Tires - To Sipe or Not to Sipe Toyo M154s

I agree with Toedtoes and valhalla.

But re-reading your OP for the second or third time, my impression is you're looking for validation for a decision you've already made. If so, just do it. No need to explain to us the decision.

Curious how an aftermarket business who does the siping (Les Schwab) can be held to the original manufacturer's (Michelin's). If you get them to agree, kudo's to you.

Good luck with your decision.

Actually... no. I had already decided against it. As I said in the OP, I was looking for your opinions. And I do appreciate them. Especially since they reinforce my own.

I left a clue in post #4.

After a lot of research, I was leaning away from the idea. That link... (and 2 subsequent links to be found within it)... was the final linchpin.

I will say this in favor of it...

1. IMO, the CR test was flawed... at least in terms of this particular debate. They used 2 tires that already had a ton of siping from the factory. These Toyos have virtually none. While the Michelins they've replaced... do.

2. Other than CR, virtually every expert said the siping would likely garner better wet, snow and ice performance; possibly at a loss of tread life. But it's a virtual certainty that these Toyos will be changed out within 6 or 7 years... likely with something like only 10,000 miles. This rig is a family camper. Not a globe trotter.

But... of course... there is also the possibility of greater road noise, lesser dry performance... death of the warranty... and... I just don't like the idea of taking decades of engineering out of the experienced engineers' hands... and placing it into those of a tire shop.

Also... the tires were well proven by the previous owner... whom I knew very well. He just didn't do much driving in the rain and zero in the snow.
