Vittoria Cross XG Pro, 60 PSI Minimum?
These came on my new bike and I will be the starting point for cross tires for me. Clincher 32's on Mavic Aksium wheels.
Tire sidewall says min 60psi max 90psi . Many people seem to have tire presure recomendations of 40-50 psi for clinchers depending on the course. Does anyone have any feedback on this combo at lower pressure than 60, and an outcome. I expect I will be higher than 40 (as I weight 200#), but 60 seems too high to be the minimum. I know getting out and riding will tell me the story but is there a reason for the 60 psi minimum that I should be concerning myself with? |
You should be fine. You'll see soon enough; if they're rolling off the rims in corners or you get pinch flats, you might want to switch.
I weigh 150 and ride light, and I've run Michelin Muds down in the 25 psi range without problems. |
Also, remember to use some talc or something similar on your tubes. This will help to avoid pinch flats.

I got a set of these last year, and I was skeptical about the high pressure rating as well, but I like to ride my tires a little harder than most. I tried once to run them down around 45 and when I did that it felt like they were going to roll off the rims when cornering hard, so back up to 60 they went. Might have been mental and I need to try again this year on one of my training rides, but that was during a pre-ride for a race, so wasn't going to mess around with it.

These came stock on my new bike and I've been riding them at 45-50 psi, I weigh ~170. I haven't felt like they were going to roll off the rim, I tried them at 60-65, but they were too harsh and I was sliding around a lot in soft stuff.
|
we're talking about the diamod tread vittorias, right? i raced one in the rear last year at ~35 psi, never had a flat or problem, and this season riding one in front at ~30-35 psi has not been a problem, either - no flats, no tires coming loose from the rim, anything.

Recommended pressures are always conservative.
|
Ok on my training ride this week I set them to about 50 and they felt good, so must have been a mental thing last year. Next weekend is the first race of the year so I will report back how they worked in the race.
|
I've run the XNs at 30psi and I believe they are the same casing, different tread.
|
Thanks everyone.
I have been riding them and using lower presures each time. I am at 45 rear 40 front and no problems yet. I think I only need some new brakepads and I am set for some races. |
