Thinking about these. They are cheap and seem to do good on the rocks.

I didn't see a price. What do they cost?

$280 37" in a 15 style
$321 in a 17" style

whats your main concern? Cost factor?

I was considering these before I settled on the Baja Claws

Maxxis Trepadors

Cost is a big big part of it.

yeah, quick search shows treps around $380 each 37x12.5 17" rim
