The high cord angle, combined with a unique tread design, reduces rolling resistance for increased speeds, while their shallow tread depth increases stability at high speeds. Lastly, a stronger mounting bead withstands higher pressures when adjusting for roll-out. \u003cstrong\u003eSpecs:\u003c\/strong\u003eTire Size:5.50-15\u003c\/p\u003e  \u003cdiv\u003eWheel Diameter:15 in.\u003c\/div\u003e  \u003cdiv\u003eSidewall Style:Blackwall\u003c\/div\u003e  \u003cdiv\u003eTire Construction:Bias-ply\u003c\/div\u003e  \u003cdiv\u003eTire Diameter:25.20 in.\u003c\/div\u003e  \u003cdiv\u003eTread Width:3.50 in.\u003c\/div\u003e  \u003cdiv\u003eMinimum Recommended Wheel Width:3.50 in.\u003c\/div\u003e  \u003cdiv\u003eMaximum Recommended Wheel Width:4.00 in.\u003c\/div\u003e  \u003cdiv\u003eDirectional:No\u003c\/div\u003e  \u003cdiv\u003eAsymmetrical Tread Pattern:No\u003c\/div\u003e  \u003cdiv\u003eDOT-Approved:No\u003c\/div\u003e  \u003cdiv\u003eTube Required:No\u003c\/div\u003e  \u003cdiv\u003eSidewall Ply Quantity:2\u003c\/div\u003e  \u003cdiv\u003eQuantity:Sold individually.\u003c\/div\u003e  \u003cp\u003e\u003cstrong\u003eConverting Standard Inch to Metric Size\u003c\/strong\u003e\u003cbr\u003e Sometyres use an LT sizing which uses Imperial dimensions. A 31X10.5-15 tyreis 31\" Diameter, 10.5\" Wide to suit 15\" Rim. Below is a guide toback-convert LT sizing to metric sizing:\u003cbr\u003e ■\u003cstrong\u003eInch Size: 31×10.50-15\u003c\/strong\u003e\u003cbr\u003e First, we already know the width of the tire (10.5 inches) so we can convert that number to millimeters by multiplying by the number of millimeters in an inch (25.4 millimeters per inch):\u003cbr\u003e ■\u003cstrong\u003eTire Width: 10.5 inches X 25.4 mm per inch = 266.7 mm\u003c\/strong\u003e\u003cbr\u003e Metric sizes are most often quoted in even divisions of 5 mm, so we can round the above result down to 265 mm.\u003cbr\u003e Next, we need to detemine the sidewall height. To find the sidewall height, we take the tire's overall diameter (31 inches), subtract the diameter of the rim (15 inches), and divide that number by 2:\u003cbr\u003e ■\u003cstrong\u003eSidewall Heigh ( 31 inches - 15 inches ) \/ 2 =8 inches\u003c\/strong\u003e\u003cbr\u003e Now that we know the sidewall height, we can find the percentage value used in the metric sizing standard by dividing the sidewall height (8 inches) by the tread width (10.5 inches):\u003cbr\u003e ■\u003cstrong\u003eSidewall Percentage:8 inches \/ 10.5 inches = 0.76 = 76%\u003c\/strong\u003e\u003cbr\u003e Like the tire width, the tire's sidewall percentage is quotes in units of 5, so our tire sidewall percentage is somewhere between 70% and 75%.\u003cbr\u003e So, based on our calculations, a 31×10.50-15 tire is approximately equal in size to a 265x75r15 tire. Be aware that sizing can never be an exact match from metric to imperial sizing.\u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e","brand":"Moroso","offers":[{"title":"Default Title","offer_id":44666236600631,"sku":"MO17050","price":497.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/104157.jpg?v=1780796355","url":"https:\/\/enginemaster.com.au\/products\/moroso-mo17050-tyre-drag-special-front-25-2-x-5-5-15-bias-ply-blackwall-each","provider":"Engine Master","version":"1.0","type":"link"}
