Hey guys I was wondering if there is a better hydraulic jack out there for changing a flat tire than the bottle jack that comes with the jeep. I have a 1999 sahara (stock for now) with 30x 9.50 on 15" wheels. Also I'm getting (dedicated)winter tires this weekend and will probably get a set of blizzak dmv1, but does anyone here run the lower priced firestone winterforce and if so how are they on rain and ice? The jeep will be used mostly to commute to work on snow days, 22 miles roundtrip highway in Connecticut. Thanks in advance for your replies . Oh one more question, what is the equivalent tire size for the 30x9.50.
