platvis Posted June 21, 2018 Posted June 21, 2018 Hi Guys Does changing to say 28mm road tires from 23mm make much of a comfort difference? Cheers, PV

cadenceblur Posted June 21, 2018 Posted June 21, 2018 I went to a 25mm and I'm enjoying it. To my knowledge the 28mm are more popular for terrain similar to cobbles? I could be mistaken though. You might also need to check frame clearance
'Dale Posted June 21, 2018 Posted June 21, 2018 25c rocks and perfect for normal road useamazing the rolling experience from 23c if you wanna 28c, just make sure of tyre clearance
Cippo Posted June 21, 2018 Posted June 21, 2018 Depends as well what your inner rim diameter is. If you fit a wider tyre on a rim with narrow inner dimension it will have a mushroom effect. The wider the inner measurement the better a wider tyre will seat. Attached is the ERTO sizing chart.
Vetplant Posted June 21, 2018 Posted June 21, 2018 Running Schwalbe Pro Ones in the 25mm size on American Classic 30s, installed on the rim they actually measure out to be 27mm, rides very comfortably. Had to open up the brakes to clear the tyres but not other adjustments needed. Go for it

Super plush ride.
Spirog Posted June 22, 2018 Posted June 22, 2018 Tp get the real value of the wider tyre, drop your tyre pressure. I'm running 28mm tyres @ 6 Bar - 80 kg. It is comfy and grippy.

I used to run my 23mm tyres at 7+ Bar, being 94kg dry wieght. With the 25mm(27mm on the rim) I run them at 5Bar and they are smooth.
HdB Posted June 22, 2018 Posted June 22, 2018 Yep, I've also got 25mm tyres on American Classic Argents, which come out to just under 28mm. Super plush ride.Same setup here, 25mm Gp4000SIIs on Argents. It feels great, but on my 2008 Merida frame the rear tyre is a prayer away from touching the frame.
MintSauce Posted June 22, 2018 Posted June 22, 2018 As mentioned, do your homework on fit. I would assume that your LBS would be prepared to fit the tyres to your bike to see if they work and remove if not. As an example, I've been running 28 Conti Gatorskins for 2 years. Recently picked up 28 Conti GP4000s tyres. Was surprised to find the GPS4000s don't fit my fork, which is rated to accept 28s. Measured with a vernier caliper, the Gatorskin 28s in fact measure around 27mm while the GP4000s are 30mm on the same rim.
Zub Posted June 22, 2018 Posted June 22, 2018 I made the switch from 23mm to 25mm last season and will never ever look back. Front fork clearance is just about enough with some extra space at the rear. Actually thinking about going 28mm rear and 25mm front just out of curiosity...
Flowta Posted June 22, 2018 Posted June 22, 2018 Anybody got a 28mm lying about that I can check for clearance on a vintage frame? Pretty confident that 25 will clear
