I called michelin about tire for my 1999 3500 they told me to use AGILIS CROSSCLIMATE I ask them about the. XPS RIB and they said that would be ok also any body got experience with either one of them. Trying to get a straight answer from tire dealers and the mana factory should not be this hard. They act like they do not really know. Thanks

XPS Rib is an all steel tire, great if you're running at or over max weights. XPS Rib and Defender tires are highway / all season tires. Downside to Rib is the ride is noticeably rougher than a standard steel / fabric construction tire. I've never heard of the AGILIS CROSSCLIMATE, but it sounds like it's more of an aggressive tread for off road or slick conditions?
