Need some advice on tires/wheels

That looks very good!
For reference, I'm using these in both 22mm and 30mm wide versions on my fire truck, with the included foams and Tamiya 1/14 truck rims. They have no problem carrying about 12 pounds on 6 wheels, but I don't know how they would handle beach sand. They're 85mm in outer diameter. https://www.stellamodels.com.hk/trac...u-pr-8495.html

I looked at those tires. Like the tread pattern. The ones I got have a pretty simple road tread pattern. Might be good enough for the front tires. You said you are using both 22mm wide and 30mm wide. Those you referenced look to be the 22mm version. Is that correct? What diameter is the rim? (I have rims made for a 43mm I.D. so I have some interest in not re-doing a lot. (OTOH, now is the time to make changes.) Do you have a reference for the 30mm wide tires?
