2.8 inch tires on a Trek Rail.

[EMTB Rider]

Has anyone installed 2.8 inch tires on a Trek Rail. Thinking about bigger tires since I ride mostly chunky trails.

Yes. Magic Mary on the rear. I wouldn’t recommend it, just felt a bit vague. I’m actually running a 2.4 now and it’s much better.

2.4 on the back only @Doomanic ?

Will need new tyres soon and umming and arring on what to get. Longevity and all rounders needed if such a thing exists.

 

[Doomanic]

Yes. 2.4 rear and currently 2.6 front. Will be trying the new 2.4 MM on the front next.

What you got on the back, big Betty or something?

2.6 are nice but with 40mm rims - bontrager line pro 40 carbon Whole wheel looks like better and do better. (I did it because my weight)

So the answer to 2.8" seems to be "no".

I’d say my Rail 7 has more than enough clearance to run a 29x2.8” tire. I wouldn’t even try on rim with less than a 35mm id. On a 30mm rim 2.6” is perfect. TBH there isn’t many options in 2.8” for 29” wheels and the ones that are out there especially WTB are insanely heavy
