A representative from Schrader presented a draft for a cost/benefit-analysis of TPMS. The draft was supported by further companies (Conti VDO, Knorr-Bremse, Beru, Entire Solutions LLC) but it is not a CLEPA or an ETRTO paper. The calculations in the draft which are based on a direct system show a very positive benefit/cost-relation even if the lower end of the range is taken for comparison. Besides fuel/CO2 saving and accident avoidance the TPMS can contribute a lot to tyre cost reduction because tyre wear increases considerably on under-inflated tyres.

There was agreement that the draft could be refined by taking into account further aspects like changing from summer to winter tyres or replacement/disposal of sensors and sealings.

However, it is obvious that the EU commission wants to use the potential for CO2-reduction which is given by TPMS and therefore further refinement of the cost/benefit calculation does not seem to be necessary.
