TITLE: FMVSR INTERPRETATION

TEXT: This responds to your May 6, 1977, letter asking whether your tire information label complies with the requirements of Standard No. 120, Tire Selection and Rims for Motor Vehicles Other Than Passenger Cars, and Part 567, Certification. Further, you request that the National Highway Traffic Safety Administration (NHTSA) expedite treatment of Docket No. 73-31; Notice 1, which, if implemented would simplify the certification and information labels.

Concerning Docket 73-31, the NHTSA published on June 20, 1977, a notice (42 FR 31161) implementing Notice 1 which proposed the use of the designation "all axles" rather than listing each axle individually on the certification label. The implementation of this regulation should resolve many of your problems.

Regarding the sample information label you submitted with your letter, the NHTSA does not give advance approvals of compliance with Federal safety regulations or standards. We will, however, give an informal opinion of whether your label appears to comply with the requirements. The label you submitted does not appear to comply with the requirements of Part 567 or Standard No. 120. I have enclosed copies of both of these regulations for your information.

Your certification label should use the designation "all axles" not "each axle." The tire and rim information should follow that designation stated in the form presented in the examples in Standard No. 120 and Part 567.

SINCERELY,

TIMPTE, INC.

ATTENTION: JOAN CLAYBROOK, ADMINISTRATOR

WE ARE A MANUFACTURER OF SEMI-TRAILERS, BASICALLY REFRIGERATED VAN TYPE TRAILERS AS WELL AS GRAIN HAULING TRAILERS OF SEVERAL TYPES. THESE ARE HIGHWAY OPERATED UNITS AND ARE NON-EXEMPT FROM ANY FEDERAL STANDARDS INCLUDING 121. THE 60 M.P.H. RATING IS STANDARD ON ALL OF THEM AND IN THIS CONTEXT, WE WOULD LIKE TO PRESENT OUR PROBLEM AND ASK FOR YOUR ASSISTANCE IN EXPEDITING ACTION AS WELL AS ADVISING OF YOUR CONCURRENCE OR NOT WITH OUR INTERPRETATION OF PART 567, AS WELL AS STANDARD 120. AS YOU KNOW, IT IS NECESSARY THAT WE AS MANUFACTURERS, CHANGE OUR CERTIFICATION PLATES AND TIME IS NOW OF THE ESSENCE OF OBTAINING DELIVERY SO THAT IN ORDER TO BE IN COMPLIANCE, IT BECOMES NECESSARY FOR US TO ACT RATHER QUICKLY.

PERTINENT TO THIS IS THE FACT THAT DOCKET #73-31; NOTICE #1 CLOSED COMMENT ON JANUARY 7, 1974 AND NO RESPONSE FROM NHTSA HAS BEEN FORTHCOMING, IN SPITE OF WHAT WAS APPARENTLY FAVORABLE POSITIVE COMMENT ON THE PROPOSED RULE-MAKING. THE AMENDMENTS PROPOSED TO PART 567.4 AND 567.5 WOULD GREATLY SIMPLIFY THE LABEL ITSELF AND YET NOT DETRACT FROM THE INFORMATION THEREON. SINCE NEARLY ALL OF THE HIGHWAY TYPE SEMI-TRAILERS MANUFACTURED HAVE IDENTICAL AXLES AND TIRES AND HENCE, GAWR RATINGS, IT SEEMS ONLY APPROPRIATE THAT A SINGLE GAWR RATING BE ALLOWED INDICATING THAT THAT IS FOR EACH AXLE OR ALL AXLES ON THE TRAILER. COMPARE THIS TO THE NECESSITY OF HAVING TO LIST FRONT, INTERMEDIATE, AND REAR AXLE GAWRS INDIVIDUALLY WHEN, IN FACT, NEARLY 100% OF THE TIME THEY ARE THE SAME. ON THOSE OCCASIONS WHEN THERE MIGHT BE A DIFFERENCE, THEN GAWR FOR THE DIFFERENT RATED AXLES WOULD BE REQUIRED. FURTHER, THIS NEED NOT MODIFY THE CONTEXT OF STANDARD 120 SINCE IN S5.3 (A) THE REFERENCE IS TO CERTIFICATION LABEL AS REQUIRED BY PART 567.4 OR 567.5.

