I've been riding on Maxxis Refuse's and I really like them, but I just wanna try out riding on a higher pressure (Refuse are 120psi). So I'd just like to hear some of your recommendations. My wheels set are Velocity Deep V's. I'm a 225lbs rider also, if that helps any. Thanks.

What about Vredestein Fortezza? They will take 145psi and are a handmade tire. I use 'em on my track bike and have no experience with them on the road.

Vreds are about the only thing I use in clincher. Great tires.........................don't listen to the "rolling resistance vs psi" crap. At your weight you should be running slightly higher psi.

I run about as much psi as I weigh in pounds :blush2:

Sheesh... those look nice but $55 a tire is a bit more than I want to spend right now. The max i'd like to spend on a set is $80-90.

Somehow I don't think "higher pressure" and inexpensive go together. Not when my arse is at stake anyway.

The overused expression "Light-strong-cheap; pick any two" kinda fits this situation.

Here, I did the work for ya -

Well, I was looking on Maxxis' site and they have the Xenith Equipe Legere, 145 psi, priced at $45. Obviously they aren't hand made... but thats not a concern/care of mine.

Higher pressure adversely affects traction, comfort, tire wear, and handling. You would do better to look at wider tires, rather than higher pressure ratings. A number of rim manufacturers do not recommend running such high pressures due to the ability of the sidewalls to handle the forces.

Kerry Irons has said it all except....
higher tire pressure also decreases the rolling resistance of the tire. At higher pressures the tire casing does not deform to small imperfections in the road and instead bounces, this slows you down.

Typo? - "higher tire pressure also decreases the rolling resistance of the tire." I think you meant increases. - TF

Don't you just hate it when reality gets in the way of what you want to believe? Higher pressure makes you slower. - TF

Reality doesn't make the uninformed buy your tire, but recommending bizarre operating pressures apparently does.

Actually the new Vredi Tri-Comps are rated at 175 psi.!!!!
I own a pair. Rim manufacture will sometimes post a Max. pressure for their rim.
You should check that out first. My rims are good for 135psi. for a 23mm tire.

You can damage a rim due to using higher then rated pressures.

You didn't mention tire size, but for you size, I hope you are using 25mm tires. That will d more for you than increasing the pressure. If you can fit them, use 27mm.

I didn't mention that I'm a tall 225lbs. I'm 6'3 and have a 34/36in waist. I'm kinda thin it's my.. .ya know... "rear" that gives me a bigger waiste.

But the Maxxis I have now are 700x23.

When they are at max pressure there is very little to no sag in the tire.

Two edged sword:
1) You'll blow away the competition
2) They'll blow you away if you get a blowout or flat.

Typo? - "higher tire pressure also decreases the rolling resistance of the tire." I think you meant increases. - TF

Well, technically, rolling resistance does decrease with increasing pressure; however, on non-smooth surfaces energy losses from impulses that are not coincident and in the same direction as the direction of travel also increase with pressure. The net effect, though, is much like decreasing crr. Those additional losses just don't fit the definition of crr.

Where in the power equation does it show up? - TF

They're not what I'd class as a usable (for normal riding) road tire. I have some and they're a miniscule 162 grams (23mm width) on my scale. They don't have a good flat-free road reputation but I've used 'em on an indoor board track for 3 years and they're great.

First, I shoulda paid more attention to what I typed. What I meant to say was that "The net effect, though, is much like increasing crr."

I'm not sure what you mean when you ask where it shows up in the power equation. Rolling resistance varies linearly with velocity as does the losses from over inflated tires bouncing off of road irregularities.

When I said that these losses were technically not rolling resistance losses, I only mean that they didn't fit the definition of rolling resistance wherein losses are the result of hysteresis in the tire carcass.

I weigh about the same as you. I just put on a set of Hutchinson Fusion2's. I only have 4 rides on them so far; so I don't know how long term durability is. Price Point had (may still have) them for $20 each. They are rated at 125psi max. I am running them 105 f, 110 r and they have been perfect so far. No problems with pinch flatting at those pressures. I may drop the pressures 5lbs front and rear just to see how they feel.
