Aerospace Quiz #302
      #354589 - 10/20/12 05:08 AM

Folks,

This one surprised even me when I read it. To wit, what commercial aircraft had the largest tires ever fitted to a commercial aircraft.? Hint> It is not the post WW2 Bristol Brabazon as I would have thought.

Finally, I wonder what aircraft -- military or commercial -- has been fitted with the largest tires. I would think it would be the B-19 or B-36. Just a hunch.

Jack:
The biggest tyres I recall were on the C-124. But I am probably wrong.

Dear Randy,


That is my guess for "any" aircraft, but the B-36 is "military".

Dear Mase,

The C-124 is a military aircraft, but even then the first B-36 (and before that the one-off B-19) had a monster tire. According to the most recent issue of Air International, it is the Boeing 777-300ER. I never knew how large that aircraft was till I saw a photo of the front during a taxi and you could see the pilot and copilot's head through the cockpit windows. They looked tiny compared to the rest of the aircraft.

Finally, the 777-200LR (9,420nm) has the longest one-way, internal fuel, range of any commercial aircraft in the world. The only other mass produced aircraft that can beat (according to the article) the 777-200LR in internal fuel range is the USAF MD KC-10A.

Note> When I read about the KC-10A, I thought what about the B-52 with a +10,000 mile range? And they must be referring to the KC-10A using the fuel it takes up to refuel other aircraft during the flight????

Hi Jack:

I was just checking on the wheel dimensions on the Commercial Version of the Kalinin K-7 and the two rear tires of the three-tire truck measured 55x22 with a slightly smaller nose tire in the truck. Isn't this a bit larger than those on the 777-300ER?





I know that that there was only one (1) Commercial Kalinin K-7... but then again, there was only one (1) Douglas DC-1. <BG>

Looking forward to your confirmation on this one...

Best, John

Dear John,

They produced a commercial version of the K-7! Jeez what you learn as you grow older. I have the feeling that the one off B-19 had the largest tire of any aircraft in history. The two wheels that retracted in the wings were monsters.

Jack..According to Wikipedia...the main tire on the Douglas XB-19 was 8 ft in diamenter...whle the XB-36 main tire was 9 feet in diameter.

The XB-36 main tire was the larger, of the two aircraft.

The B-36 on dispaly at the Air Museum Of The Air Force at Dayton, Ohio, has a stand with an example of the 9 foot tire on display, with the B-36.

Jim
