Bigger Tires Warranty Question

[MisterE]

Hey All,

I have a question about larger tires. This H3 is a lease which I will either buy out or buy the next one (which ever works out cheaper) my big plans are going to be a winch and tires that I can transfer over if needed. I have the 285's that came with the Adventure but would like something with more bite to them. I'm looking at BF AT or MT but I am unsure if I should stick with 33's or go up to 35's. I know that given a problem the dealer must specifically prove a modification caused that problem before they void your warranty on a part (eg an aftermarket radio may void your speaker warranty but not your drivetrain warranty). With the extra weight of 35's on the rotors, tierods, calipers... and such do you see this being a problem or is it such a small amount am I being paranoid?

If anyone wants to chip in on if the MT are siped, thought they weren't but coundn't find it on the website and I will be in the snow (hopefully not to much) in Michigan this winter.

Thanks,
