As some may be aware it was almost impossible to get any sort of AT type tyre for an X-Trail running the standard 17 inch wheels.
The more recent X-Trails on 17 inch wheels have been fitted with either 215 or 225 width tyres, the 225 width tyres will fit cars that came from the factory with 215 width tyres and, in fact, 225 is now the standard from the fectory.
Now that it is time for me to change tyres again I've noticed that there has been a considerable increase in the selection of AT tyres available to X-Trail owners. I currently have 225/60 Yokohama Geolander AT/S tyres on mine and have a new set on the way but I've noticed that General Grabber ATs, Falken AT01s and a few others, depending on what it takes your fancy to search for, are now readily available in the UK.
I know that there are quite a few on here who use the X-Trail and the only really big negative, for me anyhow, was the tyre situation but it would appear that this has now been resolved.
If you are running your X-Trail on the standard fit Dunlops or other road tyre it is worth considering fitting an AT type tyre - the Yokohamas that I've been running for that last 2 years have no disadvantages over the Dunlops that I can see apart from a slight decrease in MPG but they perform much better off road and in the snow. I'd say the Yokos are at the "softer" end of the AT tyre range and if you go to a more serious AT pattern then you might experience some decrease in on road performance but it is well worth giving the matter some consideration.
