About this part

Sidewall Support Overview:

JConcepts Truck LP Tire Inner Sidewall Support Adaptor are a great option for ultimate sidewall support. On tracks with higher traction, the sidewall can deflect causing oversteer and inconsistencies. Gluing these into the inside of the sidewall makes the sidewall of the tire much harder helping to reduce traction rolling. In addition, when conditions are bumpy or dusty, the added support drives smoother and with more consistency. Package includes four inner sidewall support adapters.


Note: These inserts have been designed to work specifically for the JConcepts Smoothie LP 2 (#JCO4049-06)

Features:

  • Precise, fit and finish shaped to tire carcass
  • Rubber material, bonds easily with glue
  • Interlocking features to align inside tire body

Work as advertised and definitely help with high bite blue grooved dirt tracks. I used these to help with traction roll which they did help. These are only for LP smoothies so I would not try to mount these on any other type of tire. Do this at your own risks but for LP smoothies fronts with RM2 foams all the way around seams to be a killer combo for me. Hope this helps!

I figured these would be somewhat rigid to reduce sidewall flex as advertised, but they are very flimsy and doubt they would do anything. Unfortunately I won't be using them to find out because they don't fit anything but the smoothie2 tires as it's labeled on the package but not mentioned on the website description.
