Tire size questions

I have a 2015 Cherokee Trailhawk. In preparation for winter I have started looking into available winter tires and unexpectedly ran into some curious problems.

The first problem is that because the trailhawk is designed to some degree as an off road capable vehicle and has some great traction capabilities, I want to keep the tires "all terrain" both for aesthetics and to retain the off-roadability. The destination a/t tires that ship with it, combined with the traction capabilities of the trailhawk will do just fine in snow but here in Calgary, Canada we get icy roads and ice traction is a different story. Tires require lots of siping and soft rubber to be useful. So the first problem I had was finding an A/T tire with lots of siping (the thin squiggly cuts) which is not easy. Trying to find ones that aren't directional (so I can rotate the tires easily) is even harder. I did find a couple. The goodyear wrangler duratrac, and the cooper discover a/tw. (Google image search those for pictures). This promptly brought me to problem #2...

Neither of these tires are available in the size stated for the trailhawk of 245/65/17 despite the fact that this size would appear to fall squarely in the middle of the "range of sizes" available for these tires. I can only assume that for some reason 245/65/17 is a weirdly uncommon size. Looking at the manual it says that snow chains are permitted on the trailhawk if the tire size is 225/65/17 tires(17x7.5 wheels) so presumably that size would work but the tires aren't available in that size either.

So with arms flung in surrender I turn to the owners and others on this forum for some help. Obviously the tolerences on the trailhawk wheelwell are tight or I could put chains on the 245's (which I can't) so I need to be careful. Can anyone here point to either a good A/T tire that has winter siping AND is available in the 245/65/17 or point to a size that is more available in either of the two tires I mentioned that will work without issue in the Trailhawk?

Re: Tire size questions

Here are some real winter tire choices in the OEM 245/65-17 size:

***Studded Nokian Hakkapeliitta 8 SUV;

Nokian Hakkapeliitta 8 SUV - Nokian Hakkapeliitta 8 SUV studded tire provides grip and durability like never before / Nokian Tires

***Non studded Nokiian Hakkapeliitta R2 SUV;

Nokian Hakkapeliitta R2 SUV - The most advanced non-studded winter tire technology for drivers of SUVs / Nokian Tires

***Nokian WRG3 SUV All weather Hwy tires w/severe ice/snow rating;
(These can be used all year round)

Nokian WRG3 SUV - Nokian Tyres is introducing the rugged, high-performance Nokian WRG3 SUV all-weather tire for varied use on sports utility vehicles. / Nokian Tires

***Nokian Rotiiva AT All Terrain All Season on/off road tire with severe ice/snow rating;
(These can also be used year round, are not directional and best fit your posted requirements!)

Nokian Rotiiva AT - The best all season tires for northern conditions / Nokian Tires

Notice all of these choices are Nokian tires....... Nokian invented winter tires in the 1930's and hold more winter tire patents then all the other tire companies combined. They are the absolute best when it comes to winter tire traction & technology!

I appreciate the suggestions, however the ultra grip is a directional tire, the wrangler and fortera are not suitable for off road. If you look at the pictures of the two I mentioned you'll see the "look" I'm after. It needs to be "all terrain" AND winter rated.

The Goodyear Wrangler All Terrain were what was recommended to me for both offroad and winter driving. Unfortunately for me they don't make them in the Latitude stock wheel size, so I'm considering Nokian WRG3's. They do fit the stock Trailhawk wheels, however. They have the severe snow condition symbol.

Re: Tire size questions

Nokian also has the world ice speed record--about twice what a Cherokee will do.

Why worry about off road capability? Are you planning to go offroad as well as need to worry about avoiding accidents on ice?

Re: Tire size questions

I managed to find a tire that worked! I bought the Dunlop Grandtrek SJ6 tires. They came in the correct size (245/65/17) and seem to rank quite well as an ice/snow tire and are also all-terrain.

thanks for all the help folks.

Now I need to find rims. The black rims that came with the car are $600/pc which is crazy so I need to find some other ones. Thing is, different wheels have different "offset" numbers. Any idea where to find what the offset is for the wheels that come stock on the trailhawk?

When the cars are all piled up on the road I want to be able to hop the curb and drive around them in the ditch. :-)

Re: Tire size questions

Stock rims are 31mm offset.

I will never need chains so am fitting the Duratracs this week (live in subtropical area). Apparently there are some (expensive) 6mm wire 'chains' that might fit.
