TPMS

Post by Stubutler » Thu Jan 07, 2021 11:03 am

Hi I'm looking at getting some 20 inch alloys and tyres to replace my 19s. Will my 19s TPMS be a straight swap onto the 20s or are they different on the 20s. Currently the 20s have no TPMS where as my 19s do.
Thanks.

As far as I understand it, the TPMS sensors are built into the valves - so provided you swap the valve assemblies over to the new wheels, they'll continue to work and the car won't know the difference.

Thanks. I phoned a tyre shop and he said as long as seating is the same it should be ok but he did say they can vary.

Be aware that at build, the TPMS system in the vehicle will have been programmed for 20” wheel tyre pressures. Whilst the fronts are the same between 19 & 20” wheels, you will need to drop the rears by 2psi (35 as opposed to 37) to prevent over inflation. Unless you are planning on permanently keeping 19’s on, it’s simply not worth having the vehicle setting updated for this minor issue.

Thanks for that information. At present the sensors are on my 19s and would be moved to the 20s

Apologies, I was muddled there. In which case, increase the rears by a couple of PSI and ignore the IC suggested numbers.
