That is not a real tire shop like said above they are a car shop, Any real truck tire shop does em and fast too, they are not the most dangerous split rims ever made, they are only dangerous when filling them up, any truck tire place that does big rig road calls does em, like said above there are alot out there still on the road, Service tire in Budd lk NJ, charges 20 bucks to pull one off and put one on, plus 20 for a new tube if u want one,Watching these guys is awesome, any of them do a off and on to air in like 3 to 5 minutes each , they pull the air valve insert, pop the trim ring in about 10 seconds, pull the tube out put it on the spreader ,put the tube in and slide on rim,then puttrim ring on and in the air up saftry frame in like 3 to 5 minutes a tire , I always tip em good they are awesome, they say they are easy, oh and they will do it at my shop if i want for the same price, if they do it there are a thousand others who do it too.
