[RBW] Re: Rambouillet/etc owners fat tire advice
My Road Standard currently wears nominal 32 mm Vittoria Randonneur Hypers. On Velocity A23 rims they measure a good 34 mm wide. They shouldn't fit under short reach brakes, but they do. I weigh about 180, and don't carry significant loads on that bike. I can run as low as 60 front, 70 rear which is what I used yesterday and today. Lower than that starts to feel too squishy and vague. Optimum for me might be 65/75. The bike does handle a bit better with 28's, and after the next bike shuffle it will wind up going back to 28 mm Rubino's.

[RBW] Re: Rambouillet/etc owners fat tire advice
Back when I weight 168 pounds I could ride 23mm tires at 70 psi on smooth asphalt. these days ( 92 pounds heavier) I ride a 35mm at 80 psi and a 38mm at 70psi. 32's require 90+psi and are annoyingly buzzy (for me) on local chip seal roads.so I went to the 35's at 80 psi which is my personal lower limit. I think lighter riders can get away with more and also less pressure. Lets face it, high pressure narrow tires are faster on smooth surfaces and light riders can ride them more comfortably and safely than the rest of us. At your weight a 28mm tire is fine at whatever pressure the tire performs best at on the surfaces you ride on.

I try to keep my 32-622 Supremes at 60 psi in front and 80 rear. With my 170 lbs and ~ 10 lbs of gear the ride gets sluggish when I start to lose pressure. More that that feels harsh.

I'm with Peter. I weigh 205 lbs, my Rambouillet rides on Kojaks (which measure 32 mm) pumped up to60 front, 80 to 85 rear. Comfy front, zippy rear, it's groovy.

Hmmn, I'm baffled by your comments. I'm 6'1", 200, and I have 33's on my Ram. I drank deeply of the Kool Aid, and tried them at low pressure, hated it, the bike felt like a slug, and I promptly notched 'em up, five pounds at a time, until I got to 90, where the bike came back to life for me. (I know, it's all in my mind, and they're actually running vastly slower than they would if I kept them at, say, 65. That's OK -- I can use the handicap.) Even as high-pressure-oriented as I am, at your weight and pressures I don't know how a 32 could be feeling "bouncy". ~Peter On Thursday, June 7, 2012 4:09:18 PM UTC-7, JL wrote: > > Hello all, > > I might just be the kind of person that finds a happy mid zone in the > 700x28c tire as I can't seem to enjoy riding my rambouillet with anything > larger.
