Hoosier 255/35 - 18


Recommended Posts

Hey All,

I have a Spec Z that I have been racing in Rocky Mountain as there are enough racers to make it a fun group.  However, once outside of Rocky Mountain or Utah, there is no participation.  I'm looking at traveling a few times next year and with a few bolt on parts I can get close to the right HP/Weight ratio for ST4.

Tires are the unknown for me.  Will a Hoosier 255/35-18, mounted on a 10 inch wheel meet the requirement for being under 282mm?  I know they typically run large but I'm not sure how large and I don't want to buy a set only to find they are illegal.

I've seen a couple threads that talk tire size, but nothing specific to this set up.

Thanks for any help.

Thanks Greg.

From the Facebook group, it sounds like a Hoosier 275 mounted on a 10 inch wheel will fit the 282 measuring device. 

I'd be surprised if anything on an 11 inch wheel fit since the wheel itself is only 4mm shy of the 282 max dimension.
