I'd really appreciate some help with actual measurement of some BFG TA KO tire diameters.

There are lots of ideas about how to best measure a tire. I'm just after an apples-to-apples comparison. Please measure across the tire, side to side, and measure to the crown of the tread, not the shoulder. I use a pair of framing squares clamped together in a big "U".

I know the diameter BFG publishes. I'm after the real world diameters.

Sizes I need:
265/70r17
275/70r17
285/70r17

If you know the tire pressure and rim width you're running that would be great, but I'd be grateful for just the measurement.

Thanks much!!

 

Bump. Somebody?

 

Can't help, I'm running the 305x70x17's.

 

Heres a good conversion site.

Thanks much for the conversion link. What I'm after is the difference between the actual measured diameter and the advertised diameter. They are rarely the same.

 

Rule of thumb I've found for BFG mt and at tires is to knock off about 1/2" from advertised height.

Example:

My set of 31x10.5t15 AT ko's actually measured 30.5 on my old ZJ. From memory, same thing for the rubi tires. Billed as a 32" tire when it measures just a hair over 31".
