Hi All,

I'm keen to fit some hybrid tyres and wheels to my road bike so I can go down a few un-paved roads on my way to work. Is this a good idea? It's a BTwin Triban 3 54' frame. IS there anything anyone can recommend?

Thanks for any help.

(first post - sorry if I've started this thread in the wrong place!)

Bicycle wheel rims, just like car wheel rims have a recommended range of tire widths that can fit on them. Rims that run 23c tires as standard can handle 25c and even 28c tires but anything larger than that is too big. Thats just the rims however and you need to consider tire clearance on the bicycle frame. Most road frames should be able to handle 25c but some high performance frames won't have the clearance for 28c.

You need to look carefully at your frame and see how much clearance you have.

I have a similar bike the triban 500, I think the frames are more or less the same; you're not going to be able to fit anything bigger than a slick 25mm tyre on to it.

Edit: I haven't actually tried with 28mm but i'm 95% sure they won't fit on there as 25mm are very tight.

Yea, Measure. the limit on a road bike is the frame clearance and the brake reach.

Want hybrid tires and drop bars , thats a Touring-Cross Bike.

Some road bikes like Trek Lemonds can fit up to 30 c tires. But hybrid tires? They simply don't have the clearance!

Get a gravel road/adventure or flat bar hybrid bike if you want to ride with wider tires.

I recently did the same thing on my road bike (check out the other thread in the gravel biking subforum). 28c is probably the most hybrid tire you can fit on there, but that depends on your fork, brakes, and rear frame (check the clearance between the tire and the seat tube too).

I settled on Schwalbe marathon tires as they supposedly have bulletproof lining. There were a few other recommendations in that thread.

Comes in 25c/28c versions. The bigger the better, use a caliper to check your clearances. I run 55/70 psi for 15% tire drop and so far so good. You may need to switch to bigger tubes too.

My bike is now pretty comfortable off-road. I can ride through brush and gravel pretty well. No-go on sand.

Looking at images of that bike on the web it doesn't look like it'll take a much bigger tire due to how close the regular tire is to the brake caliper already.
