The tires were all on a 2007 toyota FJ cruiser. I went in oder on the tires.
Every tire i ordered had the Kedge grip option wich is either crystals or almond shells mixed with the tire compound. As you drive the shells pieces fall out and give you tiny holes in the rubber adding to the gripping power.
This is with the last set of tires. The all terrain. I deff used the tires to their fullest.
Agressive mud terrain.
These lasted the shortest amount of time. But did GREAT in mud and offroad.
Less agressive mud terrain
These lasted longer, did good in mud and offroad byt not as good as the aggressive mud.
These by far lasted the longest. Did ok in mud, great on gravel roads.
I only had one issue with the tires. The first set i got of the mud terrains one of the tires developed a bubble in the tread. I called treadwright and sent them email with pics. I was getting pretty close to ordering my next set and in that set one of the tires was free. They stand by their product and unless you puncture it yourself or mess the tire up yourself. As far as i understand it they will replace the tire if it goes bad.
