TMPS swap?
 

Hay there,

did a bit of searching and it seems like this could work but just want to ask to make sure.

I have an 07 Mazda3 2.3 and I bought some 08 Mazdaspeed3 OEM 18 rims and slightly used tires. They did not come with the TPMS (tire pressure monitor system) stems installed. The seller told me it came with TPMS but the stems are just regular rubber stems so I am assuming they are not there.

My question is can I take the old ones off my 16" mazda rims and put those on my new 18" mazdaspeed rims? Guy at tire store said you could not or if you could the computer would have to be recalibrated but he didn't seem like the ultimate authority on the matter.

If possible would you guys do it? or is it not worth the hassle and $$ to have the tire store swap them out.

I would like to do it soon as I am going to sell the old rims and just want to make sure to take out the TPMS if I need them.

thanks

You should be able to do it. The main question is whether the TPMS sensors from your old wheels will fit tightly into the stem hole of the new wheels . . . and I think they should.

The mazda 3 system automatically senses the TPMS units, no recal / programming is needed with new parts. I've got a 2nd set in my winter rims from a 2006 and have no issues swapping tires.
