Khumo has been my tyre of choice over BFG, but , being a Yorkshire man, price may have helped there!The ones I have had where the early BFG copy so no difference in pattern, nice flexible tyre, never had sidewall issues. Later BFG have better edge/side lug cut may be some advantage there. Kl 78,s never look like a deep tread to me, but thats just an opinion/observation.Realy useful link here for comparisons; http://www.offroaders.com/tech/AT-MT-Tires/index.html
