Want to get bigger tires and saw the thread here showing biggest tire u can put on stock height... But what is the biggest tire size I can put on my stock 15" wheels without needing to change my speedo gear?

this only answers which tires will physically fit onto the ex. Gear ratios are not stated here

This offer the part numbers, number of teeth, and the math to figure out how much correction is needed based on the tire size change. You should be able to pull it together from there.

Here's a broader list of links about tire sizes and speedo gears (among other things)

There's great stuff here. All you have to do is dig a little.

Any change of the tyre size will effect the speedo.

Your speedo won't be accurate anyway.
