255/50-16 tires change ratio? 255/50-16 are 26inches tall, a few tenths of an inch tall than stock (25.7), will this chance my speedo a lot, should I get it calibrated? Is there a formula for the change in axle ratio? I have 3.42s, would this make it around 3.32 or something?

this is where I compare new tire sizes to stock:

I can't help you about axle ratio though.

IMO I don't think it's going to make much difference. I did the same change to MT 255 50 16 and I couldn't tell any difference. My shift points were still good. I think it may be like 1 or 2 mph difference. I wouldn't worry about it.

Not enough diffrence to worry about, I did the same change, and never bothered chaning the set up with my tuner. When I go to 18" x 10.5" rims, I'll take the trouble to enter the new numbers.
