Larger Wheels...Smaller Wheels

I've spent some time researching wheels. (At first it was to help determine what kind or size of wheel to get for a new set of snow tires, but it's gradually become an all-encompassing vortex of time consumption for me..) That said, I'm sure I'm still woefully ignorant of some of the finer details.

What I'm curious on is the appeal of larger wheels on modern car designs. Older cars generally had anywhere from 13 to 15 inch wheels, today that average has expanded anywhere from 16 to 20 inches or more. From what I've read on the topic, larger wheels offer somewhat of a handling advantage due to the more narrow sidewalls. But that comes with a trade off in additional weight and fragility as the smaller sidewalls are less resilient, along with having less tire material to cushion shocks to the wheel itself.

Is the appeal mostly aesthetic, or is there a practical reason behind up-sizing that I'm missing? With actual off road usage as far as the Cherokee itself goes, I would think that larger wheels would offer more of a disadvantage, but I can't seem to go a day without running into another thread on larger wheels or tires. Just speaking for myself, I can see the appeal of larger wheels and narrow sidewalls on a road-hugging sports car, to an extent, but outside of that narrow field, I'm left scratching my head on their rampant popularity.

LOL. Yes its all about "the look" and you do gain a little handling with that which is more meaningfull on a sports car but on an suv mostly the look. The larger rims cost more, bend easier, are harder to balance, ride rougher, tires pinch and damage easier and are worse off road. All for the look lol. I never bent a single rim in 30 years of driving but bent two (at $700 each) on these 20s in one year. To me they are fine and I would not get rid of them but they can be a pain, balance needs to be perfect on them or they will shake.

Re: Larger Wheels...Smaller Wheels

The other reason for larger rims these days is larger brakes. Smaller than 17in will no longer fit.

Re: Larger Wheels...Smaller Wheels

Basically two points here:
#1. Your snow tires need to be the same size as your existing tires. That is if you have 17" tires you need to get 17" snow or AT type tires. Its the total tire with rim that's say 17". Also its all 4 wheels which can get expensive.
Also you need to consider any total size change of tires will require the dealer to recalibrate your speedometer. 2 changes a year would require 2 recalibrations at the dealer.
Since you have AD2 why not consider running AT tires on your chrome rims year round and not worry about changing them out for the winter.
That Latitude will look great wearing those AT's. I had them on all my prior Jeeps except this Limited.
The Continentals on my Limited do great in the snow when in 4WD. The AT's would do better especially up in Canada with the longer winters and more snow.

#2 The appeal of larger wheels in my opinion has to do with the simple fact of physics.
The larger diameter the less RPMs have to be used. That produces longer engine life. Less RPMs produce a bit more MPG. That is coupled to the understanding that the engine requires a bit more power to drive those bigger tires/wheels. But at highway speed they shine.
Try riding a 2 bikes, each with different size tires, with you peddling.

Also as was mentioned it does allow for larger brakes, especially larger rotors with a larger cooling area. Maybe that will help with warping rotors on this Cherokee.

For off roading I would imagine that larger tires would roll over obstacles etc. a bit better.
Also a larger tire would give you a bit more road clearance which would be beneficial in almost all driving especially off road. An extra inch can at times make a huge difference in bottoming out especially in heavy snow.

I would include your dealer in your calculations as the dealer can give you a lot of insight related to your Cherokee. I am sure he can give you a competitive quote.
Good luck

First, thanks for the detailed response. I have read that downsizing the tire size for winter is more helpful (somewhat paradoxically), as the more narrow the tread, the easier time the tire has pushing snow out of the way to get to the actual road surface. The calipers on the Cherokee design apparently make that impossible without wheel spacers, and I'm not so enamored of the idea to go to all that trouble, and probably additional stress on components. AT tires were part of my consideration, but the vast majority of them seem to come in a size other then 225/65/R17, so unless I invest in new wheels I'm not likely to get those.

Since posting this originally, I've done research on some of the more modern "all-weather" tires that would be almost as good as dedicated winters that actually fit my rim size. Specifically the Nokian WRG3 and Toyo Celsius, along with a few others. Depending on just how my stock Destination LE2s handle this winter, I'll have them on my shortlist.

I agree that a larger tire would help with clearance a bit. I know the Trailhawk trim gets a bit of an extra lift from the stock tires over my own setup. As far as offroad use goes, personally I think any advantage you would get by rolling over obstacles would be mitigated by the extra fragility of the tire sidewalls, at least once you get past 18 inches. As far as fuel economy goes, I would think the extra weight would more then offset the RPM difference of only a few inches or so, but that's just my own feelings, I don't exactly have an experimental setup handy, so I concede it could go either way.

I'm planning on getting the skid plates retrofitted sometime next spring, so I'll have to get the dealer's opinion on tires while I'm there. 4 plates, 3 of them are pretty much directly bolt-on, but the 4th disassembles most of the front fascia and undercarriage, so I'd rather have them handle it if possible.

Re: Larger Wheels...Smaller Wheels

Neither All Season or AT tires are good in temperatures around freezing and below, snow tires will make a difference.

Wow. ^^^^^^^


Larger wheels wont do anything to your speedometer or engine rpms.

All of that would have to do with your tire size.

You can have 20 inch wheels and have the same tire roll out as you do with 17 inch.



All terrain tires are fine in freezing conditions, they aren't changing the rubber compound based on temperature. All terrain vs snow tires have different tread patterns and more or less siping. Not softer rubber or harder rubber.
