Lunchbox Wheels and Tyres with a twist

[Country Mike]

I've built a tonka bronco using a stretched lunchbox chassis. However got issues with the stock lunchbox tyres being flat. Apart from foaming them, is there available a tyre which is more 4x4 than mud digger or a wheel / tyre combo made by tamiya which is suitable? 

Basically, with the tyre practically flat, the steering on grass is useless as the poor servo is struggling so a tyre similar profile maybe with reduced width? I know the brats aren't the same offset etc.

Here's a teaser.

Don't take this the wrong way, but something about your creation really reminds me of a Popemobile!

with regards to your tyre issue have you considered gluing up the valve holes in the wheels (if yours have them) & then gluing the tyres to the rims - Effectivley making them air filled so they don't collapse?

I think the gluing may be a good idea. 

I've also had postman pat van too. I paid £40 for the tonka 6 months a go. I lacquered the rust. It's ace.

Why not buy a servo with more torque rather than trying to get wheels/tires that are skinnier? Or do you want a different looking tire as well?

[Country Mike]

Better tyre too.

Gotcha. A different servo won't do much for that
