Hoosier Tire Sizing: What fits, and what doesn't (Finally stepping up) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm tired of wasting street tires on the track, and finally with my job am able to step up to a decent tire.

However, my issue now goes into sizing and what is to small/to big.

I'm looking at either running a 225/45/17 Hoosier all around, or a 245/45/17 all around. The reason I say all around, is that I'd like to be able to rotate them all around instead of just side to side (although I'm not sure that's even a good idea).

I currently run 225/45/18 in the front and 245/45/18 in rear of my car (on 350z track wheels) and have no fitment issues, even with 10mm spacers up front.

However, knowing track tires, I know these will be slightly taller. I know the rear will fit, but am concerned with the front. I plan on running these on late model Mustang GT wheels.

So here are some dimensions:

Ventus RS-2: 225/40/18 Section Width 9.1 Tread Width 8.0 Diameter 25.1

Hoosier: 225/45/17 Section Width 9.6 Tread Width 8.7 Diamter 24.5
245/45/17 Section Width 9.9 Tread Width 9.4 Diamter 25.3

I'll hafta go home and do some measuring, but am just wondering if 225 wide tires will be enough for a HPDE only car, or if going 245 would be the better idea? The tires on the car now (in their sizes) work great IMO for a true street non r compound tire.

Any help is appreciated (Unsure if this is in the right section either, seems to fit a few different ones)

245/40/17 or 255/40/17 is a good tire size.

its fun enough, and you won't have any issues fitting it.

all the tires you listed are really tall

A 255/40 is as small as I'd go, Cody. If you find that you still have some room, then maybe step up to a 275/40/17... for the price you can't go wrong.

Also, go with an RA-1/NT01 over the hooiser, you'll get alot more useful life out of them without worry of flat spotting or wearing them out in 4-6 track days. I've gone through 4-5 sets of hooisers and am now on RA-1's, and will probably stick with them from now on.

245's nothing less. If need be pull the fenders. I would agree on switching to another tire because of the short life span of the hoosiers, but the grip of the hoosiers will be addicting.

ever look into victoracers? been seeing lower numbers from those than the hoosiers lately.
