I just got p45r and the tireshop guys put tpms from oem wheels to new wheels.
I currently have fk452 245-40-18 for front, and 275-40-18 for the rear.
My friend says they don't fit on rota wheels. But it seems like working well.
On last night I saw a low pressure tire light. So I just put some air on front driver's side tire. Do you guys think the tpms is not perfectly fit so the air is leaking or just coincidence?
I am curious why other tires are fine but front driver's side tire is not.
Please help me!
p.s. front tire pressures are 36 each and 40 for rear

 

What's your rim size and what pressure are you putting in the tires?

 

TPMS fits fine in my rotas.

Watch your air pressure, if it is a leak, it is not because the tpms doesnt fit, its because someone made a mistake... maybe the core in the valve stem is leaking?

 

What was the pressure last night, what is it this morning? If the TPMS fit in 3 wheels, it fits in the 4th one. Just monitor your pressures, and if you have one tire that keeps leaking, bring it back. On new wheels and tires, the most common leak is in the valve stem. Shops usually charge more to mount tires on wheels that have TPMS because they are liable for the damage, and when they mess them up, it's expensive to replace (new TPMS, trip to the dealership to sync it, etc.).

 

^ What he said.

 

Unless you swap the sensor..when you get aftermarket rims/tires that light will come on, its just something you gotta live with..

 

like everyone said monitor the tire pressure. tmps comes on, and it gets annoying after awhile. heres a trick i learned when checking for leaks. grab an empty spray bottle, clean your wheels and inflate if needed, spray on certain spots of the wheel. watch and if you see bubbling more than likely that your leak.

I use to do this on my bike when i was a kid lolz

 

/close thread.

 

Could spray the wheel and look for leaks or take back to the shop and put in a dunk tank if they have one. Easiest way to find the problem.
