Hi folks this is my first post here, I've done a search on this but did'nt find a answer. I have a 02 chevy 2500 hd with the allison trans. i have read not to go to bigger tires, but i can't find anyone that has actually done it and had problems with the allison. has anyone here tried it ? by the way this seems like a great forum. thanks for any help you can give me.
