Grah is probably right. In which case, I would suggest giving them a soak anyway, as there is nothing to be lost. It's definitely worth a try.
Check them regularly when soaking or you might end up just dissolving them off the rims in a pool of stinking sludge!
I smeared some Fly classics with 3in1. It softened them just fine but it also expanded the rubber a fraction...enough to make them slightly too big to snug onto the hubs. You solve one problem and get another.
Yes, if the tyres are that dry you need to buy new ones. Nothing could save them!
Before adding any additives to tyres always glue the tyres to the hubs - this is a worthwhile precuation for all cars you race competitively with but is essential if you starting rubbing things in to the tyres.
i find that if you sparay the whole back axel for abou 1/2 to 1 sec with wd40 then rub it all the way round the tyres and rub it in then leave to dry check the tyres , when they are dry they got as much as twice as grippy on one scalex car
well worth a try considering a small can of wd40 only costs £1.50 where i live, ill have to try using lighter fluid as well
