I'm running 285s on 18x8F/18x8R with no spacers -- and no rubbing issues.

 

Those are the stocks with 30mm offset?

 

OEM track (03-05) rims. The rims are a bit narrower than "optimal" for the 285s, but the 275 Hoosiers were fine (because of the offset bead).

I think that first350 is running 285s/295s with lightly-rolled fenders.

 

This would be for running in a BS class so no fender rolling permitted. The only difference between the track model wheels (size-wise) vs. Touring, was that the track has an 8.5 rear correct?

Thanks for all the info, I'm late in ordering tires for this season and want to make sure I'm getting the best possible tire on the car.

 

I am sure you know this, but make sure to compensate for the track temp and ambient temps for each run. those tires like to be dialed in and using a specific pressure regardless of what is going on temp wise will cost you dearly.

 

Yup, first350 is running in BSP, so he's got crazy wide wheels.

Track wheels are 18x8F/18x8.5R, Performance and Touring MT are 18x8.

If you're mounting 285/30R18s on 18x8, make sure to keep your tire guy VERY happy, since mounting the 285s are a bit challenging.

Adjusting for ambient temperatures is more important for track days than AutoX, since track days you want to get a consistent hot pressure, while AutoX you want to start with a cold pressure.

 

Yup, I'm used to dealing with Kumho 710s, this will be my first time trying out the Hoosiers.
