I have checked the previous posts about 31" tire fitment.
But still have some questions.

1- Currently I have 30x9,5x15 maxxis buckshot mudders on, it's advertised as 30" tire, but specs says 29,5", now Im thinking about to swap 31" BF Goodrich A/T tires which is advertised as 31' but specs says 30.5", why is the difference on specs and addvertised specs?

2- Does 31" tires rub if I crank it up the front and replace the shackles with the longer ones ie.2" longer?

3- Whats the lengt of the shackle to lift rear end 2" ?

Thanks

 

You wont have any rubbing issues with a tbar crank and new shackles, other than at full crank.They are going to be 4 inches longer than stock, so they are going to be about 10" long with holes at 8" center to center. Those are the specs of my shackles that I am putting on. I am waiting to slap them in until my wife is done being pregnant, so she isn't trying to climb any higher than she has to.

 

Thanks for the reply

welcome to the upcoming baby congrats from now.
