Officially no, Toyota does not recommend use of any chains (standard link or low profile cable) on the front. That's in the owners manual. You may or may not have luck if you try. I wouldn't risk it unless I was going slow and straight.I cannot seem to get a definitive answer on the tire chain/cable use on the 200. I have a LX570 with stock 285/50-20 Yokohama Geolander A/T G015 with severe snow service rating (3PMSF). Since I live in Texas, I've only had great experience with snow and bad weather traction with this tire when I venture out to ski or off-road on occasions. I also carry a set of 4 (front and rear) of the peerless/SCC Z-type chains that are rated for Class S-Clearance.
Back to the original questions:
1. Does Chains fit the FRONT of the standard 200 series for both Landcruiser and LX570 OEM wheel and tire sizes?
2. Does the low profile type of traction aiding devices like the class S cable/chain clear the front of the 200 series?
Now back to your regular programming
