Goldentyre GT216 "Fatty" vs "Chubby"

[Horgh]

Hey all,

I've been running the GT "Fatty" for some time and overall I really like it, but it does tend to catch the sides of ruts for me. I know a lot of guys love the "Fatty", but I wonder if it may be partially due to GT's rubber compound and tread design. So, GT also makes the "Chubby", which is basically the same tire but in a traditional 90/90 size. In theory, you would get the same rubber and tread pattern but without the thicker profile.

Have any of you ran them back to back? Or has anyone even tried the "Chubby"?

Thanks!

What pressure r u running in the fatty? I noticed less than 10.5psi or so it got squirrely

R u driving off the front or rear tire? I noticed the fatty responded well to more front pressure.

FWIW

All I "used" to run was the 90/90. And I still would had I not discoved the Hoosier tire.... 

[SteveThe Snakes]

90/90 is less clumsy. 

[Bob Walters]

I have run both back-back and I prefer the chubby (90/90) profile by some margin. It steers more precisely, retains much of the fatty ride quality, and doesn't climb out of ruts as much. If I was on sand I might feel otherwise.

I’m running the fatty and love it. Just recently spooned on the gen6 fatty, which is supposed to address the rut issue.

I think my "fatty" is the 6th generation, but maybe not. I'm running it with Tubliss at 9PSI usually. I think I'll try the "chubby" next then, although the "fatty" is not really wearing down much, so who knows when that may be.

Which Hoosier tire?

Skip the 80/100. Some how I bought one. I find it to be too vague and wandery. Also claws up the side of ruts way too well. Sketchy.

Yeah, the 80/100 is the "razor blade", I wasn't going to go that skinny.

Which Hoosier tire?

Our parts dept started carrying that tire, it seems to be a good Mx tire. Super light, rubber seems hard, which is good depending on soil.But I take it you haven’t switched to Mx, and it works great off road/trails for you?

I tried one GT fatty and was not a big fan of it climbing out of ruts, I have had a chubby for the 90/90 ever since and have blown my wad on a w of them, so to speak. Hard to beat the fatty for bump compliance though, nothing compares on roots and rocks. 

On a side note I ran the fatty at 12psi, the importer is local and told me the fatty is better at 15.

I've ran it at our local MX track but its predominantly sand so any decent tire seems to work. But yes, about 20-30hrs offroad and it's been the single best tire I've used. I don't really value durability over performance so I can justify any additional wear. 

I've been running GoldenTyres, especially the front for 8yrs now with about a 6 month stint where I couldnt due to supply. Back then, all you could get was the 100s as the 90/90 didn't exist. When I switched to Yamahas the 100 was perfect due to the way the front end felt on the Yamaha 4ts. But when I switched to the KTMs the 100 made the bike slow to turn and give it a sense of vagueness that I couldn't mesh with. I went to the 80 series but as other mentioned, it felt like a pizza cutter and the smaller knob profile shedded knobs quickly. Around 2016/17 is when I was able to get in the 90/90 and it was what I have stuck with since. Not generally the best, but better then most and had great durability (though I don't value it as much).

Last year I ordered a front and rear Hoosier. The front was phenomenal but the rear was done in one 5hr event which I was literally just running a chase program where I was just helping riders, not actually racing. I have noticed the Hoosier front is crack everywhere but not sure if it's due to lower pressure, or that it's now 6 month old? Or maybe a combo of both? I have 3 new fronts in my garage ready to be mounted but haven't had the weather to justify a change over yet.

Well next front I need I think I will give it a shot then at least. The rubber seems pretty hard, so maybe that and time it’s been on the bike makes it crack? How’s it on wet rock/root?

Phenomenal. The conditions you describe where I first tested the tire, for over 5hrs that day... Was like I was riding in heaven! 

[Horgh]

Pardon the stupid question, but how does a hard rubber compound do so well on rocks and roots?

Have you run them with mousses?

[jrodicus100]

It’s not a drive tire, so it’s is less about the friction from the compound, and more about bump absorption and lack of deflection from the carcass.

You still need grip on rocks and roots. Compound makes a big difference in a front tire.

I wouldn’t have expected that from my initial impressions. Well, next tire I buy, I will try that one and give it my best!
