15in to 16in wheels

[27 TUG]

Hi everyone has any of you done this I got a Fiat Ducato 2020reg being under construction if I go to 16 wheels will it alter the speedo thanks Andy

 

[IRHP]

yes but they are never accurate anyway. If you want to know what speed you are really doing get a sat nav and compare it to your speedo. Every vehicle I've had always over reads so fitting larger tyres and wheels might actually make it more accurate.

Strange thing that on both the last two vans we had went to 16" and the speedo then matched the sat nav speed .

Hi it’s got a sat nav standard fitting will that be ok?

Yes the sat nav takes your speed from communicating with the satellites not the van.

It wont affect the speedo as they use lower profile tyres maintaining the correct rolling circumference of the tyre

Best to check on a tyre/wheel comparison type or two first.

Tyre Size Calculator

A better easy to use tyre size calculator. Use our tyre size calculator to find tyre diameter, width, sidewall, circumference, and revolutions per mile.

tiresize.com

Also, look out for final drive ratios for hill climbing too.

The older 16 wheels had a different pitch on the stud holes to the 15.
But the newer models are both the same so best have a quick check.
