Welcome to LOC! B) Very nice ride for a 16 year old. I assume it is the stock tire size you are looking for... 205 65 15? If so there are many choices out there. Since your in Houston, I think it's safe to take snow & ice out of the equation. However, I would suggest spending a little more for a very good brand name tire as opposed to Walmart's own brand for example or a lower line tire.
A few I would recommend that provide excellent traction, a long tread life with very good wet weather performance are the Yokohama Avid H4S at around $78 a tire. More info here...

The Yokohama YK520 (available at Discount Tire only)....several here have had very high praise for this model but no personal experience. More info here...

Another would be the Goodyear Assurance Triple Tred at $96 a tire....but Tire Rack is currently offering a $40 rebate on these (I have these on my Lexus & my wife's Subaru Forester & swear by them.....although we get a fair amount of snow & ice here in the great white north so that was a consideration as well). You would be hard pressed to beat these tires for wet weather performance however & they have a 80,000 mile treadlife. More info here...

Michelins are an excellent choice as well....but the price is over $100+ each.....I've tried to keep the price below that.
Don't forget a 4 wheel alignment when you put the new shoes on. ;) Good luck!
