Modified wheel hubs of literacy + IS300 personal analysis of alteration
seen so many friends to this wheel, just want to change themselves. . . Read some useful posts feel the need to let everyone see posted, so happened to buy back wheel on the tragedy that is not installed,
belstaff jackets sale!
modified tires must first understand the type of tire, the tire model includes a tire information. Take IS300 front tires,
belstaff leather, size 225 45R/17. 225 is the tire width in millimeters. 45 is a flat rate of the tire, units%,
belstaff jackets, the smaller the value representative of the more flat tires! 17 is the wheel diameter, but it is inch, 1 inch = 25.4 mm
then IS300 front wheel size as follows: 225 * 45% * 2 +17 * 25.4 = 634.3 mm
IS300 rear wheel size as follows: 245 * 45% * 2 +17 * 25.4 = 652.3 mm
when we converted to Note: 1, the width of the tire after the change not affect the steering
; 2, new tires and the original size of the diameter consistency as possible, otherwise it will affect the speed of the table,
belstaff online, the maximum speed of the basic values.
the following modifications to my IS300 wheels provide me with a few ideas of their own programs, I want to change the 18-inch wheels
do your homework first 17-inch wheel diameter is 17 * 25.4 = 431.8 mm
18-inch wheel diameter is 18 * 25.4 = 457.2 mm
front tire program 1:225 40R/18 diameter of 225 * 40% * 2 +457.2 = 637.2 error rate of 0.4%
program 2:235 40R/18 front tire diameter is 235 * 40% * 2 +457.2 = 645.2 error rate of 1.6%
front tire diameter programs 3:235 35R/18 235 * 35% * 2 +457.2 = 621.7 error rate of -1.9%
program 4:245 35R/18 front tire diameter is 245 * 35% * 2 +457.2 = 628.7 error rate of -0.8%
program 5:255 35R/18 front tire diameter is 255 * 35% * 2 +457.2 = 635.7 error rate of 0.2%
comprehensive look at 255 35R/18 closest to the original diameter size, appearance is also the best, but there is a problem that too much friction, and will seriously affect the car's acceleration and fuel consumption that is steel steel ,
belstaff motorcycle jackets! ! 225 40R/18
configuration of personal recommendations, both to maintain almost the same as the original, and not affect the car's acceleration and fuel consumption
the following programs to analyze the rear wheel
Option 1: 245 40R/18 tire diameter of 245 * 40% * 2 +457.2 = 653.2 error rate of 0.1%
program 2:255 40R/18 rear tire diameter is 255 * 40% * 2 + 457.2 = 661.2 error rate of 1.3%
program 3:255 35R/18 rear tire diameter is 255 * 35% * 2 +457.2 = 635.7 error rate was -2.5%
rear Scenario 4: 265 35R/18 tire diameter of 265 * 35% * 2 +457.2 = 642.7 error rate of -2%
program 5:275 35R/18 rear tire diameter is 275 * 35% * 2 +457.2 = 649.7 error rate of -0.3%
program 6:285 30R/18 rear tire diameter is 285 * 35% * 2 +457.2 = 656.7 error rate of 0.6%
as the truth 275 35R/18 best, but seriously affect the speed and fuel consumption
personally recommend 245 40R/18
goal is to change all my front: 225 40R/18
After: 245 40R/18
this configuration in appearance, acceleration,
belstaff brad jacket, fuel consumption , the error rate can be achieved almost perfect balance
