Because the faster the top speed, the slower the acceleration. Changing the tyres just changes the effective gear ratio, so rather than big tyres you could just use small tyres and change the gearing.

Small tyres are lighter, cheaper, and lower so better for racing.

so is a 13 inch tire pretty good with a 54 tooth spocket to a 10 tooth clutch? my kart is tiny, and very light (i can lift it easily by my self ) maybe around 80 lbs-ish and i wiehg 165lbs . would i get a pretty good speed with a 5.5 honda clone and that gearing?
