RogM Posted October 3, 2021 Share Guys Is there anyone in pmb or close that has 32 or 35 tyres on road bike rims? I would like to check if I have space between my brake calipers to fit wider tyres before I buy '91 Bridgestone Radac Cheers Rog Link to comment Share on other sites More sharing options...

JulienR Posted October 4, 2021 Share What size tyres do you have on now? you can also use a small allen key to move around the tyre and see how much clearance the frame has. Not perfect but it will give you a good sense. e.g. if you have a 28mm tyre and want to try a 32mm tyre, then use a 2mm allen key on each side. . .

Front is 23, 7mm passes comfortably, 8mm catches. Rear 25, 4mm easy fit, 5 catches at the top.. Cheers Link to comment Share on other sites More sharing options...
JulienR Posted October 4, 2021 Share So 32/34 will definitely not fit. 28mm could fit depending on the type of riding you do (i.e. not muddy) Link to comment Share on other sites More sharing options...

bikebloke Posted October 4, 2021 Share just remember the clearance between the tire and the back of the seatube where the FD clamp is that can often be tighter than the caliper clearance on an older road bike frame Link to comment Share on other sites More sharing options...
