Question: Well there is 2 answers to the max air pressure, does anybody really know what it is ?
Document: I ended up exchanging both tires at separate times because the side walls tore. I kept the air pressure well within tolerance but they just could not take it. The last straw with these tires was yesterday when the rear tire split again. It looks like I hit a piece of glass or something that hit the very edge of the puncture guard. The tire split vertically from the edge of the tread all the way down to the bead of the tire. Thankfully my puncture resistant tubes did not blow out.
These are good tires with nice tread. They installed easily enough and I've been riding them on my bike now for months. I believe the max PSI on these tires was around 80 or 85PSI, so make sure you have an air pump that can handle this range. Overall a good purchase and I have zero regrets.
Like my review of the Thorn Resistant Tubes, I was searching for a solution after having 2 flats in a week. Rather than settle for just a thorn resistant tube, I decided to go whole hog and buy a beefier tire as well. Thus far it works great. I would buy one again. I rated it only 4 stars because I haven't had it long. If anything changes, I will update my post.
I commute about 125 miles a week I tried heavier puncture resistant tubes to using plastic insert shields to reduce the number of flat tires over the years. None of them worked well until I used the Kenda Kourier K-shield tire. I love them for this reason. I normally get about 6 flats per year and this has been reduced to about 2 flats per year. This translate to one flat every 3300 miles (versus one flat every 1100 miles).
This is a really good tire, with better tread and color than what came on the bike originally. I'll buy it again if necessary.
Amazon sent each tire in a separate box, not folding the tire. I don't know how they do it. This is a big box. The tire was not scrunched up. I did not need tools to mount the tire, so easy! !
I bought these tires because I got flats riding through a dirt path one day and ended up walking my friggin Diamondback Edgewood back 2 miles.
After 2&1/2 years and nearly 2,000 miles - it was time for new rubber. My original tires on a 2008 Raleigh hybrid were neither these 700x40C tires or theKenda K192 Kourier Tire 700x35 Black Steel. Mine were 700x38C Kenda Kouriers. And after those 2&1/2 years, only ONE flat tire.
So, I plopped them on and I haven&#8217;t had any flats yet&#8230; I didn&#8217;t go through the same dirt path (cause, ya know, who wants to get flats on purpose? )&#8230; but I have put on about 40-50 miles since then and gone through other dirt paths and I didn&#8217;t get a flat.
Only expected 2-3k miles for tires at this price point and construction, so was pleasently surprised. Avg handling in wet or dry conditions.Plan on removing any debris stuck in the various grooves regularly and of course, avoid any road hazards/debris whenever possible. Use my bike daily and avg 30-40 miles per day. There are lighter, better handling or tougher, longer lasting tires but these Kenda Kourier tires are a decent/budget buy.
Answer: yes
