I picked up a set of these tires today with my new races wheels (08 Mavic SLs). This is my first time using these tires and I noticed Vredestein lists the tire can hold up to 175 psi!! I have always ran my tires at 110 to 120 psi, would it be wise for me to run these tires at a higher psi?

FYI: I weigh 145 to 150 lbs.

Thanks for you input

probably not... the tire can handle that, but not most rims. every rim has a different max psi it can hold before the bead of the tire will blow off, to put it uneloquently.

they arent bad tires. well for a few hundred miles anyways, after that i started to get TONS of flats. you are a lot lighter than i am though, so i hope you have better luck than i did.

A gal that rides with us runs them at 170 psi on Campy Eurus wheels without trouble. I have used them and never go above 140. At the higher pressure the ride is too firm. Never had any issues at 140 or below but never put them on an indoor trainer. Ruined a tire in one session, the thing just kind of melted and I don't really know what happend but it was 60 bucks down the drain.

Interesting...

I've been on Tri-Comps exclusively for three years. Two flats, total. About 25,000 miles. I do about 1,500 miles on a rear before switching.

I love them.

I've got about 1000 miles on a pair and they're holding up pretty well. I never run them anywhere near 175 (the Ksyrium Elite rims I run them on have a max rating of 138 psi). I've played around with it a bit but mostly run 110 front and 120 rear.

I've been using Fortezza's for two year and love them. Bought them initially for the high PSI, and run them at 140 back/ 120 front, but I'm 225 pounds. Can't imagine you'd want to run them that high at your weight.

TriComps are great. They're not bulletproof but the number of flats I got on them while commuting on them for a couple of months (my commuter bike was in the shop that long, yes) was tiny (a couple of slow leaks from sharp glass).

I don't know why anyone would ride with those kinds of high pressures outside of a perfectly smooth track setting. Tires need to have a little give on a real road or a lot of energy is being wasted going over bumps big, small and invisible. 120psi sounds like too much for a 150lb rider on 23mm tires, let alone 170+ (and yes, rims likely can't handle it anyway).

damn, maybe i got a bad set then because i cant seem to go more than 100 miles without getting a flat.

Run all my tyres at 140 Psi and few problems with flats. Only problem I found with the fortezias was a short life- 600 miles and the rear tyre took a definite flat edge to it. and the front was showing a flat tread. Took the rear off and it was paper thin-

Wasn't too happy with the life of the tyre and the next tyre was Pro Race 2's and 2,000 miles on them so far and no flats and no flat showing on the tyre either.

The only good Vredestein tire is the cheap Ricorso. The others cost too much and don't last. I wouldn't worry too much about running 140 PSI. Stick with 100-110 and you will have a more comfortable ride.

The 25C gatorksin by continental is a much better riding tire for comfort and supple road feel. I think the Vredesteins are no different than the cheapest multi colored tires on the market. They have lots of advertising hype.

Vredestein Fortezza TriComp are a great set of tires and yes you can run them at a higher than normal PSI without exp any problems. Well that's if your current rims can deal with a hi psi inflated tire. I think if you have the 2008 version of these tires Vredestein was recommending 145psi range as the way to go.So try not to go over 145 on the newer versions.

I run mine around the 130psi front 140psi back range. I’m floating at the 155-160 weight range...
So far my wheels have held up pretty well with 0 flats and about 2200 miles on them. Unfortunately I am about to retire these puppies because last time I was out on my bike I ended up getting a hand full of deep slices in the front and rear. I could not avoid riding through a ton of glass that was left scattered across the road from a car wreck that must have happened earlier in the day or on the previous day before I set out to ride.
San Francisco tends to have the worst street clean up and maintenance program in the US. This city really sucks at cleaning up the roads after a car wrecks and streets are full of potholes...I swear it feels like I’m cycling in a third world country sometimes .
Anyway I will be switching to a set of Vittoria Open Pave EVO CG for the remainder of the winter season then I'll go back to Vredestein Fortezza TriComp in the summer.

Thanks for the input guys.
