my 2022 Jimny is in the Dominican Republic. I bought it new in 2021 and the only Suzuki dealership is over 2 hours away from where we live. (All the Jimny's imported here have automatic transmissions)

I'm seriously thinking about getting rid the stock 15" rims and tires and buying thru Jimny Style in the UK their retro style wheels - HIGH PEAK J-O1 and installing 16" Goodrich 215/70R16 tires. That's the tire size JimnyStyle is recommending with stock suspension and these rims..

What are the chances the TPMS will not work properly with the larger size wheels and tires? JimnyStyle is saying it will calculate fine and not to worry.

But the owner's manual has tons of warnings about going aftermarket w/different size rims and tires.

Does anybody have experience with this sort of thing?

Wheel size makes little difference as tpms is only looking at pressure inside the tyre.
As long as all 4 have the same rolling diameter ( this us the main issue to consider) then you won't have any traction control or abs problems,
Speedo calibration will change depending on overall difference in diameter.
Are you swapping the existing sensors into the new rims? If not, you need to code the new ones to the tpms system in the car.

Thank you for the information!

Yes, I plan on using the existing TPMS sensors if they aren't damaged upon removal-

So how do I measure the rolling diameter?

Diameter of wheels
As long as your rims are the same diameter and wheels are the same width and profile then the rolling diameter will be the same.

If one tyre is a different width or profile however then they won't be.

This is a handy site to work out the difference in tyres and gives speedo results

That website is fantastic!

Can I get your opinion on this please?

By upgrading the tires and rims from 15" to 16" there is a 2.2% difference in the diameter size.

The speedometer also is a bit off (2nd pic) - but that doesn't bother me.

Do you think I'll have a problem with the stock TPMS sensors by upgrading with the slightly larger rims and tires?

As long as the tyre pressures are the same tpms doesn't care about diameters, widths or anything else, they monitor pressures only
Your bigger concerns will be speedo accuracy
As long as all 4 tyres are the same size, width and profile then abs and traction control will be unaffected.

If using new sensors, you need a scan tool capable of coding the new sensors to match the existing ones ( cloning) do the existing tpms unit thinks it still has the original ones fitted, or you have to program the inboard tpms unit to detect the new sensors. Most reputable tyre shops will have tools to clone new sensors.
