(i) Apply a load through the block to the outer sidewall of the tyre at the distance specified in Figure 1 of this section for the applicable wheel size at a speed of two inches per minute, with the loading arm substantially parallel to the tyre/rim combination at the time of intervention. (iii) Resistance of tubeless tyres to bead loosening. When tested in accordance with section 159.5 (b), the force required to release the bead of the tire at the point of contact is less than: (1) A designation of the size of the tyre and a statement that the tyre is either an addition to a tyre category listed in the tables or that it belongs to a new category for which no table has been developed. (2) Each tire shall bear the DOT symbol in the manner specified in 49 CFR Part 574, which is an attestation that the tire meets applicable federal motor vehicle safety standards. (i) mount the tyre and wheel on a test axle and press a flat steel test wheel with a diameter of 67.23 inches and a width at least equal to the tread width of the tested tyre or an equivalent approved test wheel, the applicable test load being specified in Table I of Appendix A for the designation of dimensions; Type and maximum permissible air pressure of the tyre. (1) Preparation of the wheel-tire assembly. The tyre-wheel assembly shall be prepared as follows: This chapter specifies tyre dimensions and laboratory test requirements with regard to high-speed bead strength, strength, endurance and bead performance. defines the load capacities of tyres; and sets labelling requirements for passenger car tyres. 1. A maintenance device or special mobile equipment shall not be fitted with tunnels or guide belts which come into contact with the motorway and whose height or width is greater than those specified for the following categories and gross weights, with the exception of tracked or tracked vehicles: (a) dimensions and construction. Each tyre shall be designed to fit any rim indicated by its size designation in each reference given in the definition of the test rim in § 159.3 (in relation to the definitions). (ii) force and puncture recording at five test points evenly spaced around the circumference of the tyre.
If the tire does not break before the piston is stopped when reaching the rim, note the force and penetration when reaching the rim and use these values in point iii. Pennsylvania describes its traffic laws in the Pennsylvania Code (PC) and the Pennsylvania Vehicle Code (PVC). (2) Break the tire by running it at 50 miles per hour for two hours. The following tables list tire sizes and designs with the correct load and air values. The tables group the design tires and the associated air-load values. Persons requesting the inclusion of new tire sizes in the tables or the addition of tables for new tire models may, if the requested additions are consistent with existing units or if there is adequate justification for new tables, provide the Minister of Transport with five copies of information and data in support of the application. National Highway Traffic Safety Administration, U.S. Department of Transportation, Washington, D.C. 20590.
(2) Tyre dimensions, including height/width ratio, size factor, flange size, overall width and size of the test rim. (iv) the determination of the energy rupture value of the tyre by calculating the average of the five values determined in accordance with point (iii) of this paragraph. 2. Fines for non-compliance with point (c) relating to the period of use of tyre handles or studs shall be determined on the basis of the period of unauthorised use in accordance with the following table: (i) listed by name or brand of the manufacturer in a document made available to dealers of tyre manufacturers on request and in duplicate for: Tire Division, National Highway Traffic Safety Administration, 400 Seventh Street S.W., Washington D.C. 20590. It is illegal to drive or drive a vehicle whose tires exceed the body line of the vehicle. Section 175.65(a) of the Pennsylvania Vehicle Equipment and Inspection Regulations (Title 67) states: Condition of tires and wheels – Tires and wheels shall be in good working order as described in section 175.80 (with respect to inspection procedure). 1. Mount the tyre on a test rim with the rim width specified in Appendix A to this Chapter for this tyre size designation and pump it to the size specified in Table III of Appendix A. (i) it shall meet the size designation requirements referred to in paragraph 2, of the type and maximum permissible pressure. (v) Tyre maintenance.
If the tyre has been subjected to the laboratory endurance test provided for in Article 159(5)(d) using a test rim which does not undergo permanent deformation and does not allow air to be lost through the rim pressure chamber part, this Chapter shall apply to new tyres intended for passenger cars manufactured after 1948. However, it shall not apply to tyres which have been modified in such a way that they cannot be used or repaired as automotive equipment. Pennsylvania requires wings on all vehicles and wings and bibs on medium and heavy trucks. There is a maximum wing widening width of 3 inches and the wings must cover the entire width of the tire tread. (4) A statement as to whether the tyre size designation and load inflation plan have been agreed with the Tire and Rim Association, the European Tyre and Rim Technical Organisation, the Society of Manufacturers and Traders Limited, the Japan Automobile Tire Manufacturers Association, the German Industry Standard and the Scandinavian Tire and Rim Organisation. (A) One tire for physical dimensions, bead compaction resistance and strength one after the other. In the United States, 20 states require some sort of regular vehicle safety inspection. Make sure your tires don`t prevent your car from passing the state inspection. Buy tires exactly at the tread level you need. (ix) The tread of a tyre extends beyond the outer edge of the wheel arch, including the wing extensions.
A vehicle`s tires must not legally exceed a vehicle`s body line. A vehicle whose tires exceed the body line cannot be legally inspected in Pennsylvania. Wing extensions are permitted provided they are not more than three (3) inches from the flat portion of the vehicle`s wing. (i) Wash the tire, dry it on the beads and mount it on a clean, painted test rim without lubrication or adhesive. (1) General. Each tyre shall comply with the following information: 1 The letters H, S or V may appear in a particular size designation next to or instead of the “hyphen”. This chapter cites in 67 Pa. Code § 175.65 (for tyres and wheels); 67 pa. Code § 175.95 (for tyres and wheels); 67 pa. Code § 175.124 (for tyres and wheels); 67 pa. Code § 175.145 (on tyres and wheels); and 67 Pa. Code § 175.174 (for tyres and wheels).
Engine modifications and changes are not clearly explained under Pennsylvania law. 1. Unless otherwise provided for in paragraphs 2 and 3, each tyre shall be permanently shaped into letters and figures at least 0,078 inches high in or on both sidewalls, bearing the information referred to in points (i) to (vii). On at least one sidewall, the information shall be displayed within a range between the maximum width of the cut and the bead of the tyre. However, in no case shall the markings be placed on the tyre in such a way as to obstruct it by the flange of a rim designed for use with that tyre in accordance with the provisions of this Chapter and Standard No 571.110. (ii) Condition the tire mounting at 100°F plus or minus 5°F for at least three hours. 4. The studs or grouse of a crawler tractor or crawler tractor must have a flat surface with rounded edges; be perpendicular to the front and rear axles of the vehicle in such a way that five or more cleats on each surface come into contact with the highway; and shall not be less than 3/4 of the width of the tread or running surface. (ii) Physical dimensions. Each tyre shall meet each of the following criteria when measured in accordance with § 159.5 (a): (6) The outer diameter of the tyre shall be determined by measuring the maximum circumference of the tyre and dividing this dimension by ft (3.14). (4) The brake caliper is the width of the tread and the total width at six points distributed approximately evenly around the circumference of the tyre.
