i know this might be a stupid question, but im looking to get some new wheels for my xfire but the owners manuel(wow i just felt like a noob saying that) says to not put bigger than 18's in the front.. is it possible?????? lmk.....

 

Yes you can, I am running 19's on the front and 20's on the rear. I had to go to a lower profile tire. Keep in mind that to do so will sacrifice the ride quality somewhat IMO. Keep in mind too that if you change the offset you may have to go with a camber bolt kit to bring the aligment in to avoid wearing out the tires. I also think there have been some that have gone with 20's up front as well. I could be wrong.

 

Also keep in mind that changing from stock will affect your speedometer readouts.

It's probably not a dramtic change, but you need to be aware of it when pushing hard, or having a heated debate with your local Sheriff.

You can check the Wheels-Brakes-Tires section of the Forum, quite a few threads on going with larger wheels...

 

A 225 35 19 would work just like stock as long as you use a wheel with the same offset as the stock wheel. You would have no speedo issue or any issues at all with this size tire.

 

Speedo issues should only apply to rear wheel size. Correct??

 

Usually this is correct, but I am not sure where the Crossfire picks up the speed. As long as you keep the tire real close in overall diameter, you have nothing to worry about

 

The largest I have seen up front is a 20", what I had on my last car.

I would not recommend more than a 19 for the fronts, from personal experience
