Weight and Tire Pressure Poll!(25 posts)

Weight and Tire Pressure Poll!SimpleGreen

How much do you weigh and what pressure do you run your tires?
Include your tire size as well.

153 pounds
105-110 pounds

I tend to get more cuts at pressures above 125 PSI.

210lb 125psig 700x25

I was running 120psig on 700x23 Conti's but was getting a lot of snake-bite pinch flats. It was so bad that I even checked the calibration on my floor pump. Moving up to 700x25's and 5 more psi worked for me.

I weigh the same as Jerry. I run 120-125 Conti GP 3000 700X23.
I change my rim tape each time I ad a new tire. I'd like to use a 700X25 on my rear rim, but my LBS doesn't stock them.

I always run them at the spec printed on the sidewall no matter what I weigh. Any lower and rolling resistance increases and the likelihood of pinch flats - any higher and you run the risk of a failure.

I always did too until I got the Super Sonics. The tires are rated at 145 psi and my Mavic Rims are rated at 140 psi. When I first put on the tires, I pumped them to 140 psi. The rear held but the front blew off the rim. I've been running them at 135 psi since and have had no trouble. I can tell after about 800 miles that these tires are wearing fast.

Huh - sounds like someone in the R & D dept. didn't do enough checking. Pretty typical in the bike industry. Could also be that your gauge is off? Having worked for one of the MTB shock mfr.s I know how cheaply made the gauges are.

I guess everyone needs to post tire and rim make and model and ensure that their gauges are well calibrated to draw any conclussions.

Do you run Super Sonics b/c you race?

Yes, that's it. Everyone show us that your gauges are calibrated!!!

No, I don't race. I was ordering some stuff from and needed tires. They had them for $26.00 ea. so I decided to give them a try because of the weight savings and to spred the shipping charges over more items. I like the feel but the rear is starting to get "boxey" after only 800 miles. I didn't even know when I ordered them that rims had a psi rating. I'll probably go back to GP's for everyday trainning but use the SS's for the group rides. I do like the feel of the SS's and I've had no "inconveniences" on the road. They would probably wear better if I could run them fully inflated.

Rough mountain roads so have
adopted the following ......

Conti 3000 Gp -reds 25mm
& full sized Conti tubes

weigh ~180 pounds
front @ ~ 95 psi
rear @ ~ 100 psi

no snake bites and
... very few flats

178 lbs, 100 psi, 700x20. And I never had a flat.Bruno S

Three sets of tires, different brands. The tires will not flat if I use 100 psi. I always make sure they are at 100 psi before every ride.
Never say never. : ) nmHap

It's a touring bike that I commute on daily. Tires are Avocet Kevlar Cross with additional Mr Tuffy liners. I don't care if I'm slow, I just want to get there without flatting. 95psi is the rated maximum, and that's what I pump. In addition to me, I'm carrying a rack & trunk on the back, and a low rider rack and small panniers on the front, so the whole load is at least 230.
