Tires for a Baja Bouncer?

These are observations only, what matters is the starting axle & wheel quality plus a good fit for the chassis; something that isn't tight but also not sloppy side-to-side. If an ACTUAL racer replies to you and says different things, pay more attention to them

Good wheels come in plenty of different types so when you're showing me TRAP5 versus PR5 that's two examples out of literally millions even within those styles. You'll find gems and duds in both. This is why testing and wheel farming are important building steps. If you insist on TRAP5 (first closeup photo) and will race with a lot of narrow lanes, sand the sides to get rid of those white bits until they're flush with the rest of the wheel  

On the subject of wheel farming, perhaps look at cars you have from 5-packs and multipacks. Indonesian factories do something different on average with axles & wheels compared to Malaysia, where single card mainlines come from 

The Trap5 is notorious for climbing the track wall and causing the car to jump the track, it doesn't happen all the time but there us always a chance it does with that particular wheel.
