    Default Tire suggestions?

    I need to upgrade my old stock 20x 7.00-8 Taiwanese tires, but looking for an alternative to the Desser Aero Classic 27.510/8. At 20.5 lb. each, they would be adding roughly 15lb. per side (if I go tubeless). Everything I can find is for a 6" wheel. I would really rather just put some new tires on my existing 8" wheels than change over to new wheels, brakes, mastercylinders, etc.

    I have found a couple of places which sell the stock size "Kitfox Tire" but with a 2-ply load rating of 195 lb. they sound even worse than what came with my project. Something like THIS would be good if only I could find it in an 8" wheel size.

    Does anybody know if the original Matco 8" wheel can be used tubeless?

    This is what my original right side tire looked like after some taxi testing and 1 flight. The pressure was spot on, and there was only a tiny patch of cord showing beforehand. It blew out while taxiing at low speed.

    Those are not matco wheels. They are Douglas ATV wheels and can be used tubeless. You can put on any ATV, golf cart, lawn mower,etc. Tire on those. No reason you can't run one with knobby treads, or you could buff the treads off. Look at golf cart tires which can be found with less obnoxious treads.

    My KF3 had trailer tires on those rims. They fit inside the Kitfox wheel pants. I liked them OK but they were very grippy on paved runways. On the other hand wear was not a problem.

    My KF4 project has spring gear but the same kind of wheels. If I keep the short wings then I'll put pants on too. If nothing else the pants keep the plane cleaner. There are two Carlisle 18x9.50-8 mower tires I think might work for me. The smooth one is part # 5109811 . The straight ribbed one is part # 518081. They both have a load rating of 1020 lbs and weigh 10-11 lbs each.

    I run Nanco Slick tires, 21x12R8. I used to buy them from Amazon but they don't seem to have them anymore. I did a web search and came up with this link, I am sure there is plenty more places that sell them. They look good and work GREAT, I love the "squish" they make on a wheel landing on gravel, and 10 lbs isn't bad.

    They don't have them. They are not reliably available anywhere right now and are probably on a ship sitting offshore somewhere. I was able to get one pair a few months ago but while looking for another pair all avenues are coming up empty. Alternate size are available like 18x9.50-8 but the Nanco N800's are a bust at least for me.

    That is unfortunate. I hope they make a come back before I need new tires. I still recommend them if anyone can find them.

    I had the Nanco tires on my Model IV-1200 during the entire build, but in the back of my mind, there was this nagging "is it TRULY SAFE" to fly with a set of tires rated for less than half the weight of your aircraft? I know people have done it for years, but....

    I ended up buying and now flying a pair of
    "Trac-Gard C/R" Model N777, in the 18x9.50-8 size. These are NOT bald, and have 8 each very shallow ribs for the tread. About $50 each.

    I run them at 10 pounds of air. These tires are EACH rated at 1,040 pounds weight capacity at 24 psi. They track beautifully and are excellent so far. I have them on the wheels that came with my original kit in 1993.

    Thanks. I have been checking about once a week many vendors. Last checked Walmart a couple days ago and they were listed as out of stock. Just ordered a pair.

    355 each is a little more than (not less than) half the weight of a 1050 lb plane (710 for a pair). I agree that it is less than gross and is cause for contemplation. THAT definitely comes down to the operator. I will run them and am not offended by differing opinion. When I was in school (college type, drop out) I remember learning that things like tires canít be engineered, 3 axis variables plus time. They are designed, tested, destroyed, redesigned, underrated, and delivered. Iíll certainly be eating crow if I ball my plane up because of a blow outÖ
