Latest recs/experience with 15" Hoosiers?, A7 vs R7 vs Radial Slicks Options

[campbellcj]

Hey All -

When I was last actively tracking my car in 2016-18 I had switched to a Hoosier Radial Slick in a soft compound which does not seem available anymore, but there are similar models in a medium compound I think will fit.

I'm aiming to get back out there a few times this year just for fun - won't be running competitively at least at first as I shake-off the cobwebs - so I'm thinking the R7 or A7 may be better in terms of longevity and pricing. (Although previously I found the slicks and R6 lasted me around the same number of heat cycles with the slicks performing better and costing more as one would assume.)

Does anyone have recent experience or info on using the A7 for short TT/TA sessions or sprint races, around 20-25min sessions? I've never used any of the A* variants but recall hearing of folks using them on lightweight cars for non-endurance events. Was that @brant ?

I'd be open to other brands as well if the correct 15" sizes are available. I run 8's/9's and my flares can fit about a 10" section width tire.

Thanks much for any insights!

definitely the A7
those are the fastest tires I've used...
I also have a bunch of vintage legal tires in 15 that are all slower than the A7

A7 and R7 no longer vintage legal in my neck of the woods, nor SVRA

but 2nd best is the hoosier speedster
3rd best the RA1
4th best the hoosier Bias ply

if you can run the A7 I'd recommend it.
mine held up very well (30 heat cycles +... no cords... but definitely timed out on heatcycles)

I talked with the hoosier engineers when I tried them the first time
they were build for corvette's and mustangs.. all which weigh much more
our cars are easy on tires with the balanced weight bias.

I had no problems switching from the R7 to the A7 and noticed no wear problems.. but did notice how much quicker they came up to temp and grip.

a local hot shoe who always takes the podium in SCCA nationals uses them on his corvettes even.
