    Aluminium or Nylon wheels ?

    Hi,

    I am looking for wheels for my large vehicle. ( GEARS-SMP )

    Wheel + tire height should be around 17cm (~6.7").

    The vehicle will be moving slow, will carry 20kg (~44 lb) max and may have falls up to 20cm (~7.87").

    Trencher X 3.8" (Traxxas Style Bead) All Terrain Tires Mounted look great, but I worry if it can handle the weight and the falls.

    So, should I go with aluminium wheels instead ? Are they tougher ?

    I am worried that nylon could break during a competition. In the contrast aluminium wheels would just bend and endure another 20 minutes, so I can change them after.

    Also, aluminium wheels suggestions are kindly welcome.

    Sorry if that's a lot of questions.

    Thanks in advance,
    John.

    With the right nylon wheels u won't have any problems. I'm thinking 1/5 nylon bead lock wheels are going to be the strongest option.
    for example the losi 5ive is 17kg and think of the abuse they get...

    20kg sounds very heavy. If u can get it lighter u will able to use a bigger variety of wheels more suited to low speeds with higher traction
    Is that the exact chassis u are using or are u making your own??

    Thanks for answering.

    I already have the chassis in the link. Probably I could go down to 16kg to respect chassis's manufacturer recommendations.
    Losi 5ive seems very tough. Have you any wheels recommendation ?

    What's wrong with the manufactures wheels???

    what type of mounting system do they have?

    I don't know if wheel material is tough enough. Also, I want to replace the tires with higher traction ones. In any case I will need spare wheels and tires, so I think it would be better to opt out for better quality ones.

    As for mounting system, it uses these hubs Click image for larger version.

    Hummm that's a standard 1/8 rc mounting size..... I just don't know if the 17mm wheels are going to be strong enough.
    can u get a 24mm hex?

    I will have to change them either way, because different motors will have different shaft .

    im assuming the motors have a gear reduction gearbox on the end, are they part of the motors?

    I think it's something like this: http://www.gearseds.com/encoder_motor.html

    Do you mean what is the problem with the motors ? I am looking for brushless ones.

    Don't go brushless unless u plan to spend out big for sensored motors.... Sensorless motors have a minimum running speed. So at very low speeds they are not preportional, it's on or off and can make smooth transitions from rocks to dirt impossible

    I will probably go for brushless because the vehicle will carry sensitive equipment and I want efficiency (battery-powered). I don't expect them to be cheap, but thanks for the tip.

    I have the full kit , but I will change wheels/tires , motors and the box will have some additions/modifications.
