You are looking for a 255/70r22.5 right? I have been having very good luck with the Sumitomos. They are a little softer tire, which will ride better. Best of all, these tires are not out of round as bad as most commercial tires. This will create a good balance without having to shave them. Any local big rig tire dealer should be able to get them. Also for an online link, www.duallywheels4u.com
has the 908 series for a good price. Mario is a super nice guy to deal with too.
