Hi! I'm new to the forum. I just gave my niece my 1994 Toyota Camry (which still runs like a dream) because she's going to Brigham Young University this January. So, I'm in the market for a new vehicle. I've been researching for two years. I talked to my niece's husband-to-be last week and he told me he drives a Mazda 3. He loves it but wouldn't recommend it for long road trips (which I plan to do this spring). Mazda had never even occurred to me; everyone in my family either drives Camrys or Dodge Rams. Then I started looking at the Mazda 6 and the Mazda 6 Grand Touring and suddenly, everything seemed right with the world! I knew this was "The One," (and I freely admit, I am not a "car person.") However, how would this vehicle do in desert heat or/and on poorly-maintained asphalt or finely-graded dirt roads? I live in Southwestern Utah and it is as hot as Hades in the summer. I would not spend hours in the sun, nor hours driving on dirt roads, but it is a question I have. What are the very best tires I could put on this vehicle for a bit more rugged terrain? And, this is the car I want; I don't want an SUV. Any suggestions?
