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.
I use these wheels for carts: http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=6970&productId=13794&R=13794 Cheap ($8 ea) and work very nicely. K
It's a good one; ball bearings work nicely even without any lubricant. If they really have ball bearings on this wheel, as they write. Almost the same surface area as 10"*3" Primex (OD*W), which they also have, for $10: http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId =6970&productId=18846&R=18846 . Don't know if they ship to Canada (after shipping and all dues it would cost almost the same as CDN 25 Primex in local store). Though, quality might be better than Primex, made in you-know-where. Or, may be, not :-).... > I use these wheels for carts: > > http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId =6970&productId=13794&R=13794 > > Cheap ($8 ea) and work very nicely. > > K

Given that the cart is presumably used for short distances and low speeds, bearing lubricant will be irrelevant. They'd have to be well sealed to keep out sand, though. > Almost > the same surface area as 10"*3" Primex (OD*W), which they also have, > for $10: When dealing with rolling resistance, diameter matters more than width, especially in rough terrain and sand.

I can't figure out all the forces involved, though it looks like surface area (3.14D*W) determines whether it would eventually roll or sink in sand. You're right, diameter reduces rolling resistance (with given surface). Have to think about either of those from Northern Tool - 12.5*2.25 (Keith is using them) or 10*3. Rolling resistance should be good enough with bearings on any of these wheels (I can roll 8" wheels without bearings under partially loaded kauak, when they don't sink in sand or gravel). Hell knows how well their bearings are sealed from sand. Wheels with large D, 12" or more, are difficult to store in a kayak, even when they have less W - they are not the heaviest thing in my gear, and I like storing them farther in the bow or stern, and hull is narrow there.
