Vlady 356 Posted January 7 Share Posted January 7 Hi all, I am planning to rotate allow wheels (not just the tyres) so that thread usage is more equal on all 4 tyres, the question is, how will Tyre Pressure Sensors will react to it? Does anyone know if they are coded in to a particular position on the car i.e front left or rear right? Any thoughts? Thanks Quote Link to post Share on other sites
Zotto 254 Posted January 7 Share Posted January 7 In my former GS 300h and now with RX I regularly rotate wheels and no troubles, , wheels position and pressure are correctly read. Else, if you add another wheel set with TPMS sensors you need to register them in car ECU. 1 Quote Link to post Share on other sites

If it is that easy than I am happy, as I said I am not sure how the system works, I guess time will tell. I am also planning to refurb the wheel and after that who knows which pressure sensor goes where! 😉 I was under impression that you need to code the sensor in to a particular side of the car. I do not have 2 sets of wheels, in Scotland you do not need (not a requirement) that but I have all season tyres which do just fine. Quote Link to post Share on other sites
Zotto 254 Posted January 7 Share Posted January 7 Hi Vlad, AFAIK in some cars there is only a receiver for TPMS sensors , so it needs to memorize the position where TPMS is, in our Lexus cars there is a receiver for each wheel housing, so the registration is only to link TPMS to car.

Does it mean no matter where the wheel is (what side) on the car , the pressure sensor will show correctly on a driver screen and it will be correct for each wheel, I mean the reading on the screen (lets say NS front) will show the pressure from left side front wheel? How the car knows which pressure sensor where to show it correctly on a screen, this is what I do not understand. Thanks Luigi. I booked wheel refurb for next week as well. Will see how it goes. Also the guy who will do refurbish of the wheels says that these pressure sensors might cause the problem as it is sometimes impossible to take them out, especially if it is a one piece sensor (there is also a 2 piece sensor) which needs to be cut if it is seized. I have no idea if I have a one or a two piece sensors. Does anyone knows it? Cheers Quote Link to post Share on other sites

Having a receiver on each side, car recognises the nearest TPMS signal as the valid one to be shown in that position. 1 Quote Link to post Share on other sites
rayaans 2,015 Posted January 7 Share Posted January 7 Ive always thought rotating tyres was an antiquated method nowadays. Surely its better to have fresh tread on one axle and slightly less on the other than having poor tread on all 4? Quote Link to post Share on other sites

I can see the logic of doing it BUT, would be worried it would open up a can of worms. If it ain't broke... Quote Link to post Share on other sites
Zotto 254 Posted January 7 Share Posted January 7 Rotating wheels is useful to have same wear on all tires. When doing it in wheels with TPMS you need to be careful to avoid damages to them, but a good tire dealer knows how to do it properly. Actually I am talking about rotating,tires , rotating wheels does not requires to dismount tires. 1 Quote Link to post Share on other sites

I was going to put rear tyres on front and vice versa. I had an repairable puncture (cut) on the front left tyre and ordered a new one, I want to put a new one on the back of the car and the one from the back move to the front.

Sherra 34 Posted January 7 Share Posted January 7 A close mate who has worked in tyres all his life (now retired) always told me that if you rotate then you always have to buy four tyres at once. Being a pauper at the time I always took his advice so could then spread the replacement cost. That was before directional became common.🙂 1 Quote Link to post Share on other sites
