When I bought my hybrid it came with 700x37 tyres. I need to get some new ones, and as I'm doing more road riding than anything else. Can I fit 700x28 road tyres on the same rims?
Hi,
You can but it is probably not a good idea. For most fatter tyres are better,
more comfortable, last longer, go faster and resist punctures better.
rgds, sreten.
Define "better". I went from 32c (Vredestein Perfect Max) to 42c (Continental Comfort Contact, then Touring Plus) with little decrease in speed (if any) and a massive improvement in comfort and grip.I'm certainly no seasoned pro and I'm sure Sreten has reasons for making this suggestion, but I can't help but think that "for most, fatter tyres are better" might not be entirely on point.
These are worth reading on the topic;

I have 23c on my "quick bike", because that's all I could get in Krylion Carbons. I prefer 25s, and if they'd fit, I'd ride on 28s.
I've not noticed any difference. I've p*ed both Comfort Contact, and Touring Plus, in both cases in circumstances I doubt a thinner tyre would have stood up to either (6" nail, 6" phillips head screw) so it's probably not fair to draw conclusions either way. I think Grant, from Rivendell, reckons a big, lower pressure tyre is kinder to your wheels (more cushioning, so less stress through bumps &c).Would you encounter any reduction in durability following the findings in those articles do you think?
Continental GP4000 SII - the difference between 23 and 25c is 20 grams. (205g, 225g). 28c adds 55g (260g)I am a big fan of the slightly larger tyre ie 25 v 23 but another thing to consider is the weight of the tyre, once up to speed a heavier bigger tyre is more comfortable & rolls just as well as the lighter tyre, but the lighter weight tyre will accelerate quicker,

In the Comfort Contact, going from 37c to 42c adds 70 grams. (600g, 670g). (All weights from Continental's website).
