ST1-ST4 NSW Tire Measurements

The use of labeled tire sizes will be discontinued on May 31, 2018, and only the NASA Section Width will be used to determine tire size compliance.



6.5.2 Tire Size

NASA Section Width 266mm or smaller (DOT-approved)

Or any currently produced size 245 or smaller = +0.6

NASA Section Width 267mm to 282mm (DOT- approved)

Or any currently produced size 275 = +0.3

(Note: Deletion of the use of labeled tire size occurs May 31, 2018)

Sorry if this is dumb, but Im about to spend 1K on new tires and I dont want to make a mistake. According to the 2018 TT rules, you can still get whatever tires/size you want, those sizes listed above are simply the only ones that come with a power/wt 'adjustment' right? Ive run 315/35/17 since 2007 and dont want to change, my car weighs 3700lb. Thanks
