i am buying a set of hankook dyna pro mt's. my question is should i sipe the center lugs? i live in michigan so snow and ice is a problem of course. what are your opinions on siping.

I would sipe the outer blocks if your running the air pressure on the low side. Just remember, the siping will open up as you put miles on, so sipe a little drive some see how it does, add to it if needed, so they dont start chunking.

If you drive logging roads at all avoid siping like the plague. If you drive mainly city streets and snowy/icy conditions they work great.

my parents live in the mountains in northern idaho, and his MT's are siped on all his rigs, and traction is great.


just curious, why would not not want to sipe if you drive on logging roads?

I went through two sets of tires on my truck both lasted just under 30k each set due to shredding the tires. After complaining and talking over with my tire guy, and telling him about my driving habits "logging roads" he said he never recommends siping tires that see lots of dirt roads. So onto my third set of the same tire non siped and lasted just over 60k. I will never sipe another tire again just for that reason. They do provide superior snow/ice traction but when tire life is cut in half it just isn't worth it to me. That being said most people don't drive on dirt roads often but felt it is worth mentioning.

i have decided not to sipe them due to i have been driving for the last 2 years on nearly bald tires. i think i can handle them just fine.

I have been running a set of DynaPro MT's 31x10.5 on my 90' XJ and living in northern Canada we see tons of snow and ice. I found for as aggressive as theses tire are they handle very well in all conditions.

Thats what I thought ya'll were referring to. Never knew people did that.

greengoblin

ok thank you if they do great for you then ill be just fine. i was asking because these are going to be my first set of mt's

Just wondering again...is this something you folks have professionally done somewhere or is it a DIY kind of thing?

xjsnake

Either or. A lot of people get them done as it's not particularly expensive but others like the idea of having control over how much siping and how deep to cut.

gpeade

Granted Im not from up north and I don't deal with the weather you folks do but this threw me when I read it. Im not trying to offend anyone here but with all the research, design, and testing that tire manufacturers do I cannot comprehend cutting on a tire to make it perform better.
Apparently it's a common thing to some but for me it seems outrageous.
Like I said I'm not trying to start an argument, just flappin my gums I guess.

I have had every set of tires I have bought for the last 20 plus years siped. I have the centers siped on my MTs and full siping on everything else. If you sipe the full face on your trail tires the outside blocks will chunk, that is why I only sipe the centers on MTs. I got 32K on my 40x13.5 r17 MTRs and would have gotten better but I did a lot of wheeling on shale rock.

Siped tires are better on snow, on rocks, on on most trails than unsiped tires, they are also better on pavement.
As for cutting a tire to make it perform better, most tires are not engineered to be used seriously for wheeling, they are of course engineered to perform better on pavement with less attention paid to trail use, because most tires are used on pavement 80-90% of the time.
