Ditto what everyone else said......I'm not really sure what they designed the Thornturd for. They look retarded, ride like hell, don't balance worth a shit, are kinda expensive AND don't do well on the road or off.
I drove a customers Wrangler with some half worn shitbirds on it and it nearly rattled my fillings out. How she could stand being in there everyday I'll never know, as it was without a doubt the worst tire I've ever had the displeasure of driving on!
I went on a trail ride with someone who was running thronbirds....He was getting stuck everywhere when others were not. He had to be winched on some of the easiest stuff, just could not find traction.
