I think I want to avoid studded because I do a fair bit of highway driving. All signs point to KO2. From everything I’ve seen, they appear to be great tires. I was at the dealership today and the folks in the service department were quite surprised to learn that the OEM tires were without the 3peak rating. They all recommended the KO2.Hey LeviGarrett,
Nokian makes the Hakkapeliitta LT3 in LT315/70R17 (121/118Q, Studded, max load 3200 lb, speed rating up to 100 mph). This is approximately 34.4 x 12.4 inches on a 17-inch wheel. That should work on a Tremor. See: Nokian Hakka LT3.
If you are shopping for Duratracs, it sounds like you are already aware that some models of the Duratrac are rated "three-peak mountain snowflake" (3PMSF), and some are not. You'd think that 3PMSF would be consistent across different sizes or load ratings of the same model tire, but that's not the case. Maybe they sacrifice the softer/stickier rubber compound in the 3PMSF tires to increase load rating or tire-longevity (just a guess - I don't know why the snow-rating varies). Here is a short excerpt from the Tire Rack:
"Most Wrangler DuraTrac light truck tires are branded with the three-peak mountain snowflake (3PMSF) symbol to identify they meet the industry's severe snow service standards and if so, will be noted in the tire's Details & Pricing section. The absence of the "Severe Snow Service Rated" text indicates that size is not 3PMSF-branded." (Source: Duratrac page on the Tire Rack)
However, according to the Tire Rack, all BFG KO2s get the 3PMSF rating (but I'd still check before buying):
"Note: BFGoodrich All-Terrain T/A KO2 tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol." (Source: BFG KO2 page on the Tire Rack)
Next question. 4 KO2’s or 5? I beloved we have a full size OEM spare. For uniformity if I need to change a tire would I want to order 5 and would the slightly wider KO2 even fit?
