Bauer Hockey Skates Sizing

Roller Hockey HELP!!!!?
ok, i have Nike Bauer 40-70 Roller Hockey Skates. I bought them about a year ago and now some of the wheels are really bad. The only bad ones are the two front ones.
I was wondering if it is possible for me only to change the front ones without problems?
I really dont know the size of the front two wheels.
And i also need to know where to get them and how much they are..im trying to spend like $5 a wheel.
Thanks,all answers will be helpfull
