Probably been covered alot, I did a search and found bits and pieces, but have a Q about Vred Fortezza Roads. I'm a non-racer, TCR2, and need to replace my Carbon Comps. I've considered going from 700X23 up to 25 with the Fortezzas. Any real benefit, or will the quality difference be a nice performance step up even in the same size? My understanding is that in general, a 25 may be more comfortable (although I haven't been feeling "uncomfortable"). Any thoughts appreciated.

I found that going from lower quality 25's last year to a higher quality 23 this seaon improved my ride and comfort considerably.I was riding on Conti Sport 25's that came with the bike.I switched to Conti GP 23's this year and it really made a world of difference.I think if you upgrade the tires to a better quality it should improve the ride quality without increasing the width.

I went from Conti Sport 1000 23s to 25 and the difference is noticable. Cornerer is more consistant and the edge is taken down on some of the smaller/sharper bumps. I am 200 so I should probably have been riding 25s or 28 the whole time anyway.

I went from 23's to 25's (I'd go to 28's but my frame won't allow it). I used Performance Forte (Panaracer), Conti
and IRCs. With the 25 you ride less pressure so your tires can absorb more "impact" from small objects. Makes a big difference when you are riding down a tar-chip surfaced road. (My friend with 20's was about to loose his fillings, I had no problem at all). Cornering is much better - I have yet to have the rear wheel hop on a fast sharp corner with the 25's. Overall it's more comfortable and better traction.

I weigh 160lbs. and ride about 100 psi rear & 90 psi front.

Also the quality of the tire will have an impact on it's performance - durometer of the rubber, casing design, tpi of casing, etc. As long as you go with a decent tire I think you'll be quite happy.

The second number refers to height, not width. Taller tires are wider though. A 25 would be more cushion assuming you need it. 23's have always worked fine for me.

I don't know about Vreds being a huge step up in quality from what you have. I assume you're talking about the tri-comps? They're a premium tire, but nothing stand out. Look for deals on them at ($33) and (UK site) for around $20, but postage is more.

I'm running some 25mm Fortezzas for the winter and notice the nice smooth ride they give. They're not as supple as my Veloflex Pave race / summer tires - but the added width and tread is worth it on the wet and gritty roads. They most probably won't feel any faster, but you'll most probably be spending less time at the side of the road.
