Had these for just over 2 years and 20,000 miles and they are just on the verge of needing replacing.
I waited this long before doing a review so i'd have lots of genuine information.

Good points:
Snow/Ice = Excellent. I have run them on 3 trips to the Alps with up to a foot of snow and they have been predicable, lots of traction and very sure footed.
Tough = sidewalls have had a fair number of scrapes with granite rocks and they are still perfect.
Mud= surprisingly capable, self clear quite well considering. For instance just spent an afternoon pulling horse boxes out of a show in horrible claggy mud and slippery wet grass. Not as controllable as a KO2 but they kept going....but you could tell they were at their limit.

Bad points:
Noise = started off well, but after about 5K miles, they started to have a solid persistent hum. This is in a premium 4x4 with really good sound insulation, imagine in a pickup etc it would be really bad. They have got steadily worse with age.
Wet grip = terrible, cornering at normal road speeds I have had the traction control coming on way too frequently. I do not have confidence driving these in the rain anymore on the motorway.
Fuel = terrible also, they are noticeably worse than the grabber AT3's I had before.

Summary. They seem to excel in the tougher conditions. Sadly that makes them sort of pointless for me as with their poor road manners and high fuel consumption you might as well just go for a more aggressive AT where i'd be sure they'd work when the going gets really tough. Conversely, If I needed ice and snow and road manners I'd go for a good all season SUV tyre and save a load on fuel and be nice and quiet.

Had the TrailTerrain fitted for a few months now and all I can say is wow. Excellent comfort, no noise compared to my normal tires, and while I've not tried them in ice yet in the snow they felt better than my all seasons. Highly recommended.

1st) there is the looks. These tyres looks amazing! You cannot get around that (Silver 2021 RAV4 Hybrid with white letters showing)
2nd) I was impressed with the road noise, or lack thereof. For an AT, these are very quiet.
3rd)tread life looks good. I am currently at 78000km on them and still have 4.5mm left all round. I did not baby them, but mostly do high way driving on tar.
4th) Who ever said in a review that I red when I got them ( there was very little to no reviews as they were brand new) that "they do not increase fuel consumption " was full of ......
Why do I say that? Because there is no reference point as to what the person used before. Did they run KO2's? Then of course there will be no increase in consumption. So my reference is the OEM Bridgestone Alanza HP. Compared the that, I lost 1-1.5km/l with the BF's. Its understandable. Its heavy and it is an AT. I am running 225/65R17 and my current average is 16-16.5km/l
My next set will be high way summer tires again, then I can easily be in the 17's.
5th) The wet grip is BAD. Like really bad! At robots in the rain, touch the throttle to hard and its spinning for days ( I have an 2x4 hybrid)
I once overtook a truck in the wet, and at 60km/l, my car started spinning its wheels. I know the stretch of road very well, so I can confirm that my Bridgestones never did that.

Will I buy again? Probably not. We have no snow, hot climate. Fuel consumption and wet grip is the downfall. We have super bad roads here, but I can cope with an HP tire.
For the looks yes,they rock, but sadly not again for me.

Greetings all the way from South Africa

Review your BFGoodrich Trail Terrain TA >

I have been driving them for 4 month in dry conditions and done a fair amount of offroading mainly on gtavel and rocky terrain. While they handle very good they are outragiously noisy when on paved tarmac. I jave previously driven on some other tires on offroaders, such as the pireli scorpion which tobmy opinion can noy be called at tires as they are very volunrable, and toyou open country which i didnt like at all, , and cooper discoverer at3. On my current rig a 2009 pajero diesel, i had toyo open country when i bought it an was happy to replace them and was tempted to go for these bfs afyer having a great experince with bf km3 on a previous rig. Unfortunatly, these are the lodrst tires i have ever driven except for yhe km3s. On any givdn day i would take cooper at3, whicj ate far more quite and very capable off road. Sorry, but while the trail terrain ticks msny noxes they are way too loud. I wont buy thesr again.
