we have to run harder tires than competitorscan you set kart up so you can use softer tires like less left lower cross?
softer tires on our kart seems to wear [ feather quicker] need harder to show better wear] some karts are running 45 duro and we are at 54Trying to confirm your question, your asking because you have to run a harder tire is there anything you can do with the set-up to help compensate for that ?
Then I'm curious WHY you have to run harder tires ? your not allowed to prep ?
they are suppose to feather a little, if you come off the track and the tire is slick its not workingsofter tires on our kart seems to wear [ feather quicker] need harder to show better wear] some karts are running 45 duro and we are at 54
Like it and I'll add could just be the way there using it vs yourself, also could be there checking at different area of tire than you, don't get hung up on just duro numbers regardless.Just because your competitors tell you there tires duro at 54 and your are 45 that may not be the case , if they're using an Intercomp duro and you're using a longacre that right there can be the issue ....a longacre will read higher # then the Intercomp and if you're chasing there #s that's why you think you need a harder tire ....
Also if one has more air than other it will read higher.and just to clarify , the 2 durometers wont be 9 points different but they are different , Another variable is rubber thickness , if your tires are thin you can actually be reading cords
