[Paddlewise] Primex cart

http://www.sonomaoutfitters.com/pad_acc/pri_cart.html - it's been around for
quite a while ($110-130).  Sometimes Primex cart is called Roleeze (and this
is written on its wheels), though Roleeze company also makes larger cart of
that type (Roleeze Tote). My question is: did anybody have problems with
punctures on these 10"*3" Primex wheels?  And if so, how well can it be fixed,
say, with a duct tape in field, will it hold against air pressure? I'm
thinking of getting them for my DIY cart (currently using 8"*2" non-pneumatic
wheels). I have recently read that some people switched to non-pneumatic
wheels like Paddleboy Yedo for this reason:
http://www.paddleboy.com/pages/product_pages/yedo.html .  Yedo wheel is
slightly heavier, and has bronze oiled bushing sleeve rather than plastic
bushing of Primex (can't imagine any oiled parts inside a kayak), otherwise I
don't see much difference in wheels itself (cart design doesn't bother me -
both are too bulky, in my opinion).  No affiliation with any of them.
