Why Fat Tires Blow

Here's my thoughts. They're having such a bad effect on the way bikes and frames are built. Huge tires plus the short back end trend are making chainstays so wide they cant clear anything bigger than 25t without horrible alignment. Plus they feel sloppy and look almost as goofy as 9"+ bars. Basically, fat tires in my opinion are incredibly limiting to the creativity of bike builds. Thoughts?

What's your definition of a fat tyre? Are we talking about anything wider than 1.75" being fat or do you mean the new ultra fat tyres that are like 2.4"?

I think the original width that the oldschool tyres use is probably too narrow for street riding. Only recently have I seen tyres that I would call too wide. Personally I wouldn't ever want more than a 2.25" on the rear.

9" bars don't look goofy imho, but 11" does look strange to me.

BMX trends seem to get pushed to the very limit until a company comes out with something so extreme that everyone decides enough is enough and things start moving back the other way again. Wouldn't surprise me if we are close to or already at that limit for tyre width.

Fat is anything over the standard 2.25. There is no reason to ride over 2.3. Your right about the trends. Its so crazy. Heavy/light/back to heavy, small bars/big/getting smaller?, now tires. I think people are starting to realize they suck, and are mostly for looks. Give it a year or two.
All you have to do is look at what the pros ride. 8-9" bars. 2.10-2.3 tires is what the majority use.

I completely agree. Especially having the issues I did with chainline. There's no way I would've been able to fit a 28t sprocket on that frame, and I had to put a dimple in the chainstay just to get a decent chainline with 25t. The crank arms were super close to the chainstays too. I think most companies have realised this now and started to work out a way around it (the v2 of my old frame already has a dimple, and I think they used narrower diameter chainstays). It looks weird having wide stays and 2.1 tyres though haha

Yup i have a pair of tioga powerblocks folding 2.1s they weigh like 12-13 oz and feel amazing.

I like fat tires they're nice imo. My chain line on my bike is perfect with a 28t sprocket and my cult ak tires never rub(I have a fiend Reynolds v1 frame). I also think they look pretty cool with the added benefits of traction and cushioning on hard impacts. Down here in socal it's hard not to go to a skate park session and see anyone with 9" bars and below and a cassette and skinny tires 2.1-2.25 range.

Tldr: big tires are pretty cool

I've always rode 2.25 except for what's on my bike now and they're 2.10 and 2.20. I've never rode fat tires always wanted to though just never risked buying them and not liking them. As far as 9+ bars go they are far more comfy with me being 6'4"

fuck fat tires. they're heavy, slow, and you can't run brakes. I challenge everyone riding 2.stupid tires to have a few sessions on 1.85 tires and feel the difference. so much smoother faster and lightweight.

even when I rode street I rode 2.1 tires max. and even then i thought that was too big. 1.75-1.95 FOR LIFE

Yeah I'm pretty sure someone came out with 2.5" tires. Like enough is enough.

Damn wasn't expecting almost everyone to agree with me lmao

Tioga powerblocks are an under rated tire. The weight of a 1.95 but the grip of 2.10. They are perfect. If your grinding a lot, streetblocks, but they are quite a bit heavier. I love the tread design too.

The cult ak tyre is 2.6" inflated grin

I'm currently on 2.4 in the back (gonna go back down to 2.1"), with brakes, 25t sprocket and 13" cs, there's still a decent amount of clearance between the frame and tyre, and frame and cranks. Getting a 28t on there while maintaining the chainline might be tight tho. If tyres get any wider and chainstays keep getting shorter they'll have to compromise on clearance or we'll be riding 23t sprockets again. sick

To get my chain perfectly aligned on my fit benny i would have to put a dimple in my frame, and i really cant bring myself to do it. Im only running a 25t sproket. Shits just dumb. I think most kids running anything over 25/9 dont even use all that gearing. Going 5mph on a foot tall ledge with 28/9? I dont get it. Oh well.

Fat tires suck. I rode 2.3 fafs and my bike felt like shit. 2.1 or 2.2 maxxis folding tires, khes or Tiogas are where it's at. They're worth the money

Edit I agree 9 inch bars and bigger look silly

I think that fat tires have their place. If you are someone who rides stupid low psi than fat tires are a great way to stop getting pinch flats. I personally ride 15 psi in my front wheel (I know horrible on my bike but I don't need more people telling me this. It's my bike not yours) I have really bad wrists so this makes it really nice for landings. I don't go fast at much an personally don't have any problem gaining speed on these tires. I used to get flats constantly but after switching to a 2.4 I haven't gotten one flat. So at the end of the day they have their place but defiantly not for everybody.

I could never see needing to ride bigger than 2,2..and I agree that these trends definitely effect the way the bikes are designed. That is only bad in my eyes if they quit designing the models and specs I like....

I also don't think 9" bars look goofy. I actually think smaller bars look odd, especially if it is an adult riding them. No one around here has anything bigger than 9's so I have not seen the bigger ones in person to get a perspective. Hell, I think all the seats that are all the way down look ridiculous...but I am old. I KNOW that I get shit for my high up 80's seat position...I just don't care...

I ride 2.4s and while I like them, I have been planning to get 2.2s or 2.3s. I do agree, short chainstay + big tire + big sprocket sucks ass. I'm currently running a 30t sprocket on a 13.11 chainstay, and you probably can't fit a piece of paper in between the chainstay and sprocket. I'm eventually getting a frame with a 13.3 chainstay, and a 28t guarded so that should fix most of my problems. 2.3s probably wouldn't hurt either.

I completely agree on this one.

I'm also that someone who rides low pressures-it's just amazing on brunt landings or drops. I try to minimize as much energy and shock that goes into my body as possible, and I think fat tires and low pressures really do help.

I was horrified when AK's 2.5 tires were brought onto the market. Never in a million will you see me with those, let alone anything above 2.3" tires. I've found my happy place with 1.95" Maxxis tires.

I like a big tire in the front as it seems to lessen the impact a bit. I keep a small tire in the back but haven't had any alignment issues yet. I think 9" rise bars are the future because it allows riders to have an erect spine while riding. Check out old props videos and look how hunched over they are compared to Stevie Churchill or other modern day riders.

2.1 maxxis grifter on the rear and a 2.3 (inflated 2.25) grifter on the front. I like the wider front for foot jams but god damn do big tires slow you down.
