Amongst the three choices, i'd go with the Michelin Latitudes. You can also consider the Goodyear Wrangler and Yokohoma Geolandar.

What's the stock size of your Sportage? What's indicated on the tire pressure label on the body (it's near the driver's door frame usually)? On our CRDi 2009 Tucson, we're using 235's (which is the OEM size as well).

Also, please, don't write in text speak. ;)
