Steeljag With the tires in my sig I'm off 7 mph at 57 mph. With GPS reading 57, speedo reads 50mph.

Water Dog Speedo's are going to run off at a percentage, and not a fixed number. 10%= 1mph off at 10mph, and 10mph off at 100mph etc. so you're going to see a larger amount off at 65mph than at 30mph.

wwch99tj Speedos aren't 100% accurate from the factory sometimes with 31's it makes them read correct...
Mine, 4 cyl 5 speed was off by about 9% (slower) with 31's...

Tire size change speedo change?

Alright so I went from stock 29s on my 97 to 31s. Speedo should be off correct?
When I check it with a speed app on pho e it's dead on so far up to 35mph... But I know I know at 65 it's off.
