Default 8.50 x 6 Desser Smooth Tundra tires

I'm going with 8.50 x 6 tires for the extra height and also I'm using larger wheel pants (think GeeBee, Stearman, Waco etc.) so a larger tire is needed. I already have new 6" Matco wheels and brakes so I'm stuck with 6" and the 8.50 x 6 seems to be the tallest tires. I had 8.00 x 6 with the old smaller wheel pants and want bigger. Anyway...the size is pretty set so my question is has anyone used the Desser 22/8.50 x 6 "Tundra" Smooth tread tires? I have never used Smooth tires but see a lot of the old Wacos etc use the Smooth tires. These Desser tires are marketed as "tundra" but they are a FAA approved tire also. 1600lb load rating per tire. 120mph. (My plane will be about 1500lbs empty and 2400lbs max gross weight. What has drawn me to these tires are they fact that they are less than 10lbs each (where. Recap 8.50 x 6 is 19lbs EACH).
What's your thoughts? Think these would be a good tire for a Starduster Too? I'm ok with having to replace more often. (Id like to get a couple years out them, 100-150hrs) I will use grass when I can but will be based on concrete. IMG_4992.jpg

I know someone with a Murphy Rebel running these tyres. He likes them and they look great on the plane. 1500 lb aeroplane though. Isn't 1600 lbs too little for a 2400 lb plane?

Andrew.

Chris, on the Carbon Cub I've been flying he has a similar tire, not sure about exact dimensions but they are tundra/soft. So asphalt ops will degrade them quickly. Something to think on.

I think they would be pretty bouncy on pavement with a heavy aircraft. Also the sidewall will flex a lot and side load could shift it enough to hit wheel pants.

My wife had these on her Cub before she moved up to 26 inch Airstreaks. They are much softer than Goodyears or other treaded tires. At low pressure they will waddle a bit, like a Champ with oleo gear. Should be a good fit for the SD and they'll let you comfortably use grass runways that aren't as smooth as they should be.

I guess I need to call and see how these will handle with "normal" tire pressure. I wasn't planning on using 10-20psi like the cub STOL guys would with these tires. I was planning on about 30psi so was hoping they wouldn't be like marshmallows. Basically I want 8.50x6 tires...and was just looking at these because of weight. These are about 10lbs each vs 20lbs each for recaps. I know they will wear quicker but being FAA approved I figured they wouldn't be two landings and done. (Id be ok with these lasting two years of 50-100 hrs a year flying off turf and concrete.)

As far as the rating of 1600lbs. That's plenty id sure think? I mean that's PER tire rating not whole plane rating. Mine will be about 650-700lbs per main tire.

Any and all thoughts are appreciated. I know I don't need the extra weight of the recaps but if that's what it would take to be safe so be it. (The weight of a new tire vs recap is Very close. The recap seems about only maybe 1-2lbs more than new tires. $300for new 130 for recap. So at 170 for 2lbs or 340 for the 4lbs I'll just try and not eat so much and loose that 4lbs in the pilot seat. Now if we come to the conclusion these "tundra" would be ok at say 30psi if actually Dave weight over my current 8.00x6 tires.

Well I chickened out and just ordered some Goodyear recaps in 8.50x6. I’d still like to see these. My main concern with these would be the weaker side wall. If I wasn’t running wheel pants I think I might have given these a go but the recaps are cheaper and will be good to go for sure.

.
A solid arrival on one wheel in a crosswind could easily see 2400 lbs on a single tyre. As I understand it these tyres aren't to be used on certified Super Cubs at 1750 lbs and that is why. I understood these tyres were aimed at the LSA market (Rans S-7 etc.) to provide that segment of the market with a tyre that was lighter than those made for Part 23 planes. I'm happy to be corrected, which is why I posed my original comment as a question.

One place where lighter may not be better?

Default 8.50 x 6 Desser Smooth Tundra tires

They are “certified” now and I’ve read where people are using them on Cessna 170s etc. not sure what all else but you realize a Goodyear 8.50x6 6ply is only rated at like 2250lbs. (Hope I remember that correctly...I know I saw that on some of the 8.50x6 6ply certified tires)

I passed them up this time because I just wasn’t sure they would be stiff enough sidewalls. Also I read the rubber is very soft so may not last well at all on hard surfaces. I liked the 21/8.00x6 4ply as it was a rubber tire but it was only rated at 800lbs per tire! I asked Desser what the difference was between it and the 1600lb rated 22/8.50x6 4ply and basically got no answer other than that’s what’s marked on the side of each.
