1)I'd stay with 18's, maybe even 17's. IMHO, 19's are just too much ... weight

2) Widest - Rim 8 to 8 1/2 inch, tire 225 to 245, would recommend 7 1/2 to 8.3) The rim should have a load rating value on it, usually in kgs. I think the 97 needs either 670 or 690kgs
Any particular style? I'd look for the 5-spoke 17's or some M45/(newer)Q45 18 inch take-offs.
