When the ford website says SVT tuned BFG ATs , what are they talking about? What is different?
I saw this response in another forum
"The tires are VERY similar & unless you spend all day looking closely at tires you'll not notice any difference. BFG does make a specific All Terrain T/A KO for the Raptor LT315/70R17 121S MSPN#37614 The "other" LT315/70R17 121R is MSPN#54142 & was made originally for the Hummer H2, both are available through BFG dealers. There are a few differences one is a slightly different tread compound, but I don't believe that I would say it's softer, but has different traction properties. There is the different speed rating S=112 mph vs R=106 which requires some additional reinforcement inside.
The easiest thing to say is it was developed along with the Ford engineers for the Raptor, not unlike Fox developed a shock with Ford engineers so that the end platform met their specs."
Other than that I do not know.
