245/75R17 - anyone using them?

245/75R17

I've heard conflicting reviews... will I be able to fit on a Commander Limited 4x4 with stock suspension; no lift kit or spacers?

I'm looking at snow tires.

Please let me know if you know!

Thanks!

Note the dimension specs on tires are Theoretical (or rounded off to the closest standard size), i.e. the actual dimensions vary a bit between brands/models.

Likely that is why the listing for tire sizes that fit, for the one size that just barely fits, 245/75R17 also lists the Brand/Model that was tested. Other brand/models of tires might be a tiny bit smaller or bigger than the one tested and you would get less or more rubbing issues than the one tested.

Remember the width is actually the tire width at its widest point (somewhere down the sidewall), NOT the width of the tread, so two tires of the exact same "listed" size can have different width treads. As well, the tread patterns can have different shoulders, one more rounded off on the corners and another more square and be less or more likely to rub. Even the diameter can vary a bit between brands/models and still be listed as the same size.

You can look at the specs at some of the online tire sellers, compare your tire to the brand/model in the list above, see if you can tell if your tire is slightly bigger or smaller. Look at pictures of the treads and the shoulders of the tread, judge if the shoulder is more likely to rub than the tested brand/model.

What brand/model? Like I said the actual dimensions vary a tiny bit between brands/models.

So, the brands/models you have in that size fit without any rubbing. Have you had the tires since they were brand new?

According to quoted list, at least some of those that have BFG AT's in 245/75/R17 have experienced minor rubbing issues.

Yes i have this size since i purchased my jeep. I had even the 235/75 r 17.

I have a 2007 commander EU version.

At the time i don't remember the brand of my snow tires but i ll check it for you as soon as i gonna install them on my jeep.

In past i had the Pirelli Skorpion as snow version, but are not pure winter tires cause are all seasons M+S.

The one im using now are really performing great on the snow!!

BTW i ve never had any issues with this size, i have also a 2" lift kit installed on my jeep.

Did your 245/75/17 snow tires fit without the 2" lift?

I have no lift kit and do not want to use spacers...
Thanks!

245/75R17 BFGoodrich All Terrians (might have minor rubbing)
That was for a stock Commander, NOT lifted.

To me, minor rubbing means an annoyance, NOT damage, likely this tire "might" rub when you turn the steering wheel all the way to lock, and then it will only be some noise and vibration. Maybe rub some paint off the frame rail, round down the edge of the shoulder of the tread a tiny bit.

Like I said, do a little internet research, go to the manufacturer's web site or a big tire seller's web site, look up the specs for the 245/75R17 BFGoodrich All Terrian and the specs for your tires and compare them.

If the dimensions are the same, its reasonable to expect the results will be the same as the 245/75R17 BFGoodrich All Terrian, if they are smaller, good chance there will NOT be any rubbing, if they are larger, good chance the rubbing will be worse.

Remember the big one's too look at, "Overall Tire Diameter", and if common sense didn't tell you this, the "Rev's per Mile" is another good indicator, the tire with the higher rev's per mile, should be smaller in diameter. Just as important is "Tread Width", that is how wide the tire will be at the point it rubs, the dimension in the listed its size is the widest part of the tire, somewhere on the sidewall, NOT how wide it is at the tread. Finally compare the pictures of the tread, there are NOT many tires with a sqaured off tread shoulder like the BFG AT's, likely you're tire is more rounded at the shoulder (i.e. the actual point that will contact the frame rail).

Why the same tire might rub on some Commander's but NOT others? There will be variances in the contruction of the vehicle and its body, slight differences in alignment from Commander to Commander (and the difference may be for the variance in the body). Notice how everything in life has a +/- to it. So, a tire that just barely clears with 1/32nd of inch on one Commander, could very well rub on another Commander, simply because of the +/- in the vehicle and its alignment.
