I am running Hercules Trail Digger MTX's 235x7515 & Love them. Great bite & minimual road noise.

 

About to make the 1000km trip from Vancouver to Calgary.

Im getting the Firestone Destination A/Ts (235/75/r15) for my Blazer installed before the drive out on Thursday. Reviews sound good and sounds like a non-issue moving to the 75 from the 70 with my truck.

Looking forward to feeling the fresh tires hit the road, I'll be able to report back how they handle Canadian mountain winters in a couple weeks.

 

Still have them! No issues at all.

 

If you have a 3:42 rear ratio you will read about 3-6 % slower on the speedo. (example 50 MPH is reading 47 )

 

I've read 3% and shrugged it off. I'll pay a little closer attention if it's 6%! I'm normally pretty light on the gas pedal as is so I'm not anticipating getting burned by a slightly low reading on the speedometer.
