Last week while the car was in having new shocks installed,i was shooting the breeze with the "mech"when i noticed some cracks around the perimeter of the tire.A closer inspection reveiled a crack all the way around the one on the front drivers side.The cracks are also at every tread block and across the face of the tire.The one on the passenger front was not so bad but was still cracked.I checked the 2 spares that were on the back before the Nitto,s and these are also cracking.Has anyone else had this problem with these tires?The front tires have only 37.000Km,s on them while the spares have less than 20.000Kms.I,ll just add these are not a small line crack they are more like a deep crevase,they almost look like they will explode any time.I,m just glad i noticed them before something bad happened.
