ST-rated tires are engineered for trailer axles only. They must never be fitted to a driven axle or a steering axle on a car, truck or SUV - the casing is built stiff to resist trailer sway and is not designed to transmit drive or steering loads.\u003c\/p\u003e\u003cp\u003eST tires also carry speed limitations. The M symbol on this size corresponds to 81 mph, but many trailer manufacturers and several states impose lower towing limits, and running an ST tire near its ceiling for long periods builds heat quickly. Treat the marking as a ceiling, not a target.\u003c\/p\u003e\u003cp\u003eThe dual marking 132\/127M means 4,410 lb in single fitment and 3,860 lb per tire when mounted in duals, at 14 ply rating (Load Range G). This is legacy part number ST340-I0131354 for Atturo's ST 340 Special Trailer radial, available to order at Rev Auto Club.\u003c\/p\u003e","brand":"Atturo Tire","offers":[{"title":"Default Title","offer_id":48791695294621,"sku":"ATTST340-I0131354","price":219.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0448\/7997\/0461\/files\/1db09af2dd3b235b1b7b6fa029e91761L_d85c3dd8-7597-48c5-8505-e9c2a35c01dc.jpg?v=1786572143","url":"https:\/\/shop.revautoclub.com\/en-rd\/products\/atturo-st-340-trailer-tire-st235-85r16-132-127m-14pr","provider":"Rev Auto Club","version":"1.0","type":"link"}
