Going to set the wheel size on the truck here soon and am wondering for those of you w/ these tires where did you start and where did you end on the Revs per mile using GPS. looking to possibly save a little time w/ fine tuning if I can get close to start.

Thanks all

 

BFGs website lists the revolutions per mile.......

 

I looked on BFG's website and couldnt find the RPM calculator.

 

Try this www.tires.com/TireSizeCalculater.asp

 

on second look www1010tires.com/TireSizeCalculater.asp

 

The info is all listed on their website.........

Just two sizes, from the many listed:

LT305/65R17/E: 636 Revs Per Mile @ 45 MPH

LT315/70R17/D: 601 Revs Per Mile @ 45 MPH

 

D45...........any ideas why BFG states the tire revolutions per mile "@ 45 mph" ? Does the tire revolutions per mile change above or below 45 mph ? Kinda leaves me scratching my head a bit.............

 

D45 probally just cut and pasted from their website the 45 MPH. Still weird to me as well.

 

Thanks guys BFG also says this tire is 34.5" but when you measure it from the ground up its closer to a 33.5".

I will start w/ the revs on website and verify w/ GPS, and go from there.

Thanks,

 

i believe its like 601 at 45mph... thats what i told my dealer when i had my speedo redone. its on their website, and my speedo is pretty on the mark.

 

They must grow at higher speed I wonder what the revs are at 80 MPH?

I'm beginning to not like those big balloons. The 315s seemed really good when I first installed them, but they get out of balance and noisy as time goes on. They are great for off road traction but my truck steered lousy with them. Now, after getting the new Toyos with a MUCH stiffer sidewall, I'll never go back!

mine didn't like the revs per mile that the web site said; so it took a little tweaking. I think that mine is set a 594.

 

It sounds like you drive about 80 MPH most of the time Watch out, they're growing.
