I've not driven on bias ply Hoosiers, but I remember them being the hot ticket prior to the Hoosier radials.

205/60-14's might rub a bit on a Miata. They're not "too" wide, but they're out there, and they're really tall. You'll also take a 4% gearing hit. You're making a momentum car into a REAL momentum car!

Daisies offer a lot of clearance..

They are actually Non-Metric.. I estimated at that size since if I said the real size " 24.0/7.0x14" (designed for a spec 6" rim) most of this list would look at me sideways. I have 12 tires on daisies for the car now 4 are 185/65-14 (on the car) and 8 are 185-60-14 (stock size) but 4 of them are snow tires and will not last a day in this heat. I actually ran a backward search of my old Hoosier part numbers. and they USED to make a 215-60-14 that had these exact dimensions. 9" section width on 6" rim.. that will drop with the wheel size change. so assume we are going up 1.5" in section width.. I measured clearance between current tire and spring (1.4") and wheel well under full compression (1.3") .75 on each side of section width will still leave 1/2" of clearance all around..



185/65-14, is 23.5 OD. and I'm going to 24.0 OD.. (like 2% change) should be fine.. I am just waiting to commit. the daisies are 5.5" wide. so close enough.

I think this whippersnapper just called me old.... :? So that I can preserve the excuse, I've never driven on a bias ply autocross tire, and it's been a long time since I've driven on regular bias plies. I did autocross on snow tires a couple of times...mostly in the snow.