ACCORDING TO OUR INTERPRETATION OF 120 AND WITH THE AMENDMENT AS PROPOSED IN DOCKET #73-31; NOTICE #1, OUR CERTIFICATION PLATE WOULD COMPLY AS SHOWN IN THE ATTACHED DRAWING 044-027A. S5.3.1 AND S5.3.2 CLEARLY ALLOW TIRE AND RIM DESIGNATIONS NOT NECESSARILY THOSE ON THE VEHICLE, BUT SUBSTANTIVE OF THE GAWR SHOWN. S5.1.2 IS COMPLIED WITH IN THAT 10:00X20F, RIMS 7.5 AT 75 P.S.I. COLD DUAL, IS THE MINIMUM TIRE THAT WILL GIVE THE GAWR OF 19,000 LBS. WHICH AGAIN IS THE MOST COMMON ONE IN USE TODAY DUE TO OTHER LIMITING FACTORS OF THE SUSPENSION, AXLE, WHEEL AND BRAKE SYSTEMS. OF COURSE, THE NEXT TO THE LAST SENTENCE WOULD BE COMPLIED WITH AND DOES ALLOW FOR TIRES FITTED TO THE AXLE NOT APPEARING ON THE CERTIFICATION LABEL. IN ALL CASES, THESE TIRES WOULD BE IN EXCESSIVE RATINGS OF THOSE WE WOULD HAVE PRINTED ON THE LABEL. FROM A PRACTICAL STANDPOINT, MANY OF OUR TRAILERS BEING SOLD THROUGH DISTRIBUTORS AND/OR DEALERS ARE EQUIPPED WITH TIRES OF A CERTAIN SIZE LEAVING OUR PLANT; HOWEVER AT VARIOUS LOCATIONS THROUGHOUT THE COUNTRY, WHEN HE DISTRIBUTOR OR DEALER IS SELLING THESE TRAILERS FROM STOCK, THEY MAY BE EQUIPPED WITH A DIFFERENT SIZE TIRE, YET ADEQUATE TO SUSTAIN THE GAWR.

THERE ARE TWO MORE POINTS IN REGARD TO THAT CERTIFICATION TAG AND ONE OF THEM IS POSSIBLE ELIMINATION OF THE ABBREVIATION OF THE WORD MINIMUM PRECEEDING TIRES. WHILE IT IS FACTUAL, IT IS NOT INDICATED IN THE STANDARD. THAT CAN EASILY BE ELIMINATED IF IT WAS NOT IN ACCORDANCE WITH YOUR INTERPRETATION OF THE STANDARD. THE OTHER ITEM THAT WE FEEL MIGHT BE DESIRABLE TO DO IS HAVE IN PLACE OF THE BLANK IN WHICH WE MUST STAMP NUMBERS OPPOSITE GAWR EACH AXLE, TO HAVE THAT PRINTED IN AT THE TIME OF THE MANUFACTURE OF THE LABEL IN THE SAME MANNER THAT WE WOULD THE TIRES AS SHOWN PRINTED IN. THE NUMBER WOULD BE 19,000 LBS. AS MENTIONED, THIS IS THE NEAR UNIVERSAL STANDARD RATING ON AXLES IN REGARDS TO VARIOUS OTHER LIMITING STANDARDS. THIS OF COURSE, LEAVES A MINIMUM OF ITEMS TO BE STAMPED IN ON THE PLATE AND STILL GIVES THE TOTAL INFORMATION REQUIRED. BUT FOR ANY POSSIBLE EXCEPTIONS THAT MIGHT OCCUR, WE WOULD PROPOSE USING A PLATE SIMILAR TO 044-027, THEREIN WE WOULD BE STAMPING ALL OF THE INFORMATION AND WE WOULD SUSPECT THAT THIS WOULD ONLY BE USED POSSIBLY 5% OF THE TIME.

I WOULD LIKE TO EMPHASIZE ONCE AGAIN THE URGENCY FROM A STANDPOINT OF TIME AND REQUIREMENTS FOR ORDERING, MANUFACTURING AND DELIVERY OF THE CERTIFICATION PLATES TO US. EXPEDITED FAVORABLE ACTION ON DOCKET #73-31; NOTICE #1 WILL GREATLY CLARIFY THINGS FOR OUR ENTIRE INDUSTRY AND WHILE IN THE INTERPRETATION AREA, WE ARE SPEAKING OF OUR OWN PLATE, THIS TOO, WOULD BE CLARIFIED BY AN OPINION FROM YOUR OFFICE. THANK YOU.
