Hello,

My name is Robb. Live in Grand Rapids, Michigan.I'm 6'1" tall and weigh about 225 pounds.

I have a Schwinn 5 speed townie, just for wandering around the city, not racing. The tires are wide. I'm pretty sure they are "tube-type" tires.

I can fill the tires to the maximum stated pressure, and the back tire still bulges where it meets the pavement. I know that I work a lot harder peddling than I should just because of the tire profile when riding.

People take one look at that tire back tire and warn me that it's going flat. Little do they know it's at max pressure. I'm getting real tired of riding this way..:mad2:

Do you bike experts have any advice for me other than lose weight? LOL

What options do I have?

Are there large diameter, wide tires or tubes available that can take a higher pressure? If so, where do I buy such tires? What do I ask for?

Can I over-inflate the tires I have now so they ride right but won't blow out as I'm riding?

Thanks for your help.

Robb

maybe your "Tube-type" tires are old as crap and you should go buy some new "tube-type" tires to replace them with. Maybe have the shop replace the tires.

losing some weight wouldn't hurt either. only kidding.

First off, fix your typing font.


2nd off, depending on the size tire, you can pick a different tire with a higher max pressure. Do not over inflate the tire, this could cause a bead to blow off at the most inopportune time.

Tubes don't dictate how high the pressure can go, only the tire.

Typing font? What, too big?

Fix my typing font. What, in your opinion, is wrong with my typing font? I assume you think it's too big, huh? Well let me tell you why I use a big font.

I'm 60 years old. When you're 60, you'll find that it's difficult reading small type. This is normal and VERY predictable; so predictable, in fact, that there's a formula for figuring out what strength reading glasses a person will need as s/he gets older.

The formula is Age-32 then divided by 10. So, for example, a 45 year old person with otherwise "normal vision", by the formula,

45-32= 13
13/10= 1.3

will need either a 1.25 or 1.50 strength reading glasses. I'd recommend getting the stronger of the two since that person will eventually need it

If you care, I'll tell you why this happens IN EVERY ADULT WORLDWIDE WITHOUT EXCEPTION.

Robb :thumbsup:

Robb,

First off, welcome.

Second, don't listen to people like pitted. Rumor has it he's a troll who moonlights as a poster-child for retroactive abortion...only kidding

Third, it sound like you should consider replacing the rear tube and possibly the tire as well. On the side of the tire, there should be a recommended range for the pressure. Try inflating the tire to the maximum recommended pressure. If the bike still rides "flat" the problem is with the tube, or the tire and tube, not with your weight.

abortion is the answer opus, how many times do i have to state this crap on the internet.

I kind of like the big font, hell Im 38 years younger than you too.

Get new tires and tubes.

The real question is .... how the hell did you read the tire info if you cant read size 12 font on a bright computer screen.

Read the tire info? How do you think I read the info? . . . .braille ? I wore my reading glasses, smarty.

Just wait until you're 60. You'll not only understand what I'm talkin' 'bout, but you'll need 'em too.

This natural occurring phenomenon CAN be avoided, however, by replacing the lens in each of your eyes with a synthetic lens...

I hear that'll set you back AT LEAST $6,000 per eye. Plus, someone cuts your eyeballs open to do it.

I said thanks anyway.

I weigh 200+ , use 700x25 tires 100 lbs psi.

P.S. I'm 67.

 

[Peanya]

The tire should compress a bit, that is normal. By townie, i'm guessing your tires are between 1&1/2" and 2&1/2". At 60psi, it will be more than adequate to support your weight. Unless your tires are very old, just don't worry and keep riding.

Hello,

My name is Robb. I'm near-sighted.

Fixed.

tip:
if you increase the font size in your browser, you will be able to read everybody's responses at a size that's comfortable for you without blinding the rest of us. (try holding down "control" while wheeling your mouse forwards/backwards)

 

[freethinker]

Your guage reading is off maybe? You might check your pressure using a different one. Your tire shouldn't look like it's going flat when it's at max pressure.

 

[roscoe]

what's the max pressure according to the sidewall?

From being around the Grand Rapids area myself, there are plenty of LBS that are all great and would be glad to help you out if you would go into one. If you would like I can pm you a list of shops in GR
