Chains on 2015 Cherokee with auto 4WD?

Does anyone know if you can put chains on with the new auto 4WD? We live/travel in areas that sometimes require chains even with 4WD.

The owners manual will tell you what is allowed and what type of chain you must use.

Even those fancy ones can cause a lot of damage if you let them get worn.

? What area requires chains on a 4wd with snowflake snow tires?
Don't know of any in the USofA--not to say there isn't.

Snow Chains and Yosemite National Park

Conditions dictate when chains are required at Yosemite, which makes it hard to know when you'll need them. The Yosemite website strongly recommends having chains with you from November through March, but they could be needed as early as September or as late as May.
Park regulations require that you MUST carry chains when driving in designated chain control areas, marked by a sign that says, "CHAINS REQUIRED" - even if you are driving a four-wheel-drive vehicle.

Many places in the US require them.

Chains shouldnt hurt the 4x4 system of any jeep unless you try to just run them on front only or back only.

Re: Chains on 2015 Cherokee with auto 4WD?

Chains are only a traction aid and if used on all 4 tires and are appropriate type as to not hit the body of the vehicle and not interfere with the brake hoses and antiloc wires on the car when turning the wheels they can not hurt your vehicle!
If they are used on front or rear only they can change axle ratio and mess up transfercase or differentials. it could also confuse anti loc brake system if only used on one end. I would prefer to use 4x4 without chains but they used properly and kept tight will not hurt 4x4 system or transmission, unless spun on dry road or excessive speed used.
I recieved this information over the 25 years that i have been an ASE Certified
Master Mechanic and living in the Mountains of North Carolina. I have helped install chains on more than one 50+ thousand dollar suvs during snow events!!

Re: Chains on 2015 Cherokee with auto 4WD?

Pages 509 to 511 of the online PDF Manual state the following:
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body clearance. Follow these recommendations to guard against damage.

Four Wheel Drive (4WD) Trailhawk Models:
The use of 9mm snow chains is permitted with the use of 225/65R17 tires on size 17 x 7.5 ET31 wheels.
CAUTION!
Damage to Four Wheel Drive (4WD) Trailhawk Models may result if tire chain or traction devices are used with original equipment tires.
So for reference you should have OEM 245/65R17 tires on your TH. They are recommending that you cut down on the width of the tire by 20mm to allow for a 9mm diameter snow chain and still have 11mm of room to spare to maintain normal factory spec clearances.
So this of course all depends on the type of snow chain/cable you intend to use. There are other posts out there on manufacturers, however I looked at Thule and there are others too that are designed to not install on the interior sidewall of the tire and therefore you avoid the whole clearance issue from the get-go. Fair warning as they are a bit pricey.

Think of it this way, put bigger or wider tires on your car and you may have some rubbing or noise when you turn the wheel full deflection. Now think about how chains would rub on your wheelwells. NOT TOO GOOD!!! Don't turn your wheels fully and you're okay regardless.

Re: Chains on 2015 Cherokee with auto 4WD?

I saw on some other places where people are using chains on front or rear only. i would still use them on all 4 wheels to keep the auto 4x4 from thinking the wheels were spinning because of the size difference of the tires with chains vs the ones without. make sure you have clearance and keep them tight!! will be fine!!

Re: Chains on 2015 Cherokee with auto 4WD?

If you use them, put them on all the wheels and drive slowly for best results. This should be common sense if you have driven in chain up areas. I hated putting them on, but occasionally, decades ago approaching Truckee or some ski resorts in the Rockies that had poor roads, pre 2002 Olympics, where the roads were massively upgraded, you were wise to have them, but rarely mandatory up to Snow Basin or Powder Mountain resorts. Getting to Steamboat Springs during heavy snows that made the canyon area above Boulder pretty treacherous, but I never had to ski, that bad. My BIL did some times and he also hated chaining up but did several times. Slow going and pulling them ASAP never caused any issues on his vehicles.

Plenty of good information above as well.
