I have around 9k on my red letter General Grabbers in 31x10.5R15 on steel wheels - my first reaction to the setup aside from the asthetics which I love is I almost herniated my back lifting them out of the back of my jeep. Other than the effect of the additional weight at take off and stopping I have very little negative to stay about the tires. Transmission temps after about 3 constant miles in powder sand in 4-Lo at 15mph in 2nd gear did go above what i prefer but dropping to 1st gear and slowing down to around 7-9 for a few minutes cools it right back off without the trans going out of the acceptable range or even getting close to having a heat problem. Only reason I mention it is because it is the first set of tires I've had that did show any significant change in transmission temps under my typical beach driving conditions - I'm sure it's the additional weight of the tire versus the MT's and other tires I've used.
Drove about 80 miles in torrential rain and flooded roads and I'd give the tires an 10 of 10 for substantially wet roads and an 8 of 10 on wet roads without potential for large puddles (just topically wet) - experienced no instability, no drifting, no pulling, no hydroplaning even when hitting large patches and runs of water several inches deep - the standard wet road traction actually surprised me considering the tires arent sipped
In deep mud, they clean out great and seem to have more than adequate sidebite as well as forward and rearward traction and bite really well in everything from the thick soupy deep stuff to sandy peatmarsh mud and wet normal dirt/grass - on hard wet red clay(uwharrie type) they showed no signs of gumming up and showed very little sign of slippage on steep inclines/declines or offcamber areas - they werent far behind the performance of a dedicated mudder
These things love baby powder sand - even without being aired down they left imprints of clear unbuckled / unshifted pattern - aired down, even better 10 of 10 I wouldn't change a thing
Road noise - this is the part that I've really been happy about - for an offroad tire, 10 of 10, if they were street tires I'd give them a 6 of 10 - with the windows up, ac on and radio up to a level you could talk on a cell phone over without yelling, you can't hear them - they do have a pronounced growl but it's very low pitched - not the redneck mating call you expect from mudders - just after rotations they get louder and then quiet back down after about 200 miles
Dry / normal road manners - no swaying - low noise, good wear - handle extremely well to emergency manuvers - they do and will cause increased brake wear - higher trans temps and longer braking distances as well as lower fuel milage if you aren't already bottomed out - I can't seem to get any worse milage than i already get, it seems to be locked in to 15 city 18 hwy
Wear - these tires seem to wear very slowly - i haven't seen any signs of cupping, or abnormal leading edge wear - i see typical edge rounding on the outside of the front tires which after the first 3k had not yet worn the o dot's surrounding where the nubs were on the tires - the set i got did need a good bit of weight, but did balance out fine - have noticed no vibration
Haven't had them on any rock other than occasional exposed bedrock
