Not to my knowledge. It would take a major investment for a tire manufacturer to obtain DOT approval for a new tire, and bicycles are not under the mandate of the department of transportation anyway - they are considered toys...

Bicycle tires are not required to meet DOT regulations at all, so you're not going to find true bicycle tires with DOT ratings.
In the USA, bicycles are regulated by the Consumer Product Safety Commision (C.P.S.C.). The only information on bicycle safety standards you will find will be on the CPSC website.

It is possible that there are some small motorcycle or moped tires that would be close to the same overall diameter and width as a 26" MTB tire, but they will probably not fit on a bicycle rim.

if you are looking for the DOT only
it's been dicussed here much in the past
they are a no go for bicycles at this time as far as has been seen here
thinking that if one (DOT sizes) were to be found in proper MB size
it would be made in Japan
if you truly need the DOT check with some Japanese tire dealers
they make over there many many many different sizes for mop heads etc
ride that thing

i agree, these tires are exceptional, possibly a step above the new Bontrager H2 HardCase, time and experience will tell.
do the Whizzers run some type of DOT tire ? i think they are motorcycles in my state, but i don't know how far they push the regulations on them.
otherwise you would need to look in the 21" class of tires and rims for something you could make fit, then lace it onto something like augi's moped hubs.
are you planning on doing over 60mph ? it's been reported that at "the flats" if you plan to exceed 60mph you have to have DOT rated tires.

PS go somewhere like www.rockymountainatvmc.com and search dirt bike wheels and dual sport tires. you might have to run a front tire on the back for fit but it will far exceed your likely requirements. some of these coupled to great hubs, esp. those with drum brakes (like augi's ) would be killer.
you may have just helped me get around the $700 a pair mags i've been considering THANKS !!

boy, someone really likes my hubs...search ebay, detonator', i've seen complete '82 AMF moped hubs there. they're heavy tho, be warned.
far as i know, noone offering a "complete" MB, including Whizzer, has DOT tires. far as i know, there's no such animal yet.
anyways...dan wright, lead technical inspector for Utah Salt Flats Racing Association, never actually said he needed to see DOT specs...he asked for "speed-ratings" from the maker if anyone's gonna break-out at 60mph+...and he also mentioned that a serious professional racing effort might could convince a maker to do it, too. he would know, eh?
when stude & i were at the flats, a couple guys with the racer next door in the pits snidely remarked "so, this is really about advertising, isn't it?" in reply i pointed to the full-coverage "Lucas Oil" mural adorning their friend's trailer and said "you mean like that? then yeah, i guess it is. but all i care about is i'm not watching, i'm racing!"
i went exactly 32.4mph (tanaka 32cc) faster than either of those two guys
SPJ: this is just in reply to what's here right now...i don't know why you're looking for DOT ratings, but clue us in and we'll keep talking.

yes i do, those wheels are art in motion for the applicaion. in custom projects it's often difficult to keep some owners on track and achieve that totally homogenous outcome where each part anticipates and compliments the next.
you've done it with a persistance toward the "function dictating form" view.
others here have managed it too, you see it instantly when it's there.
about DOT tires, Pirelli, makes a 80/90 X 21 dualsport tire that is speed rated at 115mph.
this tire would be roughly 3.15" wide and 26.66" tall mounted.
one of the considerations of going this route is the weight of tires like this. depending on maker, exact size and tread type they can easily be 10#'s each. in the motorcycle app. this is not a concern but for a MB you will have to consider it more closely. because of the added mass, hubs, bearings, spokes and wheels are much more criticle. getting them rolling is going to take POWER, controlling the increased gyro effect is going to take a very good fork and axle, stopping them is going to take exceptional brakes.
it will be interesting to learn more about what prompted this. i see the whole thing as being doable, the MB that would require and support it will be something special.

If you absolutely insist on doing this, it's really not that difficult unless you insist on putting a motorcycle tire on a bicycle rim.
It's much easier to just find a suitable motorcycle tire, and then lace a motorcycle rim to a bicycle hub. Both motorcycle and bicycle wheels are available in 36-spokes, a 36H motorcycle rim is typically an off-the-shelf item. In the worst-case scenario you would need to order a plain (undrilled) motorcycle rim and have a shop drill the spoke holes for you (or you could do it yourself, if you feel lucky).
This does not escape one underlying problem however, which is the weight of the finished wheels. It is possible to mount a motorcycle tire on the rear rim of the Scwhinn OCC chopper bicycles for instance, but almost everyone who does comments on how much heavier the motorcycle tire is compared to the bicycle tire. A motorcycle rim is going to be much heavier also....

Hi folks, Sorry for the delay in getting back to this ,been away. The reason I inquired about DOT approved tires is that I'm in the process of applying for a title for my Whizzer. Title is required so that I might get a motorcycle liscense
plate. In Ohio where I am applying,as in many other states,a motorcycle liscense is required for any bike engine over 49cc. The state inspection officer that I've been working with suggested a list of Dot approved equipment (headlight,taillight,turn signals,mirror, and perhaps tires)that would be necessary to pass state inspection. I think my bike will pass unless I am required to find different tires. By the way, I currently have the Worksman Kevlar belt tire with the puncture reststant inner tubes. I'm confortable with these tires but it remains to be seen weather the state will find them acceptable. I'm in the midst of this process and will report at a later date on the outcome. I'm very appreciative of the information that the members of this forum have provided. Thanks again.
