I am going to be starting to be making my own oil changes on my 2004 Dodge Intrepid and want to also on my 2007 Hummer H3. I bought a set of the 12,000 GVW pound Rhino Ramps. I bought the heavier ones thinking I could use it for the H3 as well. The tire limit for the ramps is 9.5 inches wide. Am i pushing my luck using them on the H3's Goodyear Wranglers?

Thanks.

Joe
