So all the advice is to use NSR tyres for your fast cars, but when a packet of 4 Supergrips contains the following three examples, you have to question their manufacturing methods.

   

I can't remember where I bought these from, but the fact they even made it into the pack puts me off spending my money with them.

They’ll glue & true nicely 

Honest.

Place the deformed side to the back of the hub.

Really???

I thought we got excited about untwisting twisted chassis, but it's ok to run on these with a bit of sandpapering!

I started a thread on slot.it tyres a while back.
It drifted off topic but but there is useful NSR tyre info in there. 
"A bit of sandpapering " will never be enough prep for supers/ultras.

My 2021 proxy cars have all been shod with NSR 5260 to date.
I've had problems with the cars (guides, centre of gravity, ground clearance) but not with the tyres.

I meant gluing and truing of course, but to me, these examples cannot be as effective as some completely round ones.

However, I will g+t them on some hubs and will compare them against some perfectly round N22s.

The older nsr tyres cannot be simply skimmed. 
Only the full glue and true treatment gives them any hope of working. 
Any pair of tyres has to be trued to the same diameter on the wheel to be ready for the track.
NSR tyre prep is where knowledge,  money ( a Hudy ) and patience pays dividends. 

I borrow a truer when I have to work with NSR supers, but the truth is, they are a lot of work to get right.
Consequently, I use NSR reds for club racing and 5260s when the host event or club forbids non-black tyres.

I’ve found the NSR UltraGrips glue & true nicely on my DIY truer (here).The harder SuperGrips need a bit more work. Both need lots of patience - as do any tyres on that set-up. I’m sure a Hudy tyre truer will get them ship-shape much quicker.

Whatever I do, I still think there will be dimple in the surface of the tyre due to the imperfection.

If you're just making a runner for your home track? They will do fine.

If you're entering a competition? Get better tires and put those aside for a home-track car. You'll lose sleep over it.

You're in a bind because you can't send them back.

The Hudy will teach them a lesson they'll never forget!

I need to make them a bit narrower on the inside edge, so will try out the little needle tyre cutter on the Hudy.
And I do need to take a bit off the diameter to get them to the size I want. So I might end up without any imperfections after all.

Then I'll have a N22 / Supergrip showdown!
