With the snowflake symbol, I am hoping to report on the suggested 15% improvement in snow and ice performance, even though I wish this type weather to stay away - I hate the stuff ! :) They are definitely better in the wet than the old AT. Done 3000 Summer miles, (would have been double if not for Covid-19), with no issues and no measurable wear on the stock 9mm tread depth. While practicality is more important to me over appearance, these tyres do look the part on my truck. Now with over 236,000 miles on the clock, my waggon is fitted with it's first set of Grabber AT3. Impressive, considering they were a lot cheaper than my previous brands. I fitted two sets of these which both lasted 48,000 miles to 1.6mm limit markers over 4 years per set. ![]() Performance in snow was only slightly improved over previous tyres. I then changed to those stylised tread pattern Grabber AT tyres, and did not notice any change in MPG as some suggested, while wet grip on asphalt was not quite as keen as previous tyres, but acceptable. These all performed ok in our UK annual weather cycles, but did lack snow and ice performance, which was problem for accessing my hillside pony field with the back full of feed, on those rare occasions. All gave about 35,000 miles to the 1.6mm UK safety limit markers, over 3 years per set. ![]() Factory fitted with Pirelli 60:40 on:off road tyres, followed by my fitting 3 sets of Michelin 4x4 Synchrone 60:40s. Purchased my P38 2.5 DSE new in May 2000. (and no, I am not being paid to say that.) Traditionally I swap tyres winter to summer (off road tyres used to be a pain in summer, and I have a second set of rims.) but I have stopped bothering with summers since the last set wore out - with these there seems no point. Incredibly good in deep snow (remember the Beast from the East?) and sub zero temperatures - the best I have ever driven. From my experience just as good as a good road tyre. I don't drive hard enough in the dry to know much about dry handling etc., but the AT3's are excellent to drive in the wet. These were significantly more expensive and definitely no better - but they are getting old and of course tyre technology is (I hope.) continuously improving each year. Traditionally I have used Goodyear Wrangler AT's and BF Goodrich AT's (and still have a set on an Jeep CJ7 that I also use - it only does a couple of thousand miles a year so they refuse to wear out.). Also some green laning in Wales! As regards longevity, the 43,000 represents the highest figure I have ever got out of a set of tyres, and it is only the fronts which are now on the limit. Numerically most miles generally round town and motorway, but frequent/significant grass, mud and gravel, plus hundreds of miles of snow each year (in the Alps). This tyre replaced the General GRABBER AT2. These tyres are approved for speeds of up to 150 mph and as an all-season tyre, the Grabber AT3 bears the M+S mark and the snowflake symbol to signify safe handling on snow-covered surfaces. The Grabber AT3 will be available in 44 sizes for rims between 15 and 20 inches, with an additional 20 LT and C sizes to follow in the spring of 2017. In off-road use, grip in mud and on wet grass has been improved and the tyre presents higher resistance to tread damage than its predecessor. On wet and dry surfaces, the new Grabber AT3 performs at the same high level as its predecessor, while traction on snow has been substantially improved. The balanced block geometry of the tread with low stiffness and the specially modified arrangement of the blocks in the center of the tread reduce vibration in the tyre, providing good ride comfort on the road. The third technology, known as “ComfortBalance” demonstrates the developers’ success in overcoming the conflicting interests of ride comfort on road and good off-road grip. This combination of design features boost the self-cleaning properties of the tread, permits good interlocking with loose surfaces and provides a large number of edges to deliver grip in every direction. “DuraGen”, is a rubber compound that provides excellent rip resistance and improves mileage in rough terrain. The technologies consist of “TracGen”, which includes an open shoulder design, traction ridges which the developers call “traction pockets and sipes arranged at different angles to enhance grip properties. The Grabber AT3 features three new technologies from General Tire that allow for high grip both on and off-road, enhanced acoustic performance and improved mileage.
