488 TPMS readings across front axle

On the F8 there is a radiator outlet near the front left axle that creates the same anomaly. I suspect its the same issue on the 488 and if so it is a consequence of the car's design and not a sensor issue.

 

Yep, same on my 488 GTB. Engine coolant radiator exhausting into left front wheel well is the culprit. Microsoft would probably call it a "feature."

 

my 2013 458 does this, too. front left always a few degrees higher. same explanation? radiator exhaust?

 

Front left always reads higher on my 458 as well. I replaced all four sensors last fall.

 

Normal.

 

Same. 2018 488. What 'docster' wrote.

 

Unless you do a lot of miles the batteries in your TPMS sensors should last a few more years, at least long enough to not worry for this tyre change. I have a car that is 13 years old and still running original TPMS

 

Normal. Adjust your presure accordingly. Get the left down 0.1 bar.

Unless somethings off, those TPMS sensors will last a long time. No need to change them.

Mine lasted exactly 7 years. I replaced tires and didn’t replace sensors, and within a month two had failed. So it was back to the shop to replace all four.

I believe I read somewhere 7 years is the expected lifetime. They’re not that expensive online, so act accordingly…….

 

Same here - 488 Spider (UK RHD) - front left tyre consistently reads up to 5C hotter than the other, especially with spirited driving; rears are always consistent. I had been a bit concerned about it; interesting to hear about the radiator outlet and that would certainly explain it.

 

I run my left front .5psi less when cold than front right. I’m very ocd plus when warm at speed I’d rather have the front psi match more closely
