tire size for wheels

[ktm]

Maybe someone could post what size tires theyr using and how much hp they have? I'm looking to make around 300-330hp after my stroker.

Ain't gonna happen, unless you are talking about flywheel horspower.

You do not need 245s for your application if it is a street car. I ran 225/60R14s in my turbo setup for a little while and had no problem with them. At the time I was producing around 320 wheel ft-lbs. The 225s were great but the sidewall profile was a bit too high for hard cornering.

You do not want to run a staggered setup either, unless you like to change your tires much more frequently. You will lose the ability to do a 4 corner rotate with a staggered setup.

I am now running 16x8 +10 with BFG G-force 245/50s. The tires were new when I bought the wheels from a member at Hybridz. I rub the spring perch in the rear and the front. I needed to run spacers and trim the lip of the spring perch just a tad in the front and rear to clear the springs, but I will also need flares since the edge of the tire is flush with the fender lip. I had to trim the lower valence as well to get clearance for sharp turns.

In the end it is your car and you can do what you like, but 245s are overkill for your application. Remember that unsprung weight plays a significant role in your cars performance. There is a weight difference between 225s and 245s, 15s versus 16s and 17s, etc.
