If the Michelin tires are siped by the manufacturer, then I would contact them and ask why they need to sipe them before making a decision. If they are siped aftermarket but before purchase, then I would not buy from that shop.

I guess I thought the point was clear.

The Michelins... are the OEM. And the OEM tread. They are siped.

BUT... they are known to be of poor quality. And not because of the siping.

The Toyos are considered to be (by motorhome owners)... one of the best replacements. But they are not the same tire... nor tread... as the OEM. They are really a commercial steer / trailer tire. Great for steers. But less than ideal for drives.

There is no ideal choice here. There is no "solution... to replace them (the Toyos) with different tires." The unique size leaves fewer than usual options. One can have a "best" solution without it being an ideal one.

Ah! So you bought the RV with factory siped Michelins already on it. And are deciding to replace with the same (factory siped michelins) or Toyos.

In that case, my last comment stands. I would question Michelin as to why they sipe their own tires. Is it done in accordance with their engineers to provide the best tire? Or is it a cheap fix for an engineering mistake?

My guess would be the latter.
