For those Rockies testing pictures, I can't make out the detail in my pictures too well but they almost look like they read as P255/40/18s in the front on special rims (never seen on a Viper before and are almost all enclosed in the design, probably to keep out the snow and ice from building up in the front rims and knocking it all out of balance) and P295/40/18s on the rear. This seems to make sense as the overall diameters are the same as a factory 18"/19" set-up, yet the road patch footprint is reduced significantly which is what you want in a winter tire like this. Factory Copperheads are 19" on the rear so it almost looks like they took the front Copperhead rim and put it on the rear or something. They are tucked into the body a ways. In the end, you are not winning any beauty contests with that set-up but if you are that desperate to drive in the cold, ice and snow, it can be done.
Again an old Jeep winter ****** starts to look pretty good after a while or you could just have a custom winter rim set put together with your snow/ice tires and then it will look okay for the winter in mild driving. I did that with my old 07' Jeep SRT8 I had. Thing was a disaster in the snow and ice so I had a custom set of Boyd Coddington Dictators in 18" with the insides dished out to clear the brakes. With Blizzacks they made the truck 100s better in the snow but that useless traction control system in that POS just made driving in snow and ice a real pain. I agree with the others here, I would not go with wider than 295s in the back.
Just because you can does not always mean you should. That is up to you, I guess. After spending the money I did on the winter rims for that POS 07 SRT8 Jeep, I should have re-evaluated how I used it as a daily driver and just gone to something else which I eventually went to a Cayenne Turbo S and have never had a problem since, neither in snow, ice, rain, mud, etc., etc. Daily driver considerations are different than weekend toy considerations as the weekend thing, you can put up and compromise a lot more. Not sure it helped but that is what I could determine from my blurry pictures while snowing last year.
