My bastard 33x12.50x15 tire combo;
TSL Radials in the front
TSL Boggers in the rear
The first day I ran 25 on the road getting to TB. It's what I always ran when I had TSL Radials all the way around, worked good. With the Boggers on the rear, the damn thing followed every rut, ridge, crack in the pavement and I was fighting the steering wheel all the way there.
On the way home I put em up to 27 and it was a big improvement.
I used to always run 15 off road with the Radials all the way around, and worked good. I played with 12, bent a rim, and 17-18 was too stiff.
First day this time I ran 16, Radials were fine, Boggers way too stiff.
Second day I went down to 13. Better, but if I wheel the truck more o9n that combo I'll have to go a little less in the rear. Boggers just too stiff
