I can confirm that P285/50R20XL Blizzak DM-V1's will fit on the factory rims and do NOT rub. I got a great deal on my 2014 but it came with the 3 season rubber and the Pirelli snows were back ordered a month. No chance to wait living in MN.
I have never posted pics before but took some today to give you a close look on the fitment. Based on discount tire calculator and my pics I think the extra 1.12inch diameter may require some trimming. My 50's are a snug fit.
Hope this helps - I know I searched forums forever without getting a clear answer so I just went for it. Glad I did - love the Blizzaks.
Thank you so much much, this info is really helpful... I know the blizzaks will help me with snow, i dont know about the gravel.... I run 8 miles of gravel round trip up here in montana... And with the srt8... It is really fun to go drift around corners and fly on the straights....
I dont think i can go to a 55 based on your pics....so i will have to find a 50 that can handle the offroad.....unless someone else can confirm a 55/r20 fits
I just looked over on discount tire's site and they have some promising looking Nitto, Falken and Cooper all terrain tires in 285/50R-20. Just be aware some of those AT tires have some prominent tread bolsters that might rub on your inner wheel well liners.
Thanks you all... After 3 flat tires in the weeks.... And the short wheelbase being really squirly on my roads... I gave up the fight and traded my srt8 on a Yukon xl denali.... Much much better for my particular situation... Correct vehicle for the job... I'll miss the srt8... The denali is pretty nice too...
