what tires did you suggest

[Christian GM]

Hi guys,

I work a lot on H2 and H3, I know them like my pocket, but I have not a great experience on the fantastic H1...
So here are the question,
I have an H1 My 1998, with 37 12.50 R16.5 wheels & tires.
- They're really bad, and I'm thinking to replace both wheels and tires.
May I use a wheels set 17" x 8,5" swapped from a 2006 Hummer H2?
I know I will lost both CTIS and run flat, but is not really important for me know... If yes, what tires size up grade did you suggest (38" ? or 13,50 larger tires) and also, I will need a fender kit to use larger tires with H2 wheels?

thanks to all in advance!

regards
