Just done a 4000klm trip on the new 33" MTZ tyres.
We were loaded probably near GVM.
Set front pressure at 34psi cold measured footprint length then set rears to same footprint, the tyre had 42psi to match the fronts.
Hot the went up to 37 and 47 psi. Rode well, reasonably quiet and as they were new I measured wear and they were all about the same 0.9 - 1.1mm the right front wearing the most.
Have yet to air down and try them off road but impressed on road thats for sure.
Had STT's before and those buggers were noisy when worn. Be interesting to see what these do
