My current tire size is 305/35/24
I currently have about 120,000 miles on my rig I started noticing this problem after a couple of months of driving the truck off the lot when it only had about half of the miles it has now about 4 years ago (on stock tires).
It’s a clean title and Clean Car fax so I know it wasn’t wrecked or anything like that. As far as the alignment charts go I’ve never understood them so I never paid much attention to them (my mistake). Although I’m still under warranty for my alignment what should the proper specs be so I can take her back. Should I replace rods first? What’s would be suggested to do?
That is a considerably larger wheel and lower profile tire than what the truck was designed for, so IMHO it would only compound the problem.
First thing I would do is go back to the stock wheel and tire size, when you get the truck right, then put the larger wheels on.
I don't know off hand what the stock numbers are supposed to be, the point was to see if your truck needed large adjustments frequently, which would suggest there is a something damaged or worn. I would take it to a reputable shop and NOT ask them to do an alignment, but tell them the truck wont HOLD an alignment and give them the history. Now, you need to go to a place you trust, because you are basically telling them you know you have a problem and giving them a blank check. When dropping off, tell them you expect the repairs to fix the alignment/tire wear issues and you need some sort of guarantee it will (I am willing to bet no shop will on the aftermarket wheels).
I am not trying to talk you out of your big wheels, but giving you advice that will help you find the answer.
I know this is a grey area, I have several buddies that are dealer techs and this is an issue for many makes and models.
