I have a practically new set of Blizzak, 255/50R20 tires that I want to put on for the Winter, to replace the 245/50R20 seasonal tires. The Blizzaks have only about 4,000 miles on them. The difference in diameter is only .49" and .5" in width. Is this feasible? Seems like the difference is not enough to cause rubbing anywhere. Any feedback is appreciated. Thanks.
