Hi all,
I've got a question regarding suitable rims to use with Goodyear Landspeed Eagle tires (specs in link below). We're currently assessing options for our 1000cc (motorcycle) streamliner’s front steering system (hub-centre vs leading link) and whichever we select will obviously influence the design of the wheel. I've got a couple of questions on our wheel options below:
1. If we select a hub-centre design, does anyone know of off-the-shelf wheels that suit these tires and are compatible with a hub, or will we have to get custom rims machined?
2. What are the advantages of a solid rim design (i.e. a wheel with a tyre but no spokes) vs a spoked design?
3. Would anyone recommend any wheels which they have used, that suit the 21 inch Goodyear Eagle tyre (link to spec below).
If anyone could help/offer advice based on their experiences, it would be much appreciated!

Ross...have you looked at the following website? He is using the same tire as you.

Thanks Bill, we used this website a lot in the early stages of the streamliner design last year - had completely forgotten about it, thanks for the reminder!

I have found that going with HCS has it's advantages, but you have to think of cost as second fiddle.
My thinking was that HCS would be more stable running, thus Safer, but that means you don't mind spending the extra money it cost to go that route.
We made our own Center Hubs and wheels, and they came out very nice, but we could have gone with front forks for less than 1/4th the cost.
One of the biggest advantages on the build is, it gets the forks out of the way for doing the body work.
I don't know much about Leading link or what it takes to build.
Our front wheel is set up for shortest MT LSR tire.
Hope this is food for thought

If you would consider going with the newer Goodyear 17 inch top fuel front tire, which SCTA and Goodyear both approve for over 300 mph you might consider going with the forged aluminum wheel from All American Wheel, http://www.allamericanwheel.com/index.html, they make forged aluminum wheels for motorcycles so the tire mounting contour is for motorcycle tires. They have a 17 x 3.5 which should work for the Goodyear 2904 tire which has a motorcycle style mounting bead. I am planning to use them on my little lakester and they are about $200 each and are exceptional quality.

interesting to ponder the effect of having the sidecar wheel has on
stability vs only one rear wheel in line with front....

.......or no tire at all :evil:

Sorry to be so late to this party. I am gratified that folks are using my website. I learned a lot from experienced guys, as well as by doing. The website is my way to return the favor. I have unfortunately not been keeping my website up to date (my bad).
On the rear I still plan to use the Goodyear 2286 28x4.5-15 tire mounted on Centerline aluminum 15-inch wheels made for early Volkswagens. These wheels have about a 6.3-inch (160 mm) diameter center hole, which fits nicely over a sprocket carrier and also over my custom HCS front hub. The 2286 is (using polite language) difficult to get on the rim; there is a danger of damage to the rim or the tire. I ended up drilling out the rivets and replacing them with bolts. Problem solved, albeit with considerable work! I spread a thin layer silicone sealer over a large area between the wheel halves during assembly, instead of the large OEM silicone caulk “rope” that I think could fly out of the rim valley at speed.
On the front I am in the process of switching from Goodyear 2282 21x5-15 to the new Goodyear D2904 22x4-17 Frontrunner. It has a more rounded cross-section than M/T or Goodyear Land Speed tires, and also costs less. Admittedly the fastest guys have used such tires on 2-wheel liners, which were the best option at the time, but I still worry about weird handling due to jumping from one shoulder to the other of flat tread tires. As Rex mentions, Goodyear and SCTA have authorized the new D2904 Frontrunner for LSR use up to 300 mph, at 90 psi and less than 1200 lbs radial load. This tire requires a motorcycle wheel bead shape, which has a slightly smaller than a car wheel bead shape, as discussed in detail on another forum thread. Perhaps a car wheel could be modified. A custom wheel can easily be had - be sure to get the correct motorcycle bead. I bought a pair of older model Weld Racing dragster front wheels on eBay. These wheels have the appropriate bead shape, with spindle hubs and a solid disk center - no spokes. I milled out most of the center section (does anybody need a set of spindles?) and made an aluminum adapter disk to fit the Weld rim and my hub (I am stuck with the early VW 5x205 bolt pattern). In retrospect, a custom wheel would have been a better option, taking my time into account. I will look at the All American Wheel that Rex mentioned - I did not know about it.
Overachiever John Buddenbaum used link front suspension/steering on his IMHO brilliant BUDDFAB motorcycle streamliner.
BTW, the current SCTA S-F-1000 and the AMA S-AF-1000 records were set in 1967 by a guy (now deceased) by the name of B. Munro, as is loosely documented in the entertaining movie "World’s Fastest Indian" and more factually in a book entitled "One Good Run." There is a strong sentiment among many LSR people that this record should not be broken. Just saying.
I hope to see you on the salt - though probably not this year, unless it dries out soon.

If "they" want Burts record to stay in the record book then put it in pushrod class, vintage class. I say go for it, it is long overdue. The 1000cc production record is almost 200mph. Boy this ought to stir up some caca.
-
The record is not protected. It cannot be broken. Many attempts at this 1000cc record have resulted in broken equipment or crashes, ask Gary Hensley.
If running against old Burt it might be wise the have the Ghost Buster's Eco Lab standing by.

Interesting comment, DW. Burklund said pretty much the same thing. {Ominous music in background}
