The 27 executioners are big, heavy for a low boor machine but they are great for mudding do to the tread death and the width of the tire that keeps you on top of the mud better than the skinny execution like the stock 25's that are skinny and dig down into the mid, they skinny are good if there is a bottom. Both are good but in my opinion the 27 are better, I would highly recommend these tire for trail/ mid rider. These tires wear like iron and last a long time, the are also one tough tire, they are extremely hard to puncture and they have the biggest rim guard ever, the 25's have a bigger one than the 27's. I rode my executioners at welsvile and that place is basically all razor sharp for and I did not have a single puncture, will the other rider I rode with the rock slashed right through there tire. You just can't beat the price of these tires.
