    FAtback/ Speedway Tires?

    A little bird just told me about some new tires coming out this year under the Fatback name, with a size slated between 4.0 and 4.8...
    I predict a faster rolling, high flotation option, with less aggressive tread than Bud/Lou.

    Will be nice to have another option, adding to the Specialized and Bontrager releases this year as well.

    I should neg rep you for being a tease, but I am a good mood from a 30 mile road ride, so I will let this slide.

    Me too. The pile of tires in my basement is impressive. There are at least a dozen different models in a variety of sizes adding up to about 30 pieces. For me it's because the tire can make or break the ride so I have a collection. When I travel I bring a box of tires so I can change out depending on what's needed for the the day.

    One would guess maybe they would be, seeing that they are Vee Rubber made.

    That's what I'm hoping, but a wider casing, custom tread, and sole distributor (guessing) might add a slight premium.

    This tire might be the ticket to running one of the new suspension forks with clown shoe rims. The Carver rep said in one of the threads that they fit BFL but it was tight... so this slightly narrower but still big Fatback tire gets

    Is it possible that this tire will still be over 4" on a Marge Lite?

    Either way put me down for a pair.

    Any word on carbon rims?

    If you look here:

    How Fat can we go? | Blog | Surly Bikes,

    You'll see that most tire casing widths grow 5-7 mm as you step up from 80 mm to 100 mm rims (Lou is an exception at 10 mm casing growth). Call the average 6 mm. That means every 10 mm increase in rim width yields roughly 3 mm in casing growth. So if the tire is really 4.25 inches on a 70 mm rim, then its width in mm on that rim is 108 mm (=4.25 *25.4). So you'd expect it to be 111 mm on a 80 mm rim and 117 on a 100 mm rim. That puts it somewhere between a Big Fat Larry and Bud/Lou. If so, it's my next tire purchase.
    --Peace

    That's cool thanks but still pushing for real life actual measurement atleast for a starting point. It kinda makes a difference if I want to stick with my 90's or go up to hundies.

    P.S. I do believe as far as what my resource was saying it should be pretty close to a .4.25 but I do know the kingpin is watching this thread so I'm just trying to pry some more info out of him. Oh and tubeless width as well

    Just wondering how you think that? The "spec" measurements are 4.2" / 4.7" / 4.8"

    I don't see how this 4.2" could be between BFL and Bud/Lou.

    Wow, did you even bother to read my post or look at the link? Take a look at the link and compare the tire widths at various rim sizes.

    This is why I'm trying to get it right from the horses mounth to bypass the armchair tire speculations. So far all I've gotten is one smart a$$ answer and one good edjucated guess (the later was appreciated btw)

    Haven't the 70mm/90mm UMA rims given similar tire widths to Surly 82/100 rims? I thought I read that somewhere.

    My experience yes and no at least for the 90mm/100mm. with the Umas set up tubeless they run pretty close to a hundie with a tube but with both set up with tubes there is a 3mm ish difference.

    Yes I read your post and I've seen the Surly specs. But if you take 3 tires at 4.2, 4.7, and 4.8 and put them on the same rim, the 4.2 isn't going to fall between the 4.7 and 4.8 width. Unless the tire manufacturer is bad at measuring or I am missing something?

    Or one of our AK friends could sneak over to their shop with a caliper and put end to this.

    FAtback/ Speedway Tires?

    So these tires are .2 wider than current vee rubber offerings So does vee rubber have a new casing or is it the knobbies bringing the width out to 4.2? I guess we will find out when released.

    From the article posted giving the tire info...it states that it's a Kevlar bead that is tubeless compatible.

    It is also my understanding that the Uma rims are designed to hold a tire bead a little tighter than other rims, and thus hold a tubeless setup better; correct?

    Now; is this tire designed with the Uma rims in mind; and if so, what does that mean? Seems like a natural course of action that they are.

    Again; if so, what will it mean for the non Uma rims?

    I suppose that will take a little time to pan out.
