Mickey Thompson et street r identification help please

[Jeepinxj]

I purchased a set lightly used for my 2014 GT and am trying to determine if they are bias ply or radials. Is there anything on them to identify? The size is 305/45/17 thank you in advance !

On the MT website for each tire you can look up the ID markings, near the bottom of the page.


MEDIUM SOFT
M7 X5 M5 L5 R2 R1 X8 L8 X7 L7 L2
To identify the compound of your current M/T® ET Drag tires look at the serial number on the sidewall of the tire.
EXAMPLE: CY1J M5 FJ2616
CONSTRUCTION

ST ...... Suggested for manual transmissions (medium compound)
W ...... Extra tread width (please note actual tread and section width on spec sheet)
S ...... Stiff sidewall construction aids in quicker reaction time due to less tire distortion. Also good in high horsepower applications and for heavy cars (Over 3,000 lbs)
R ...... Radial Construction

COMPOUNDS
L7 ...... For Motorcycles
L8 ...... Good Compound for General Use
L2 ...... For Jr. Dragsters
L5 ...... Good for High Horsepower - Boosted Applications
M5 ...... Good Compound for General Use
M7 ...... (Motorcycles Only) Good Compound for High Horsepower Applications With Clutch
X5 ...... Cooler running version of M5
X7 ...... Cooler running version of L7

Thank you, but there is no “b” for bias ply in the identifying codes from Mickey Thompson
Aren’t both models technically radials?

No they are not both radial tires, Radials and bias have completely different construction.

The tire size tells you what kind it is,

Radials are listed by their metric size ie, 305/45/17.

Bias ply by their American standard size, ie, 28x11.5-17

The DOT code you posted shows they were manufactured the 14th week of 2016.

Got it thank you! I have a manual should I wear them out then go bias ply?

Only if you also put bias ply tires on the front. You don't want to mix radial and bias ply tires on a car.
