285-50-22 will have less than 1/4" more sidewall than 305-45-22. Not worth worrying about. Get the extra tread/traction or go to 20s for more sidewall.FL_Crushin said:Does any tire maker have a 285/50/22. I want the 22's but would prefer just a bit more tire on them. I haven't had any luck finding any. Will probably just have to go with the 305/45/22's.
