Just because nobody had made rubber tyres for 12th scale pan cars yet does not mean it is not feasible.
is you 18th scale 4wd? or 2wd? if it's 4wd there is your traction and I bet the weight is balanced 50/50 or somewhat close. all the weight on a 12th or what would you figure guys 25/75 rear bias. so the front tires do not have enough weight on them to warm up. plus you are still at a power different in 12th vs 18th. put a mamba system in your 18th and try to hold on. then you'll know what it's like to have a 8x1 in a 12th scale. and I don't consider 18th scale racing that's playing the surfaces are bumpy enough for 12th scale a normal carpet track is like offroad for a 18th scale.
