I'm currently running 225-75's on my '94 sport, and ran the same size on the '87 Pioneer I used to have, and have never had a problem with either. One thing to keep in mind is that changing tire size will affect your speedometer accuracy. My '94 Sport had 205-75's on it, IIRC, when I got it, and the speedo was off. Changing to 225-75's put it dead-on accurate. A 215-75 is 27.7 inches in diameter, while a 225-75 is 28.3 inches in diameter, a difference of only 0.6 inches.

You can check the door plate to see what it left the factory with.
Mine came with 235's and my speedo was within 1 mph at highway speed.

If you can find a 215 in a make/model you want, then buy it.
If not, then get either 225's or 235's. Anything bigger will start to be a problem...

235/75-15s work good and are fairly cheap
