Just ordered a set. Wanted to know if any one is running 275/60/20 on their trucks and what psi do you keep them at???
Great info. That is old schoolGet you a piece of chalk and go to a road where there is no traffic a side street will work fine. Take the chalk and run it sideways across the tread of the tire from the inside to the outside, set your tire pressure at 60 PSI to start, now drive down the street a ways to wear off the chalk, if you have chalk on the inside and outside edges of the tread you can lower the tire pressure some, only remove 5 PSI at a time and drive some more and check again, keep dropping the tire pressure until the tire no longer has any chalk on the tread, you have now reached a tire pressure that will evenly wear the tread of the tire.
For the chalk buy some of that chalk used for children to write on the ground with as that should be easy to find.
I think it may be related to Discount Tire, I have a set of General ATX in 33x12.5x20 from them and until this last rotation and balance they could not get these tires right, this time they did and I don't think I will have them rebalance again, just rotate. I was starting to think the General tires were just not good, but now they are smooth. I don't see many larger size tires coming in and out of there and maybe they just don't have the expertise, don't know.I've had mine nearly 60,000 miles. I run them at 40-42 psi. Had 1 tire that kept leaking down. Discount Tire couldn't find the leak and last week it got a puncture on the road on my way home. New tire, problem solved. Only negative on them is they've not been able to balance them. Always had a shake and shimmy at 55-70mph, so I drive faster so it's not as noticeable 😁
