FIRST ORDER --- 5 STARS+ ALL DAY LONG --- September 23, 2022Cenipar 20x8.00-8'' Inner Tubes,Tire Replacement Inner Tubes for Heavy Duty Cart,Such as Trunk, Tractor, Garden Carts,Golf Cart, Mowers, with TR13 Straight Valve Stem,Pack of 2 ~ $21.99So I have quite a bit of experience with tubes aside from having a lot of my own equipment and having worked in shops. I've tubed hundreds if not thousands of tires. And after all that I'm a pretty die hard Carlisle guy when it comes to tubes. But a bit of a time crunch and these being 2 day delivery, and 2 for the price of 1 Carlisle tube with good reviews I rolled the dice. And I must say I'm skeptical but they do feel like surprisingly nice quality tubes.Feel like good quality rubber and nice thickness, and the thickness is consistent. I haven't used the tractor I put them in much yet, but got them in with no issues and they are holding air after 2 days. And being they felt surprisingly nice my hopes are cautiously optimistic. And I use the tractor they're in quite a bit not only cutting, a tenant cuts with it, and it also pulls a 4x8 trailer moving yard waste and sometimes logs. And I'm not easy on equipment so these will be put through the paces before fall is out.If I haven't edited this with one star and a detailed failure analysis you can assume they're holding up. I put them in tires that are in near perfect shape but just had slow leaks and are on nice smooth clean rims holding paint and no burrs. Tires were thoroughly checked for anything poking through, everything was clean and dry, and neither tube was disturbed during installation. So short of a puncture from me running over a nail or something I will be highly agitated if they don't last forever.A word of warning on packaging:These came completely bare in a smallish box. Not wrapped in anything, not so much as even packing paper or a cheap plastic bag... so be careful opening the box with a blade... a tube could literally be right up against the back of the tape you're cutting.------------------------------------------------------SECOND ORDER --- June 12 2023 --- 3 maybe 4 stars so dropped a star total4.80/4.00-8" Tire Inner Tubes by Cenipar For Heavy Duty Cart,Like Hand Trucks, Garden Carts,Mowers And More, Pack of 2-25% $11.99First the 20x8-8s reviewed above are still going strong with no issues, I'd recommend them 100%. So after being pretty impressed with those I searched for Cenipar when I needed a 4.80x4-8. And with that size the tube itself feels great, just like the other, nice and thick good rubber, but the valve stem looks a bit flimsy. Kind of on the thin side, particularly at the base. Normally the valve stem will be a bit thicker at the base which is good to handle the torsion and rubbing it will inevitably get at the valve hole of the rim. These are straight all the way down. That being said the one I used is working fine so far, and the overall tube rubber was nice and thick and consistent, but I see the thin-at-the-base valve stem as a weak spot and potential point of failure.So revised summary...Still 5 stars for the 20x8-8, looked great in every way and still holding up to rough service... but dropped a star for the 4.80x4-8 having a less than impressive valve stem. You could still do way worse for a tube, it's not horrible. Main takeaway - some varying specs from size to size. Even at that, the one nit-pick with the 4.80x4-8 may still not be a deal breaker for the price and convenience, especially if the last.And again if there's no failure analysis update you can assume they are still going.

I liked the fact these tubes have metal air stems. The rubber stems on tubes seem to be a weak point and are prone to leaking.

Good tubes thanks

Perfect transaction

Really nice heavy duty tubes and customer service.
