    Unofficial Tech Tips for 1/16 E-Revo: Jconcepts goose bumps

    FIRST,
    The MERV is super fast out the box and I decide to play a little with tires and wheels after beating down the stock talons. I ordered some additional talons but also experimented with beadlocks and softer compound tires. I mounted J Concepts goose bumps on their beadlock rims with the stock foam and took it for a run with two NIMH packs in series and BAM Blowout:

    The tires are so soft that they balloon into saucers and pull the tire beads right off the rim. The truck is uncontrollable with the tires ballooning an it is very dangerous, particularly at speed.

    I then added a bead of silicone to the bead to help the bead stay in place and went out and ran them again. Same results.

    So the final working solution that I came up with was to tape the inside of the tires with duct tape just like in the video below. Do this and add a silicone bead to the tire bead and the setup works. Only downside is the extra time and weight of the tape and silicone.

    You can see the effect of taping tires on this video:

    Night and day difference! I really recommend taping these soft tires whether you use bead lock or glued rims, especially when using dual packs in series or Lipos.

    BTW if weight is really a concern there is the option of using 3 X 10 MM Titanium screws from Lunsford: http://www.lunsfordracing.com/mm5/me..._Code=MMBUTTON
    This is a really really expensive option however because you need 16 per wheel. The cost balloons (no pun intended) to around $20 per wheel in screws alone. There are many better options out there for that kind of money!

    I was considering buying a set of j concepts goose bumps tires meant for a 1/10 rear buggy application and just mounting them on 2.2 inch wheels. I dont know if these would be stiffer than the 1/16 mini e revo specific tires or not. But i will buy the harder compound tire. My question tho was how the tire performed. They offer lots of grip onroad? On dirt? How big are the tread blocks in comparison to the stock talons?

    The Goosebumps for the 1/16 (2.2 wheels) are way to soft for on-road! With the power of the brushless system you will rip the tread right off of them but in the dirt they grip like a vice on soft and medium surfaces. I also hear they do well in the packed stuff.
