Am rolling on "37" BFG Km2's which really only measure 36" on a good day. I needed a full size spare so I got my next choice of rim and tire a 37x13.50x17 Toyo MT which is a true 37" tire ... I decided to take a couple of shots of the difference. After seeing the true 37 on there it gets me to thinking, shit maybe I should just go to 38x13.50 on 18 or don't shoot me 20's. What do you guys think? I know I only have a D30 right now but I do have it sleeved and gussetted and only do light wheeling on the weekend. I will go with a PR 44 when money permits. Thoughts? And of course "the seal"!

 

That be a heavy ass tire to get on a D30. Love the Toyo's but they're just too heavy for my taste. What tire pressure are you running in your KM2's right now to make them measure out at 36"? Considering making them my tire purchase when I get 37's and was wondering what the exact measurement for them was. My 35's are really 33.75's but I run 25 psi.

I say if your ready for a PR44 then get that before getting a heavy tire like the Toyo's. I prefer peace of mind first but thats just me. pretty sure you'll get differing opinions on this topic.

 

My 37 km2s with 28 psi measured 35.5 inches. I took the measurement for my procal.

 

Thanks man. Love my 35's and want 37's to get a real 35"

 

How do you measure the tire to get an accurate measurement ?

 

With weight on veh. From ground to top of tread.
