Well thanks guys. I grooved my TSL's and have not got to try them in the snow yet. I did a lot of damage at our local top truck challenge last year and missed the snow season. I finally got my 42' IROKs and was just wondering if I should groove them as well. I have them in my garage unmounted and they are WAY softer then the TSL's, So I guess I will just run em.
i would run them first. Iroks are killer in the snow without grooving
