Thats a pretty variable question. it depends on your rig. The crop sprayers drive safely with 68" tall tires. My 38.5" tsl's are horrible on the road though. I think they are safe, but they ride very rough.

Same here, 38.5 TSL' son the road sucked, but have seen rigs running over 44" on the road (aside from fullsize trucks). I think the 40" range is the borderline.

I too had a friend with 38.5" TSL's that sucked on the road. 38X12.50's aren't nearly as bad, though they're about 2" shorter & 20lbs lighter.

Friend of mine just put 44s on his 95 Ram, does 70-80 with it and the only bitch is not enough motor.

My 44's handle just fine even up to 75-80mph (don't normally go that fast though ).

I've got a friend with a little Toyota on 46's and it is plenty safe.


I'd say it all depends on your exact setup (especially steering, suspension, etc.), how balanced the tires are, etc.
