Tire popping fool!

I purchased a Fuji cross about 5 years ago and was just discouraged about all the tire changing every time, yes every time I rode so I left the sport. I would love to get back into cycling but need some tire advice. I'm 5'11 a stocky 270lb looking to reach 200lb in the distant future. The bike is set up with WTB Dual Duty700c/28 mm rims and Continental Sport Contact 28's. Any suggestions on rim or tire changes so I'm not blowing the front tire out every time I hit a small bump in the road. Thanks for any replies in advance, looking forward to loosing weight the fun way.

What PSI did you use before? Also, its good practice to fill the tires up before every time you ride. If properly inflated, and properly installed a 28c tire should be just fine.

270 ain't that big. Make sure the tire pressure is correct. Look on the sidewall of the tires for a MAX PRESSURE XX PSI label. Could be 75 psi, 90 psi, 100 psi, or other. Inflate your tires to that listed Max Tire Pressure before each ride. If you don't already have one, a floor pump with a guage is perfect for this task. You will be good to go.

If you are getting flats due to sharp objects puncturing the tire, that is a different matter. Puncture-resistant tires (with Kevlar) are great for addressing punctures. But if it is pressure-related, know your tires' psi and keep them inflated. Ride safe!

It sort of depends on what you mean. You should never be "blowing a tire out". If you're running the tire at too low of a pressure, as compared to your weight, you can get pinch flats on bumps, which is what the advice above is addressing. If you're actually having some sort of blow-out, you have some sort of mismatch between the tire and the rim, or a damaged rim, or damaged tire, or you're not getting it on right, or something. It might help to have a knowledgeable person look at the setup in the flesh, as opposed to reading the internet account. Problems due to low pressure or excess weight will normally show up on the rear tire, not the front.

I'm running about 220 lbs. My stoker is about 140 or so. So that's 360 lbs on our tandem, plus weight of the bike and stuff in the trunk bag. I use Gatorskin 32mm at 100 psi, and have never had a blowout or pinch flat with them.

BTW, if your bike has been sitting unused for 4-5 years, take it to a bike shop for service. They can help you with the tires too.

jwchef,

A cross bike should be able to take wider tires. The knobbies that came with my bike were prone to punctures, so I changed to Schwalbe Dureme Marathon touring tires, listed as 32-34 mm width. They have a "Vectran" Kevlar-like aramid belt, and I haven't had a flat in two years, and the wear on the treads is low (I don't know the mileage, but it's over 3000).

They only inflate to 80 lbs, so they don't have the speed of road-bike tires. We've suffered from "deferred maintenance" of our roads here, which has led to lots of deteriorated pavement.

I weigh 260. A guy in Florida named Etienne, he's French, sold me them for under $60/tire in 2011. He runs an online store for bike touring. I forget his company name, but I found it on Google.

These are excellent tires for heavier riders. Also, I use thick tubes. They're less prone to pinch-flatting when riding over bumpy surfaces.

I run these on my Fuji Cross bike:

Very comfy and still room for full fenders. The trick, as noted above, is correct inflation. This means inflating to max PSI using a gauge, not how firm the tire feels, to make sure you have them fully inflated. And you'll need to top them off at least once a week to make sure they stay at the right pressure. Thicker tubes will help and will also help the tire retian pressure longer.

Get a good floor pump that has a gauge on it.

Start with looking at 35c and larger tires. I've had good luck with Vittoria Randonneur Cross and Zafirro tires (these are relatively inexpensive). Have had really good results with Schwalbe Marathon XR, Duremes, Big Apples and Winters for Winter. The Schwalbe's are more expensive but tend to be worth it.

Thanks everybody for all the advice! I was using max psi before every ride for both tires. I think the first thing I will do is take it to the local bike shop to give it a tune up The local bike shop is 35 miles away, crazy. Between the bike shop and the great people on this site I should be back in the saddle soon. Thanks!

Youtube has great videos for bike repair. Maybe check out the mechanics subforum. Google is your friend. Stat riding much and a bike shop 35 miles away is going to be a hassle.

Right now, I'm riding Forte Strada-K tires from performance. 700x23 max psi @ 245 lbs. Cords started showing at I guess around 750 miles, but never had a flat. Maybe just the kevlar, I don't know. Previous tires I would guess I averaged a flat every 100 miles. For the price I paid ($15 + shipping) I really like them. My only issue is they are a pain in the a** to mount/dismount with my wheels. I keep a folding tire I was using as a backup on rides.
