Wide tires on a Sirrus?

Has anyone put wide tires on a Sirrus? Wider than 37?

I'd like 40 rear, 35 front, oh, and disc brakes, and a 36 spoke rear.

Is there also room for fenders with those wider tires?

I have the carbon LTD model, and they would not even come close to fit mine. 28's maybe max, it is the same compact frame, as one of there road bikes.

theres a bunch of different sirrus frames. my globe vienna is a 2010 base model sirrus frame, it came with 35 and probably fits 40, but i put fenders and 32 on it.

I was just looking at the Sirrus and had my LBS throw on some 38s just to show me that they would work. That front fork has a good bit of clearance, and the 38s fit with plenty of room to spare for fenders. Just from looking at how the 38s fit, 40s would be fine. The point at which I would start to think maybe things wouldn't fit would be like a 45.

See if your LBS will try fitting a tire the size you'd like just to test the fit if you want to really up your confirmation of the fit.

Just wondering why you'd put 40 rear and 35 front. I'd imagine the wider tyre at the front would give more control and traction.

I can't speak to what Wanderer intends, but I've seen people say they want a winder tire on the rear if they plan on carrying some weight, like on panniers and such, but they don't necessarily want to go that wide on the front.

Did you do this with the stock rims, or change the rims? What year was this Sirrus?

I tried to look up a picture to illustrate the width of the 2012 and 2013 sirrus forks (elite and below, at least, anyway) and couldn't find one, but the fork in the 2012 and 2013 elite is quite a different shape. It is much more like an inverted U versus an inverted V.

When the LBS put on the 38s, there was more clearance left on the Surrus than there was on my Jamis Coda with 32s, and that Coda fits 35s.

Would love to know what kind of Sirrus Wanderer is looking at!

I'm sure your right, there are like 7 different models. I happen to have a 2013 catalog, The least expensive model is just called the (Sirrus) it comes with 700 x 32c stock and has fender mounts. All other 6 models come with 28's or smaller, and make no mention of fender mounts. The models go : Sirrus, Sport, Comp, Elite, Elite with disc, Pro, LTD..

My 2012 Sirrus base model has 35's up front with fenders. Can't speak to your rear wheel question, though.

I had a lot of different sizes to play with, and found that the 35 on the front gave me quicker and more precise steering, without sacrificing ride quality. And that the 40 gave me much more comfort on the rear, without sacrificing handling. It's now my sizing of choice on my hybrid. It came OEM, with 45s.

The Globe Work looks like a base Sirrus with modified geometry - more clearance and a little longer wheelbase. It comes standard with 38's and fenders. Betcha it would easily take 40's with fenders.

Deja vu, indeed. If you want wide, er fat tires - look for a bike that will accept the biggest tires available on the market.

The Surly Cross Check and early 90s MTBs and hybrids will accept fat tires. The only limiting factor is whether the rear stay will allow them.
