LPRs ballon less because they have a shorter sidewall, I buy the premounted wheel/tire set( I suck at glueing tires) and run taped Maximizer beadlocks w/ Badland tires for bashing

Proline LRP's are also have ribs inside to reduce balooning.

AKA are low profile tires
but dont forget that LPR tires put more stress on the suspension as they dont soak up hard landings as good as standard size tires so they are really just for racing.
