Thats just one of the reasons to buy them..along with the quality of the workmanship,fit and finish,and they STILL look nice after 3 seasons of use,and the fact i DON'T have to worry about potholes or smashing them,like you do with cheaper ones,that is unless you jack up your torsion bars so the cheap ones clear everything,i find most people that say negative things about tti's are the ones that don't run them,people who have them usual love them...like an old saying goes.."quality cost how much you want to spend"...
