I just switched out my stock tires for some new kenda 270's. The stock tire pressure was 22 psi front, 22-25 psi rear, depending on load.

Should I use the same with the Kendas for road riding? The max. pressure on the side of the kendas is a bit higher (up to 40 psi).

thanks

 

That should be fine.

 

22psi in the front and 24 psi in the rear tires is what I run on my Kenda K270's tires. Last set of K270's lasted me 5,500 miles and still could go further for street use, but not too well for off-road use. I use the sizes 3.00x21 and 4.50x18. The 3.00x21 is a 4ply, B load range. While the 4.50x18 is a 6 ply, C load range with a 50 PSI max rating.

 

+1 the above. as a rule, anything with a smaller **** or **** like traction you will want a heavier pressure than a more street like tire needs because otherwise the ***** tend to fold under breaking and wear badly

 

I max both front and rear out on the pressure, one because I......uuuuuummmmm ok I'm huge!,...two because I might carry even more weight, and three, I refuse to ever get a flat tire because of a wheel spin on the rim. I just did 350 miles off road and I ran 25 front and back, and I still felt a few of the rocks on the rim, so I'm just saying.

 

the 3.00 front has a stiffer sidewall than the 3.25 so can be run with a little less psi

the 4.50 is a very tall tire for it's size so could be run a little lower without ******* out, taller than the 130/80 which is closer to the stock size

 

Thanks for the replies...I'm 160 lbs, so I will continue with 22 psi up front, and 24/25 rear, for road riding. I was concerned that these pressures were too soft for the road, but I guess I'm thinking too much.

cheers

 

I dont know guys.....I don't know how you can run in the woods with those pressures. I run 15 max under the rockiest conditions (Im running cheaper Metzlers that are DOT approved - forgot the name). Anything higher and you feel every rock right through the handlebars. Have mostly rocks in the NE - A few thousand mikes between both bikes - one flat (many years ago).

Gone down hills that dead ended then couldn't make it back up, aired down the tires and made it. 12 is the lowest I trust without rimlocks, 15 is a good number off road for me too dklogic. But it really all depends on how hard or stiff the sidewall is.

since the post is about 270's, one thing you'll notice is the howl on the pavement. Nothing wrong with that? loud tires save lives,, right?. But you will notice as the 270 tread wears flat, or lays flatter because of low pressures they will make noticable more noise.

 

I usually take mine down to approx 15 for offroading with no luggage. Use a CO2 kit to take it back up to 25ish once I get back to the pavement.
