18s tyre size and speedo variance

[Dizzy]

we're coming up on some new boots for Dizzy. Currently running the standard black 18s with 255/45/18 bridgestones.

We've got some 17s with Michelin CC (cant remember size but standard 215s) which we run in the winter.

I was contemplating a higher profile 55s on the 18s. 235/55/18, but i see they have a -4.6% speedo variance, rationale a more comfy ride.

Anyone done this ?

or should i look at vb 4c ?

Just use Google maps, it shows the real speed of the vehicle regardless of tyre size.

I assume you are suggesting changing the software to suit the new size. According to the T6.1 forum it can be done but oddly there is a risk of not being ablle to undo the change. Suggest you research carefully on the method of changing it. This is just bits and pieces I have read in the past through curiosity so not definitive.

I found 255/45/18 uniroyal rain sport tyres to be the most comfortable of all the sizes I tried. Really good handling in the wet & quite a soft sidewall to give a compliant ride.

We run 235/55/18 Michelin cross climate 3s and been very happy with them. Comparing Speedo with Google maps etc it reads pretty much spot on. Comfortable ride and look better with a bit more sidewall in my opinion

interesting, i suspect the size opens more options as well.

I shouldn't guess at what I didn't understand

Exactly the same tyres and same experience with speedo/google maps
