Vintage Frame Tire Fitment
I am building a 2001 Litespeed Classic frame. Factory it came with 700x23. I would like larger tires but am unsure of the max size that would fit. I imagine 700x25 would fit OK but would like a little bigger if possible. Im hooked on the fat tires that came on my Trek SLR !!
I am using Dura Ace 9100 rim brakes and plan on getting a set of Dura Ace C40 wheels. I know I can't go big with this bike but am seeking ideas for options. Thanks in advance. |
If your frame is anything like mine ('96 Catalyst, 2006 Tuscany) anything bigger than 700-23 is iffy and bigger than 700-25 is likely impossible. Depending on the fork you have it's likely to be equally the limiter.

Real simple... Measure.
Place wheels into frame, measure your clearance from the rim. Measure width, measure from rim to brake bridge in MM. That will give you an idea on the largest tires you can run. Give yourself 2mm in clearance for safety (If you measure 29mm from rim to bridge, (29-2=27) so for safety go with a 25mm tire. You sizes are 700x23, 700x25, 700x28, 700x30, 700x33. I wouldn't expect you to need much over that on a Litespeed. If you do, you probably need to reevaluate frame selection. |
Even easier is to try a wider tire and see if it fits. Since tire labels are not measurements and rim internal widths effect tire profile one can't really use measurements as the final word. Shops I have worked in will allow a customer to test fit a tire to see what, in real life with the real rims and frame/brakes, will fit with what clearances. When dealing with tires and it comes down to a couple of mm's only a true trial counts. Andy

It's probably similar. The fork is modern tho and is sometimes used for gravel bikes so it will be fine. I may put the 700x23 wheelset from my other Trek on just to see what it looks like.

Switch to tubulars. A 23mm tubular will ride like a 28mm clincher, only better.

I have a 2004 Litespeed Classic with 700-25 Continental GP5000. They fit with no problem at all. I can’t speak about any other brand of tire because I’ve never tried any other tire.
