Hello, I'm going to buy a racing wheel soon, and I was wondering which racing game should I get? Which one is the best? Be specific please.

Don't get any racing games, just use the wheel when you're playing regular games.  Be sure to show your friends how awesome you are at moving in games like Counter-Strike.

Depends on what type of racing you speak of....Nascar, F1, Rally......?????

Grid comes out soon, looks good
 
Very VERY slighlt hints at GT5 on pc....
 
There are also some very nice sims i have heard about but havnt tried yet (and cant remember their names).  
 
I want a G25 wheel to race on sims but its too expensive and i dont have the time for sims atm.

I have a Logitech G25 and it is amazing. At first i did think it was too expensive and thought how much of a difference could it make??? but... it makes a hell of a difference! So much better and i'm now glad i spent the stupidly obscene amount of money it costs
 
I play GTR1 & 2, Live for Speed and Richard Burns Rally. All 3 are GREAT games, if maybe i prefer Live For Speed just a litte bit more (seems a little bit more realistic), if it wasnt for that damn crap AI it would be perfect-ish!
Multiplayer is good fun though
 
Grid does look good but like they always say never judge a game by its previews. I did that with Colin McRae Dirt and how bitterly dissapointed i was.. turned out to be a really crap game! lol

I'd be surprised to see GT5 on the PC anytime soon - or indeed at all.   Sony need a big exclusive title to bolster the flagging sales of the PS3.
 
 
In terms of racing games for the PC, Test Drive:Unlimited is good for a laugh and you can even just go for a quiet drive if you don't fancy racing (i.e. are too drunk).  If you want more of a simulation, have a look at Race.  It has a short demo so you can try it out before you buy.

 
Need for Speed Porsche Unleashed, ofc. BC graphics ofc but try to do the factory driver and the career with a Steering Wheel.  
Man, i still play that old thing. For me, after that, every car game was worst in terms of maneuverability and phisics of the car it self.
 
Or try any of the GTA series with a heavy dose of moonshine.

Check out Trackmania. It's free so it doesn't matter even if you hate it!
 
I found it refreshing to play a racing game that revolves so heavily around jumps and stunts!

I have trackmania, it's pretty good  if different. Project torque is another free one.

Dirt was ok but got boreing quick.

Yeah trackmania is pretty good if arcadey in handling, grid is good (pc zone reviewed it and said it was the best pure racer they'd played) and also gt legends is supposed to be the daddy for classic cars.

I only use a normal gamepad for racing games but since im a fan of trucking i like to use the wheel for the 18 wheels of steel series or some other type of simulation .

Hey trackmania is awesome, i like it very much. If you are thinking of buying any racing wheel, then you should go for trackmania.
