What tires not to buy for Heavy Duty Trucks!!!

[AH64ID]

Most new tires will be mushy when new, it takes a while to break them in, for the rubber to take a "set", the owners manual even talks about this. High air pressure will usually not help since the side wall is not the problem, it is the tread actually moving on the belts.

Good point, the rubber needs to get hot and the more air you have the less heat it will see.

All new rubber on the drive tires of an 18 wheeler will scare you to death the first few days, it feels like the tractor is sliding and wants to jack knife every corner you take.



A blocky deep traction tread will make it seem almost undriveable.



A full week or better before they settle down.



I'm sure that is what the OP is experiencing. The tires need to cure or take a set, whatever term applies.



I put 700 miles a week at least on one or the other CTDs I own, it goes away quickly for me.

If you only drive 100 miles a week it will be a longer process by nature.
