Bronco Raptor Factory Tire Size?

[FellowM3]

What size tire does the braptor come with?

I know press release said 37x12.5 on 17s, but trying to see how it comes compared to the SAS.

SAS is 315/70/R17.
Is the Braptor 315/80/R17?

My tire size calculator only uses the tradition mm

how do these compare in height and width exactly to the sasquatches 315/70/r17?

34.4X12.50R17 for Sasquatch (considered at 35x12.50, but its shorter)
37X12.50R17 for Raptor
I don't think there is a millimeter tire size equivalent for a 37" tire.

Sas Goodyears are 34.4" diameter and measure 12.7" width on a 9.5" wide wheel.
Raptor KO2's are 36.5" diameter and measure 12.5" width on a 10" wide wheel

How’s you get the 36.5” diameter ?

my confusion is if it’s a 315/80 or a true 37x12.5

I’ve just never seen a tire in inches (like 37x12.5 lol)

Those are the specs per BFG's website. It is a 37x12.50x17. Tire sizes listed by inches is common for large tires.

315/80 = A/B
1 inch is 25 mm
to convert width take 315 divide by 25 = 12.6
to get sidewall, B is a % of A, so 315 * .8 =252mm. this is total side wall (above and below the rim), youll need to divide that by 2 if you're only measuring the side wall radius which is 126mm, or 5"
