First 3 weeks - 2 flats - Jamie Roy

In the three weeks that I've owned my new Jamie Roy, I've had two flats, one on each tire. The first was when I rode past a construction site and hit some debris. The second was after I got to work, took the bike to the back and 3 hours later I see a flat.

Are stock Jamie Roy tires supposed to go out that often? I havn't even bought a presta-valve compatible pump so every time I get a flat I gotta take it to the shop. BTW I keep about 80-90 psi in the tires? Too low? Too high? I know nothing about road tires!!

Sounds like you need tougher tires. A search will turn up many threads on good commuting tires. Two that I like are the Conti Gator Skin and the Schawlbe Marathon Plus.

Does it matter how skinny the tires are? I was thinking I needed some teflon tires but I figured I was doing something wrong with the pressure or whatnot.

I think you mean Kevlar, and yes, it does matter how skinny the tires are for your frame.

Hah yeah my mistake. It's 330 over here and I'm working on my 4th beeer. How would skinnier tires benefit a bike?

Skinner tires wouldn't really benefit you, but a wider tire might. Keep in mind that there is a limit to how wide of tires your frame will fit.

A standard road tire is 23mm wide (in reality tire makers fudge the numbers a little so it could be 22mm or 24mm). For city riding I prefer a tire that is 28mm (in reality my Gator Skins are 26mm). They help to soak up some of the nastiness of potholes and cobblestones as compared to a 23mm tire. You need to find out how wide of a tire your frame can accept.

I'm sure someone will chime in and say how they love the skinniest tire possible and give you their take on tires as well.

I use airfreetires(.com) on my fixie and love it. There's a freedom involved in knowing that you'll never have to stop for a flat again. No pump, no patches, no late for work. Sheldon Brown poo-pooed them on his site, so you'll rarely, if ever, see a BF'er endorse them, but it looks to me like his review was done a long time ago, maybe before you could specify the "psi" of the tires, as you can now. I've been riding them all year now, and wouldn't switch back for anything. If interested in these tires you should note, go with a higher psi to get the feel you are used to.

i think ur psi is way low. look at the side of the tire, it tells u the max psi u need.
p.s it happens. i had gator skins and was getting a flat one a week for a month. bad luck i guess.

If you have a pump that's capable of 120psi, all you need is a little converter for schrader to presta. They cost $1. Never go back to the LBS that fixed the flats for you if they knew you didn't have a presta pump and didn't sell you one of these, they're either idiots or predators.

Road bike tires generally need to be pumped about every other day, sometimes they won't have gone down but generally you'll find they'll go down to about 90psi pretty quickly. Always inflate to the max, or at least to 110-115. The IRO probably doesn't ship with the greatest tires, but 2 flats in 3 weeks isn't a huge deal, especially if one was from big construction crap that no tire would have fended off and the other was probably a pinch flat from low pressure. Get a pump, tire levers, some spare tubes, and a patch kit, and if you're doing everything right and still flatting a lot, then look into new tires.

There's been a bit of talk about flat resistant tires on the forum recently with a lot of good advice as to what brand to use. I'll throw in my 2 cents. I've been using this setup for commuting with zero flats all year.

one of these in the front

and one of these in the rear coupled with any old 700c tire




I feel like having a good tire in the front that [to me] is as close to flat proof as possible is worth the money since the front takes forever to wear out. In the rear I just keep using free discarded road bike tires [I work at a LBS and they are plentiful] with a liner. Skid to your hears content without it costing you anything. When you wear a tire out just move your liner to the next candidate.

Well, I've just ordered a topeak morph so that solves my pumping problems. I didn't know that road tires needed to be maxed out every other day. Since I got it I've been leaving it in low to mid range pressure for weeks at a time.

I used to get atleast a flat a week, sometimes two. I got armadillo elites before the start of the season this year and still havent had a flat! I just put gatorskins on my new bike so i'll see how they compare.
How much do you weigh? that dictates a lot when talking about tire pressures. I weigh 185 and I run 110psi, if you are lighter you can get away with 100-105psi, heavier and you need to up your pressure.

I'm right around 140-150, I haven't weighed myself in a year but last time I checked I was 150 and I sure as hell haven't gained any weight.

How large are you stock tires? (Look on the sidewall-- it should say.) The size of the tire is also a determiner of proper inflation pressure. I personally hate real skinny tires (none of my local roads are accommodating enough). I run 32c tires, and keep them at about 75psi.

I had the EXACT same experience. Both tubes developed holes right around the valve seam after taking slight shocks (hopping onto a side walk and over train tracks respectively). I was running decent pressure (105-115) so I thought this might be due to a sharp edge on the valve hole in the rim, but many many miles later and I have not had the same problem using Michelin tubes.

I think the problem lies squarely on poor seam quality on the stock tubes. The stock tires have been fine, but I will be changing them out for winter.

This was the only thing I could complain about buying a complete bike from IRO, and since it was a $9 fix I couldn't really care less.

I had the exact same problem as well. The stock tubes that came with my Jamie Roy sucked! After two days of riding, the rear wheel got flat. Took the tube out and there was a tear at the valve seam. They really need to ship the bikes with better tubes!

As everyone is saying, flats are very common.

You need to always watch your tire pressure b/c when it's too low its flat. It's also terribly easy to get pinch flats and flats from glass. I moved on to the tire liners too and was problem free until I skidded thru a tire for the first time earlier and it popped the tube.

so.. I was commuting home from school tonight, 11 miles each way. I'm about 3 miles from home and a light rain starts falling. This feels nice because it is HOT and I'm almost home.. 2 miles from home, downpour.. it is a little less fun at this point. 1 mile from home, rear tire is feeling flat. Yup. flat. ****.

This was my road bike with fancy michilen race pro 2's, i hate those ****ing tires. my city bike gets ridden daily with crappy tires and rarely gets flatted..

Funny story...

I woke up one day to get to work, my bike had fallen over, didn't think it was a big deal. Picked it up, flat tire in the rear. Whipped out my spare tire, took about 30 min to swap out (first time switching tires). Got pumping and all I heard was leaking air. Took it to the shop next day and had Armadillo's put in in the rear only. Took it home along with a new spare tube, got on the bike, rode about a half mile and the front pops. Bad luck.

I'm thinking about switching out the front also, Armadillo's ok?

You've got enough opinions to write a book, but here's mine.
-At least 100 p.s.i. and be light over railroads. Tire's are designed to be ridden at higher pressure. I've noticed them to actually be MORE comfortable at higher p.s.i. and you'll have better handling, acceleration, etc.
-Armadillo's are the best. I ride them exclusively on my commuters. Two year's on my fixxie, no flats. 425 on my touring bike, no flats on both. Well, I got one flat on my fixxie ONCE, and it was where the tread was worn down to the red. And it was a piece of glass about a half inch across. I was impressed. That glass was motivated.
-Thirdly, on my Jamie Roy I could fit full reach-around fenders with 32c knobby tires, I bet I could have fit up to 38 with fenders, and maybe 40s w/o fenders. That's DAMN huge.

I can't stand large, knobby tires though. Ever since I switched to thinner tires, I've been stuck on them. I'm gunna switch out the front tire with an Armadillo and pick up a spare tube and call it a day.

I'm another rider with the same Jamie Roy flats. The front and the rear flats were each in the same position about a centimeter from the valve stems. Whoever installed all the tires on the Jamie Roys probably put the tube on the rim, tightened the valve stem nut, then installed the tire which is why we all got pinch flats at the valve stem area within the first 50 miles. I like my Iro, but they obviously had a poor tire mechanic and it would have been good public relations to replace all our flatted tubes.
