Dean Tires Wildcat EXT

i brought a set of 5 about 4.5yrsago and unbelievably i have not had no punctures yet as ive still got one brand new one left.i go all over wales on offroad events 3 to 4 times a year plus i use it most days,in my opinion these tyres are 100pc,never let down at all.i normally run them at 15to20 psi when offroad,they are 34,. reccomended,no problems................
