Where can I find a list of tires and how they rank in order from softer to harder?

Thanks...

You're probably not going to find a reliable list such as that, David. Might be time to buy a durometer.

The raw rubber sheet used to make tires varies quite a bit, especially from batch to batch, is one reason.

A rough guide (softest to hardest) is untreated, treated, Thunder, Wonder. These are the ones I use most frequently. There are soft Wonders that have recently come out as well. There are brands that have their own "type" of rubber as well (like the Kelly Euro and Retro tires). But the ones I mentioned are pretty universal names for the rubber.
 
Different brands can feel a bit different, different hub sizes can effect how they grip, and as Greg mentioned, different batches can have variations. And sometimes a track can have a different level of grip than it usually has.
 
Best advice is see what everyone else is running and start there, then try one step harder or softer to see how your car reacts. Don't be afraid to think outside the box. 
 
If you're looking for a comprehensive list, that might tough to come by.

Thanks...

Alpha "Piranha" work well on BPR's flat track. You may need to try different hub sizes to see what your car likes. Sometimes we use JK 8703s(I think). Mostly the Piranhas though.

David,

John gave you the best advice: "... see what everyone else is running and start there, then try one step harder or softer to see how your car reacts."

What tire works at one track may not work well or at all at another. What worked last week may not work this week or next. Temperature, humidity, track surface finish, type/level of spray glue (if used), type of car, gearing, type of motor, hub size, track power set-up...

There are just too many variables involved in tire selection for any advice we might give you from afar to be helpful... except in emptying your wallet or running up your charge card.

Dave,

What kind of cars are you running?
A motor is only as fast as the chassis it's in.

Ask the fastest guy at the flat track - do this when they are sitting down in their pit. Ask them to show you.  

Then go buy them at the counter - and ask the owner what they are using today for a second set to test.

 

Last night I asked - was told small hub treated.  I picked Kelly Retro small hub and they were great. (hillclimb)  I did test six sets/sizes/manufacturers on two cars - the two cars liked different tires... small Retro on 98 gram C21 GTP, large Retro on 88 gram Flexi GT Coupe. SMH, but the clock told me what to use.

 

Dale wouldn't look over my car. I loved hearing, "Fronts are soon to be ruled on and until then..."  

 

Haha - I must have got a lucky motor off the wall an hour earlier!

David,

 

The info above is all good.

 

The go-to tires for a Retro car on a flat track are all untreated.
