Adjust Shop Tire Pressures For Operation In Cold Temperatures{4203,4204}
Usage:
When a tire is inflated (filled with air) in the dealer's shop when the shop temperature is 65°-70°F (18°-21°C), it will be under-inflated if the machine is operated at much lower outside temperatures. This will cause shorter tire service life. You must adjust tire inflation (fill) pressures in the shop so the tires will be at the correct pressure for colder outside temperatures. The chart gives pressure recommendations for tires inflated inside the shop according to colder temperatures outside. When a tire is inflated outside the shop, fill it to the original pressure recommendation.
