markmdz Haha. For me, yep that is short.

Yes, tons of work. The siping was about 30 mins per tire a few months ago. Now this was another 30 mins per tire again.

Rafikie That's short? Bahahaha nice job on the tires. Lots of work right there

markmdz ok, so thanks to my damn iPhone crashing on me I just lost my post, so I'll keep this one short and sweet...

The siping worked great and made the tires WAY better with wet traction, but given that I live in New England, wet traction is not as much of a concern as snow is right now. Siping doesn't help much at all in snow. So, I fired up the tire tool and flipped the blade to groove rather than sipe, and I went to town cutting the snot out of my tires.

Bear in mind, these tires don't have much meat left on them, and I'm too interested in seeing what I can do to improve traction and not worried about the value of the tires due to the limited tread remaining. I'm not sure I'd be so eager to cut up brand new tires, but I'm getting there now that I've had time to play with this tool.

Anyway, check out the pics and you can see the before and after of the two tires side by side, then a pic of the tire now with the grooves and the sipes (which are finally starting to open up a little, which is great). The shoulders (IMO) look pretty bad-ass now with the extra grooves in 'em too. Oh yeah, and a gigantic pile of rubber from cutting up my 4 tires (no I didn't cut up my spare yet. ...yet.)

Let me know what you guys think, and I'll definitely let everyone know if I made a colossal mistake, or a good move with all the grooving, considering we're expecting 1-1.5' (yes feet) of snow tomorrow.

markmdz honestly I would, but logistically it just doesn't make sense to ship it all over the place. I'd do it for the cost of the tool plus shipping, then refund all but $20 once I get the tool back. ...so basically $20 to rent it for x amount of time, but I don't lose out if it's not returned.

...kinda like AutoZone, except it makes no sense for me to refund 100% once returned.

jsahara00 Would you like to rent yours out?

The tool I bought is made by Ideal, and came with the very common #4 head (which is 1/4" wide) and a pack of blades.

I bought it from Speedway Motors, but they're all over ebay.

Deluxe 110 Volt 250 Watt Grooving Iron - Speedway Motors, America's Oldest Speed Shop

I would love to buy this head, which had 3 blades, for a total of 6 sipes per pass, or 3 parallel grooves, but I can't justify the price for as little as I'd ever use it.

Siper Head with Multiple Blades - Speedway Motors, America's Oldest Speed Shop

Although SpeedWay does carry two other sipers, which look very similar to the Ideal brand tools, I strongly advise not buying them. One of them does not use heat, which will make siping the tires a serious pain in the ass. The other tool (with the red handle) looks very nice, and I really like the fact that it has a detachable power cord, but even SpeedWay will tell you they're prone to melting after as little as 10-12 minutes. Each tire will take you about 20-25 mins, so the tool is basically worthless.

Good luck.

markmdz What tires do you have?

The main reason people say to avoid siping the outer lugs is to avoid chunking. If you drive primarily on pavement, this is not an issue. The fact though, is that the more edges your tires have, the better bite they'll have on the pavement which is especially important on wet/icy/snowy roads.

IMO, the best is to sipe the outer lugs as well, but just avoid the outermost 1/3rd or 1/2 of the lug to keep its strength, gain traction and still maintain the integrity of the part of the lug most susceptible to chunking.

Thats nearly identical to the tread pattern I have. Been reading the threads on here about siping and the general consensus seems to be just siping the inner two rows of lugs for some reason. Definitely want to do something to improve traction on wet and snow/ice slick roads this winter.

edit: after I got the hang of it on the first tire, the rest only took about 20 minutes per tire. I personally prefer the control you get doing it by hand rather than a machine siper.
Thanks, but I think it would cost me more in gas than to buy the kit! Let me know how traction is with the kit siping, I'll probably just order the kit. Besides, as soon as I do mine my daughter will want to use it to do hers! LOL

bmpage84 Thought of that but those hot knife kits are a PIA, and you don't get the nice multiple thin sipes like you do with a machine.
11-23-2012 09:42 AM
RubiconRich I would just sipe it myself a little heat on a hot tool and you should be fine.

Tire siping in MA/RI?

Anyone know of a tire shop in SE Mass / RI that has a tire siping machine? I've Google'd, called, or emailed most of the shops in my local area but haven't been able to find one.
Thanks
