Tyre choices


Lyndon

Recommended Posts

Hi Lyndon, I used the Carslisle tyres and with 6 psi in them they stand 18.5 inches tall. A lot of trouble, expense

 

And weight to go to for an extra 2 inches in height if you import them. Carslisle's are available here.

Thanks for all the replies. Carlisles are available here ???. Who has them. Is that size ok to run in front. A member here has two for sale. If they suit the front I probably agree all three the same light and not to dear

Perhaps analyse your intended landing places. Soft? Rough? Combinations of those parameters? Think of it in terms of tyre print on the ground and radius of tyres for handling rougher surfaces and that might help your decision. Larger tyres better for rolling over stuff but downsides too; weight, drag, and higher loading on axles and other associated structures. All a compromise like everything else.

Does anyone know the weight of the carslisiles tyres ???.Does it fit the front fork width wise

 

Lyndon

Hi Lyndon,

You can get a factory made wide fork and axle (ask for the strength mod axle) to fit the Carlyle tyres from Reg at Aerokits, he usually has them in stock.

Yep I'm onto to wide fork. Be nice not to spend that money if not needed. I have bought it for a rough strip plane. A bit of speed does not concern me. Of course weight does. The Cart tyres seem very light. So maybe spend the 250 or so on the fork and axle. Then three cart tyres and carry a spare tube. I have three in the kit I'm not using nd I'm sure will work in a bind.

Hi LyndonI imported these direct from Desser Tire and Rubber in the states, their service was great. The mains are Aero Classic brand, only for LSA and experimental and so can't be put on a certified GA plane. The Condor though is OK for that and came with a release form, not that it is needed for microlight here.

 

Like lots of things in life the mains aren't quite 21" but close enough.

 

Landed price with tubes was$900NZD, was a lot cheaper than trying to source them here.

 

Yep, probably cost me a few knots but didn't get this frame to go fast. Did add a few pounds but well, well, worth it for strip work. The aircraft has been landed on gravel bars and the like and I also gleaned a bit more prop clearance from the change.

Hi Ultralights and Fallowdeer, any idea what the "velocity cost" is for those tyres over the ICP standards ones?

I got Desser to ship to the NZ Post depot they run in the states, is there an equivalent you can use?

 

Bound to have lost some speed with all that extra drag but if you were worried about that then you'd be flying some other type.

Enzed Post has a system where you can by North American products and have them sent to a quasi address in the United States. Then, for a fee, NZ Post sends the item(s) to New Zealand. Everyone who uses their system is issued a unique address so there are no mix ups. For instance, Joe Bloggs in Te Puke won't end up with fallowdeer's new aircraft tyres (tires if they are from the USA).

 

It is a really good service because there are quite a few traders in North America who say "we don't ship overseas". This isn't an issue because NZ Post operates an address in the United States on behalf of all their registered customers.

The operation is called YouShop and it is brilliant - not only does it solve the problem of traders who wont ship overseas - it also means that you can often take advantage of "free postage in the continental United States" which is often available. You also avoid the huge shipping costs charged by many US traders as YouShop only charges nominal fees to ship to NZ. If the value of your goods is over $400 YouShop will charge GST which means that you dont then have the problem of customs clearance when the goods arrive in NZ. All in all a very good solution and one I have used many times. Especially good for importing aircraft parts which seems to be a regular occurrence!

most traders who dont ship overseas do it for reason of free trade agreements, if their product can be sold here, (usually for a lot more) then they will not ship to that country, expecting you to buy it here (for a lot more)

 

as for the speed penalty, i have no idea at the moment, as i have yet to fly with them fitted. havnt worked on the Savvy for a few months now, waiting for the summer uni holidays to get back into it.. but i am pretty sure there wont be a speed penalty, well a negligible one, as the Savvy is overpowered with 100 Hp up front, but im certain it will be a fuel burn penalty. of at least 1 Ltr/hour. if not more. Before the slick dessers, i was planning on 18L/Hr with the 600X6 Condors. at 87 Kts 5100Rpm. with the 850's im assuming 19 to 20 at the same RPM and similar speed. but test flying after all the mods will get the true figures.
