Can 265/65R18 tires can replace stock 265/60R20?

Self-confessed newb who has tried to use a few calculators out there but still would prefer confirmation from more knowledgeable folks. Just wondering if I can use 265/65R18 winter tires / rims in place of the stock 265/60R20. I have the former from my GMC Canyon and if I can avoid having to buy new tires and rims, would be nice.

 

Sure, you will need to use 18inch rims of course. Rims need to be hub centric and fit the tundra bore and bolt pattern. Not sure if GMC wheels will work on a Tundra, nor do I know the GMC wheel offset which may or may not present a problem.

 

Ya, just confirmed the bore and offset are not compatible. So will need rims. Sigh. Ah well. Thanks!!
