i put about 4k miles on my mastercraft 35`s with no signs of any wear.i then leveled the truck,and since then have put about 2k more miles on it.now im getting a little cupping starting to show on the fronts.my alignment guy said the truck wouldnt fit on his machine with the 35`s on it and i dont have my old tires anymore...is this a toe in problem from the lift up-front?i havent done any red-neck aligning on it yet,but will probably get to it this weekend sometime.any input would be appreciated,,thanks.....................bama

 

How fast do you take corners? lol That CTD is pretty heavy!

 

Its not the alignment...its the tires...with those big tires you must rotate them every 3-5k to make them wear evenly...had the same issue with my 35's....pro comps and coopers.....try it...and let me know how you make out

 

thanks white lightning,,,,,,ive been reading a ton of old threads,and thats pretty much the consensus...just keep them rotated.my tire guy rotates and rebalances free every 5k anyway,so thats the plan...............bama

 

I don't have aftermarket tires but my buddy owns a tire business and showed me a cool trick. He said alot of abnormal wear is caused by incorrect inflation. Take some white chalk ( you know the blackboard stuff) and mark a line across your tire. Drive 30 feet and check the chalk line. It should be evenly rubbed /worn off at the correct tire pressure. It's called the tire "contact patch" and on my rig, 265/70/17 it is 50 psi front and 40 psi rear empty no load or towing.

 

I agree tire pressure does have a lot to do with tread wear. I run 35 bfg A/T and when i am not towing anything I run 35psi fronts, and 32 in the rears. this setup has seemed to help my tire wear. just remember when you go to tow something fill your backs to thier rated psi
