I made the switch to 285/55/20’s Yokohama G015 AT from Michelin Lat. Tour 285/50/20. No issues with fit on stock rims on an 08 LX. Noticeable drop in mpg’s but worth it for my needs. I thought long and hard about switching to 17” or 18” rims but I prefer the look of the 20” rim on a truck of this size.Ok so I have read this thread twice and for stock 20 inch wheels with no modification at all, 285/55/20s fit with no chance of any rub anywhere but 275/60/20s have a good chance of clearing with no trimming but might need a little heating and massaging of the fender liners. Wider tires start contacting the control arms which require spacers or wheel offset change which in turn causes more fender liner problems. Going to the Tundra 18s gain some ride quality but will require spacers because of the offset difference. Landcruiser 18s have the same offset but are harder to find. Aftermarket 17s seem to be ideal with a 285/70/17 provided you get the right offset. Does that about sum it all up?
Thanks
